1 Introduction to provisioning Provisioning a storage system requires balancing the costs of the solution with the benefits that the solution provides. The following is an overview of provisioning strategies that you can implement on the HP XP7 Storage to support your business. About provisioning Provisioning is a method of managing storage system devices or volumes. Some provisioning methods are host-based, while others use existing storage system capabilities such as concatenated array groups.
The alternative is to use a host-based Logical Volume Manager (LVM) when the planned workloads require either more space or IOPS capacity than the individual physical volumes can provide. LVM is the disk management feature available on UNIX-based operating systems, including Linux, that manages their logical volumes.
When to use fixed-sized provisioning Fixed-sized provisioning is a best fit in the following scenarios: • When custom-sized provisioning is not supported. Custom-sized provisioning Custom-sized (or variable-sized) provisioning has more flexibility than fixed-sized provisioning and is the traditional storage-based volume management strategy typically used to organize storage space.
Virtual LUN software is used to configure custom-sized provisioning. For detailed information, see “Configuring custom-sized provisioning” (page 43). Thin Provisioning Overview Thin provisioning is an approach to managing storage that maximizes physical storage capacity. Instead of reserving a fixed amount of storage for a volume, it simply assigns capacity from the available physical pool when data is actually written to disk.
Thin Provisioning is more efficient than traditional provisioning strategies. It is implemented by creating one or more Thin Provisioning pools (THP pools) of physical storage space using multiple LDEVs. Then, you can establish virtual THP volumes (THP V-VOLs) and connect them to the individual THP pools. In this way, capacity to support data can be randomly assigned on demand within the pool. THP V-VOLs are of a user-specified logical size without any corresponding physical space.
Advantages Without Thin Provisioning With Thin Provisioning Reduces management labor and increases availability of storage volumes for replication As the expected physical disk capacity is purchased, the unused capacity of the storage system also needs to be managed on the storage system and on licensed HP XP7 Storage products. HP XP7 Storage product licenses are based on used capacity rather than the total defined capacity.
Automated tiering of physical storage is the next step for thin provisioned enterprise arrays. Automated tiering is the ability of the array to dynamically monitor and relocate data on the optimum tier of storage based on performance requirements. It focuses on data segments rather than entire volumes. The functionality is entirely within the array without any mandated host level involvement. Smart Tiers adds another layer to the thin provisioned environment.
When to use Smart Tiers Smart Tiers is the best fit in an environment in which Thin Provisioning is a good fit. For detailed information, see “Configuring thin provisioning ” (page 61). Data retention strategies After provisioning your system, you can assign access attributes to open-system volumes to protect the volume against read, write, and copy operations and to prevent users from configuring LU paths and command devices. Use the Data Retention to assign access attributes.
• Migration: Auto LUN (contact HP Technical Support) • Partitioning: Cache Partition (XP7 Performance for Open and Mainframe Systems User Guide) Key terms The following are provisioning key terms: Term Description access attributes Security function used to control the access to a logical volume. Access attributes are assigned to each volume: read only, read/write, and protect. CV (variable volume) Customized Volume. A fixed volume that is divided into arbitrary sizes.
System requirements • The HP XP7 Storage hardware, microcode, and Remote Web Console essential for operating the storage system be installed and configured for use. • A HP XP7 Storage. • The storage system must have parity groups installed. • A Remote Web Console client computer. Shared memory requirements CAUTION: • The required shared memory is installed by your HP representative. • Before the shared memory is uninstalled, all Thin Provisioning and Smart Tiers pools must be deleted.
Total capacity of all pools Required shared memory capacity If the total capacity satisfies both of following: 32 GB • More than 3.4 PB • 7.9 PB or less If the total capacity satisfies both of following: 48 GB • More than 7.9 PB • 12.3 PB or less About cache management devices Cache management devices are associated with volumes (LDEVs) and used to manage caches. One volume (LDEV) requires at least one cache management device. An entire system can manage up to 65,280 cache management devices.
2 Managing Virtual Storage Machine Resources The virtual storage machine is the unit that is used to manage virtualized resources for each storage system. For program products with global virtualization functions, a virtual storage machine is created in the storage system. For example, if nondisruptive migration is used to migrate a storage system to HP XP7 Storage, the virtualized storage system is the migration source storage system.
LDEVs for which virtualization management is enabled LDEVs that satisfy one of these conditions: • The model name and serial number of the virtual storage machine that manages a resource group with LDEVs is different than the storage system involved in the operation. • The model name and serial number of the virtual storage machine that manages a resource group with LDEVs is the same as the storage system involved in the operation. Yet, the values of the virtual LDEV ID and the LDEV ID are different.
If the pair is created under the above conditions, the following are displayed as results of executing the pairdisplay command: • Serial number of the virtual storage machine in the Seq# field • Virtual LDEV number in the LDEV# field You can create pairs by specifying both of the following in the HORCM_LDEV parameters of the configuration definition file: • Serial number of the physical storage system in Serial# • Physical LDEV number in CU:LDEV(LDEV#) If the pair is created under the above conditio
3 Configuring resource groups The Storage Administrator can divide a provisioned storage system into resource groups that allow managing the storage system as multiple virtual private storage systems. Configuring resource groups involves creating resource groups, moving storage system resources into the resource groups, and assigning resource groups to user groups. Resource groups can be set up on both open and mainframe systems. Resource Partition software is required.
The Security Administrator in the system division creates resource groups for each division in the storage system and assigns them to the respective divisions. The Storage Administrator in Division A can manage the resource groups for Division A, but cannot access the resource groups for Division B. In the same manner, the Storage Administrator in Division B can manage the resource groups for Division B, but cannot access the resource groups for Division A.
Example of resource groups not sharing ports If you assign ports to each resource group without sharing, performance can be maintained on a different port even if the bulk of I/O is issued from one side port. The following shows a system configuration example of an in-house system division providing the virtual private storage system for two divisions. Divisions A and B each use individual assigned ports and parity groups. In this example, they do not share a port.
After the above procedures, the Storage Administrators in A and B divisions can access the resource groups allocated to their own division. Meta_resource The meta_resource is a resource group comprised of additional resources (other than external volumes) and the resources that exist on the storage system before the Resource Partition is installed.
Resource group license requirements Use of Resource Partition on the HP XP7 Storage requires the following: • A license key for Resource Partition software. For details about the license key or product installation, see the HP XP7 Remote Web Console User Guide. Resource group rules, restrictions, and guidelines Rules • The maximum number of resource groups that can be created on a storage system is 1023.

For example, click Select Parity Groups. 2. Select resources from the Available resource-name table. 3. Click Add resource-name table. The added resources move to the Selected resource-name table. You can click Remove to move resources from the Selected to the Available resource-name table. 4. Click OK.
7. In the Confirm window, confirm the settings, in Task Name type a unique name for this task or accept the default, and then click Apply. If Go to tasks window for status is checked, the Tasks window opens. Removing resources from a resource group Before removing remove resources from a resource group, consider the following: • The resources removed from a resource group are returned to meta_resource. • Resources cannot be deleted from the meta_resource.
5. In the Confirm window, confirm the settings, in Task Name type a unique name for this task or accept the default, and then click Apply. If you select a row and click Detail, the Resource Group Properties window appears. If Go to tasks window for status is checked, the Tasks window opens. Deleting a resource group The Security Administrator (View & Modify) role is required to perform this task. You cannot delete the following: • The meta_resource. • A resource group that is assigned to a user group.

Operation name Condition Shred LDEVs When you specify LDEVs and open the Shred LDEVs window, the specified LDEVs must be assigned to the Storage Administrator group permitted to manage them.
4 Configuring custom-sized provisioning Configuring custom-sized provisioning involves creating and configuring a customized volume (CV). A CV is a fixed-sized volume that is divided into arbitrary sizes. Virtual LUN functions Virtual LUN function is used to create, configure, or delete a customized volume (LDEV). The Virtual LUN function is an open systems function available in Open Volume Management software. A parity group usually consists of some fixed-sized volumes (FVs) and some free space.
Parameter Open system Minimum size for one Virtual LUN 36,000 KB (+ control cylinders) volume 48,000 KB (50 cylinders) Maximum size for one Virtual LUN volume See “CV capacity by emulation type for See “CV capacity by emulation type for open systems” (page 44). open systems” (page 44).
remaining free space generated when multiple CVs are created may be smaller than the free space in the parity group when one CV is created. When using RAID Manager, the specified size of CVs is created regardless of the capacity calculation. Therefore, even if the same capacity size (for example, 1 TB) appears, the actual capacity size might be different between the CVs created by RAID Manager and the CVs created by Remote Web Console.
ceil(ceil(user-specified-CV-capacity * 1024 / capacity-of-a-slot) / 15) * capacity-of-a-slot * 15 where • the value enclosed in ceil( ) must be rounded up to the nearest whole number. • user-specified-CV-capacity is expressed in megabytes. • capacity-of-a-slot is expressed in kilobytes. The capacity of a slot depends on volume emulation types (see “Capacity of a slot” (page 47)). • The resulting user area capacity is expressed in kilobytes.
the capacity values shown might have a margin of error due to unit conversion reasons. If you need to know the exact LDEV capacity, select block as the capacity unit. • The resulting entire capacity is expressed in blocks.
As the result of the Virtual LUN operations, a parity group contains FVs, CVs, and free spaces that are delimited in logical cylinders. Sequential free spaces are combined into a single free space. The following depicts an example of configuring volumes in a parity group: Create LDEV function Use the Create LDEV function to create a customized variable-sized volume. Use Virtual LUN to create an open-systems volume. The following depicts an example of creating customized volumes.
Procedure 6 To create an LDEV 1. 2. 3. 4. 5. In the Remote Web Console main window, in the Storage Systems tree, select the resource to view in the tab, and then click Create LDEVs.

Before registering an LDEV, you may need to change the LDEV settings. 1.
1. 2. In the Storage Systems tree of the Remote Web Console main window, select the resource of the tab you want to view. If Blocked does not appear in the Status column, you can use the following steps to block the LDEV. If Blocked does appear in the column, you can skip the remaining steps. 3. Select the LDEV. You can select multiple LDEVs that are listed together or separately. 4. 5. Open the Block LDEVs window in one of 2 ways. • Click More Actions > Block LDEVs.
3. Select the LDEV. You can select multiple LDEVs that are listed together or separately. 4. 5. Open the Restore LDEVs window in one of 2 ways. • Click More Actions > Restore LDEVs. • From the Actions menu, select Logical Device > Restore LDEVs. Note the settings in the Confirm window and enter a unique Task Name or accept the default and click Apply. If Go to tasks window for status is checked, the Tasks window opens.
You can convert one or more of the LDEVs on a selected parity group into free space by deleting the LDEVs. That free space can be used to either create one or more variable-sized volumes (CVs) using the Create LDEVs function, or left as free space for future use. WARNING! Deleting LDEVs will erase your data. Back up your data before deleting LDEVs.
The following table lists which formatting functions can be used on which LDEV types. Formatting function Corresponding volume Normal Format Internal volume Virtual volume External volume Quick Format Internal volume Storage system operation when LDEVs are formatted The storage system acts in one of two ways immediately after an LDEV is added, depending on the default settings in the storage system. • The storage system automatically formats the added LDEV. This is the default action.
Particularly, in the following cases of quick format operations, due to the load concentration on a specific component at the same time, the I/O performance of the host may decrease while performing of the quick format. • • In a configuration that satisfies both of these conditions, many quick formats started at the same time. ◦ The number of modules is one or two.
Item Description groups that have not undergone but can undergo Quick Format, use the following formula: 72 - X - Y Where: X indicates the number of parity groups on which Quick Format is being performed. Y indicates the number of parity groups where all volumes are blocked during the Quick Format. Storage system is powered off The Quick Format operation resumes when power is turned back on.

Before and after changes are made, it is recommended that the cache write-pending rate (%) for all CLPRs is lower than 50%.
5 Configuring thin provisioning Thin provisioning technology allows you to allocate virtual storage capacity based on anticipated future capacity needs, using virtual volumes instead of physical disks. Thin provisioning is an optional provisioning strategy for both open and mainframe systems. Thin provisioning is implemented by creating one or more Thin Provisioning pools (THP pools) of physical storage space.
Items Requirements However, the upper limit of total capacity of all pools is 12.3 PB if shared memory is installed. Max number of pool-VOLs From 1 to 1,024 volumes (per pool). A volume can be registered as a pool-VOL to one pool only. Maximum number of Up to a total of 128 pools per storage system. This is the total number of Thin Provisioning pools (including Smart Tiers) pools, and Fast Snap pools. Pool IDs (0 to 127) are assigned as pool identifiers.
Items Requirements • Volumes whose LDEV status is other than Normal or Normal (Quick Format) You cannot specify volumes in blocked status or volumes in copying process. • Command devices Emulation type OPEN-V RAID level for a Thin All RAID levels of pool-VOLs can be added. Pool-VOLs of RAID 5, RAID 6, RAID 1, and the Provisioning pool external volume can coexist in the same pool.
Items Requirements LDEV format The LDEV format operation can be performed on pool-VOLs if one of these conditions is satisfied: • The THP V-VOL defined for the pool does not exist. • All THP V-VOLs defined for the pool are blocked. Path definition You cannot specify a volume with a path definition as a pool-VOL. THP V-VOL requirements Items Requirements Volume type THP V-VOL (V-VOL) The LDEV number is handled in the same way as for normal volumes.
The following requirements are important when increasing the THP V-VOL capacity: • The THP V-VOL to be increased is not shared with a HP XP7 Storage product that does not allow increasing the THP V-VOL (See “Increasing THP V-VOL capacity” (page 151)). • The THP V-VOL is not undergoing LDEV formatting. • The capacity to be added to the THP V-VOL must be specified within the range indicated below LDEV Capacity in the Expand V-VOLs window.
OS File System Metadata Writing Pool Capacity Consumed effectiveness of reducing the pool capacity consumption decreases. Linux XFS Ext2 Ext3 Writes metadata in Allocation Group Size intervals. O Writes metadata in 128-MB increments. O Depends upon allocation group size. The amount of pool space consumed will be approximately [THP V-VOL Size]*[42 MB/Allocation Group Size] About 33% of the size of the THP V-VOL. The default block size for these file systems is 4 KB.
Using Thin Provisioning or Smart Tiers with other HP XP7 Storage products Interoperability of THP V-VOLs and pool-VOLs THP V-VOLs and pool-VOLs can be used in conjunction with other HP XP7 Storage products. The following table lists the operations that are permitted and not permitted.

Resource Partition See “Resource group rules, restrictions, and guidelines” (page 31) for the conditions of resources that are necessary in the operation of other HP software and the precautions required when using Resource Partition. Thin Provisioning workflow The following diagram shows the steps for a Storage Administrator to follow in setting up Thin Provisioning on a storage system.
Smart Tiers About tiered storage In a tiered storage environment, storage tiers can be configured to accommodate different categories of data. A tier is a group of storage media (pool volumes) in a THP pool. Tiers are determined by a single storage media type. A storage tier can be one type of data drive, including SSD, SAS, or external volumes. Media of high-speed performance make up the upper tiers. Media of low-speed response become the lower tiers.
In Auto execution mode, monitoring and relocation are continuous and automatically scheduled. In Manual execution mode, the following operations are initiated manually.
In both execution modes, relocation of data is automatically determined based on monitoring results. The settings for these execution modes can be changed nondisruptively while the pool is in use.
• Auto execution mode Auto execution mode performs monitoring and tier relocation based on information collected by monitoring at a specified constant frequency: from 0.5, 1, 2, 4, or 8 hours. All Auto execution mode cycle frequencies have a starting point at midnight (00:00). For example, if you select a 1 hour monitoring period, the starting times would be 00:00, 01:00, 02:00, 03:00, and so on.
In auto execution mode, the collection of monitoring data and tier relocation operations are performed in parallel in the next cycle. Data from these parallel processes are stored in two separate fields. • Data while monitoring is in progress in the next cycle. • Fixed monitoring information used in tier reliocation. • Manual execution mode You can start and stop performance monitoring and tier relocation at any time.
Figure 7 Collection of monitoring data to tier relocation workflow in manual execution mode Case 1: If the second collection of the monitoring information is finished during the first tier relocation, the latest monitoring information is the second collection. In that case, the first collection of monitoring information is referenced only after the first tier relocation has completed.
In that case, the third collection of the monitoring information is started after the first tier relocation is stopped or tier relocation has completed. The collection of the monitoring information is not started under these conditions as well: • When the second tier relocation is performed, the fourth collection of monitoring information cannot be started. • When the third tier relocation is performed, the fifth collection of monitoring information cannot be started.
Explanation of the relocation flow: 1. Allocate pages and map them to THP V-VOLs Pages are allocated and mapped to THP V-VOLs on an on-demand basis. Page allocation occurs when a write is performed to an area of any THP V-VOL that does not already have a page mapped to that location. Normally, a free page is selected for allocation from an upper tier with a free page. If the capacity of the upper tier is insufficient for the allocation, the pages are allocated to the nearest lower tier.
4. Determine the tier range values The page is allocated to the appropriate tier according to performance monitoring information. The tier is determined as follows. 1. Determine the tier boundary The tier range value of a tier is calculated using the frequency distribution graph. This acts as a boundary value that separates tiers The pages of higher I/O load are allocated to the upper tier in sequence.
allocated during the monitoring cycle. Pages that are not allocated during performance monitoring are not candidates for tier relocation. • Tier relocation can be performed concurrently on up to eight pools. If more than eight pools are specified, relocation of the ninth pool starts after relocation of any of the first eight pools has completed.
Monitoring information or execution conditions Status of data collection in progress Status of fixed monitoring information used in tier relocation Tier relocation operations Solutions When V-VOLs are deleted Volume is not monitored. Only monitoring information on the volume is invalid. Tier relocation of the volume is suspended. N/A When execution Suspended. mode is changed to Manual from Auto or vice versa. Monitoring information collected before suspension is valid. Suspended.

When the depletion Continued. threshold of the pool is nearly exceeded during relocation. No effect on the fixed Suspended. monitoring information. The monitoring information collected during the previous cycle continues to be valid.
Setting external volumes for each tier If you use external volumes as pool-VOLs, you can put the external volumes in tiers by setting the External LDEV Tier Rank for the external volumes. The External LDEV Tier Rank consists of the following three types: High, Middle, and Low.
Figure 10 Workflow of a new page assignment Tier relocation workflow: Tier relocation is performed taking advantage of the buffer space allocated for tier relocation, as mentioned above. Tier relocation is also performed to secure the space reserved in each tier for new page assignment. The area is called the buffer space for new page assignments. When tier relocation is performed, Smart Tiers reserves buffer spaces for relocation and new page assignment.
Manual execution mode In Manual execution mode, you can manually collect monitoring data and relocate a tier. You can issue commands to manually: 1. Start monitoring. 2. Stop monitoring. 3. Perform tier relocation. The following illustrates tier relocation processing in Manual execution mode: Notes on performing monitoring 88 • You can collect the monitoring data even while performing the relocation. • After stopping the monitoring, the tier range is automatically calculated.
• The latest available monitoring information, which is collected just before the relocation is performed, is used for the relocation processing. • When the relocation is performed, the status of the monitor information must be valid. Viewing monitor and tier relocation information: Information is displayed on the following items in the GUI windows: • Monitoring Status on “Pools window” (page 309), “Pools: Volume tabs” (page 314), and “View Pool Management Status window” (page 375).
• Relocation Result on “Pools window” (page 309), “Pools: Volume tabs” (page 314), and “View Pool Management Status window” (page 375). Displays the status of the tier relocation processing. • ◦ In Progress: The status of Pool Management Task is Waiting for Relocation or Relocating. ◦ Completed: The tier relocation operation is not in progress, or the tier relocation is complete. ◦ Uncompleted (n% relocated): The tier relocation is suspended at the indicated percentage progression.
Notes on performing monitoring • You can collect the monitoring data even while performing the relocation. • After stopping the monitoring, the tier range is automatically calculated. • The latest available monitoring information, which is collected just before the relocation is performed, is used for the relocation processing. • When the relocation is performed, the status of the monitor information must be valid.

Tiering policy expansion In the current release, the tiering policy concept has been expanded to provide new options: • Custom policies. You can define up to 26 new policies (Level6(6) - Level31(31)) in addition to the existing six (All(0), Level1(1), Level2(2), Level3(3), Level4(4), and Level5(5)). See “Setting tiering policy on a THP V-VOL” (page 99). A custom policy can be set for a THP V-VOL when it is created and changed, if necessary, after creation. NOTE: Custom policies cannot be renamed.
The following figure shows an example of data allocation when setting the tiering policy to Level1(1) (see Level1(1) in “Tiering policy levels” (page 100)). In this case, pages in the THP V-VOL are relocated to tier 1, and are not relocated to other tiers. Setting tiering policy on a THP V-VOL The setting of a tiering policy for a THP V-VOL is optional. If one is not selected, the default is the All(0) tiering policy level. The available levels are listed in “Tiering policy levels” (page 100)).
Example of deleting a tier If a tier no longer has any pool-VOLs when you delete them, the tier is deleted from the pool. The following figure illustrates deleting a tier. For more information about tiering policy and groups, see “Tiering policy levels” (page 100). Tiering policy levels Tiering policy 1 tier pool 2 tier pool 3 tier pool Note All(0) Single Tier Both tiers All 3 tiers Default Tiering Policy Level1(1) Same as All(0) Tier 1 Tier 1 Data is located to the Top Tier.
The following table shows how tiering policy is shown in the performance graph. How the graph appears depends on the number of tiers set in a pool and tiering policy level selected when viewing the performance graph. Tiering policy selected with performance graph V-VOL displayed in the performance graph All(0) In the performance graph, you can display a frequency distribution of a THP V-VOL, set to all tiers.
Reserving tier capacity when setting a tiering policy If you set the tiering policy of a THP-VOL, the THP-VOL used capacity and the I/O performance limitation are reserved from the tier. The reserved limit performance per page is calculated as follows: The reserved limit performance per page = (The performance limit of the tier) ÷ (The number of pages in the tier). A THP-VOL without a tiering policy setting uses the unreserved area in the pool.
diagram below, tier 1 is reserved first. If the capacity of tier 1 is deficient at this point, tier 2 is reserved automatically. For details, see “Notes on tiering policy settings” (page 104). Tier reservation priority Tiering policy Reserved tier 1 Level1(1) Tier 1 2 Level3(3) Tier 2 3 Level5(5) Tier 3 From 4 to 29 From Level6(6) to Level31(31) The custom policy whose number is small is prioritized. Tier 1: From Level6(6) to Level31(31), each of the Tier1 Min values are reserved.
Notes on tiering policy settings • If Auto is set as the execution mode, tier relocation is performed based on the monitoring cycle. Therefore, when the tiering policy setting is changed, tier relocation will automatically implement the tiering policy at the end of the current monitoring cycle. See Example 1 in “Execution mode settings and tiering policy” (page 109).
Tiering Policy Allocation capacity considerations Allocation capacities in each tier. ◦ Tier1: The setting value(%) in Tier1 Min. ◦ Tier2: The value deducted Tier1 Max(%) and Tier3 Max(%) from 100(%). ◦ Tier3: The setting value(%) in Tier3 Min. Second phase: Tier range and I/O performance. Capacities deducted from the allocated capacities of the first phase from the total used capacity, are allocated to each tier.
Number Condition Order of new page allocation 1 T1 MIN = 100% Same as Level1(1) 2 T1 MAX = 0% Same as Level5(5) 3 T1 MAX > 0% Same as All(0) Tiering policy When specifying High When specifying Middle All From tier 1, 2, to 3. From tier 2, 3, to 1. From tier 3, 2, to 1. Specifying High, Middle or Low to the assignment sequence is effective. Level 1 From tier 1, 2, to 3. From tier 1, 2, to 3. From tier 1, 2, to 3. Assignment sequences when High, Middle, and Low are same.
example, three LDEVs are relocated in each period, but the number of LDEVs to relocate may change by the relocation cycle or the data size.
Tier of deleted pool-VOLs Order in which pages are allocated to tiers Description If there is no free space in Tier 1 and Tier 2, pages are allocated to Tier 3. Tier 3 Tier 3, Tier 2, and Tier 1 If there is free space in Tier 3, pages are allocated to Tier 3. If there is no free space in Tier 3, pages are allocated to Tier 2. If there is no free space in Tier 2 and Tier 3, pages are allocated to Tier 1. The following table describes page allocation in a 2-tier configuration.
• Reclaiming zero pages in a page release request issued by the host with the Write Same command, for example. • Performing tier relocations several times If you expand the pool capacity, Thin Provisioning moves data to the added space on a per-page basis. When the data is moved, the usage rate among parity groups of the pool-VOLs is rebalanced. Host I/O performance may decrease when data is moved.

Smart Tiers workflow The following diagram shows the flow of work for a Storage Administrator to set up Smart Tiers on the storage system. As shown in the diagram,Remote Web Console and RAID Manager have different workflows. The details about how to set up Smart Tiers using Remote Web Console are covered in subsequent topics. For details about how to set up Smart Tiers using RAID Manager, see the HP XP7 RAID Manager Reference Guide and HP XP7 RAID Manager User Guide.
• In RAID Manager, when creating a pool, you cannot enable Smart Pool and cannot register multiple media as pool-VOLs. Before making tiers, enable Smart Pool. • Enabling Smart Pool from RAID Manager automatically sets Tier Management to Manual. To change Tier Management to Auto, you must do this in Remote Web Console. • If you delete a pool, its pool-VOLs (LDEVs) will be blocked. If they are blocked, format them before using them.

Working with pools About pools Thin Provisioning requires the use of pools. A pool consists of more than one pool-VOL.
Thin Provisioning does not automatically balance the usage levels among pool-VOLs if the cache memory is not redundant or if the pool usage reaches up to the threshold. The pool-VOLs contained in a pool can be added or deleted. Removing a pool-VOL does not delete the pool or any related THP V-VOLs. You must delete all THP V-VOLs related to the pool before the pool can be deleted. When the pool is deleted, all data in the pool is also deleted. Pool status The following table describes the pool status.
If multiple pool-VOLs of the same data drive type exist, the priority of each is determined by the internal index of the storage system. For Thin Provisioning when selecting pool-VOLs manually The Storage Administrator (Provisioning) role is required to perform this task. To create pools by selecting pool-VOLs manually: 1. In the Storage Systems tree on the left pane of the top window, select Pool. The Pool window appears. 2. Click Create Pools. The Create Pools windows appears. 3. 4. 5. 6. 7.

SIMs and as SNMP traps to the open-systems host. See “Monitoring pool usage levels” (page 137) for more information. You can provision a larger virtual capacity beyond the pool capacity by using THP V-VOLs of Thin Provisioning or Smart Tiers. However, when the pool’s free capacity is depleted, you can lose access to THP V-VOLs that require more pool capacity.
• ◦ THP V-VOL usage (stored data rates) and elapsed time of pool usage (using Remote Web Console). ◦ Smart Tiers performance monitoring of pool storage Possible tuning actions (without Smart Tiers). The following techniques using Business Copy or Tiered Storage Manager will move a THP V-VOL. ◦ The THP V-VOL is copied using Business Copy from a pool with an I/O bottleneck. For more information, see HP XP7 Business Copy User Guide.
Thresholds Pool utilization thresholds Thin Provisioning monitors pool capacity using thresholds. A threshold is the proportion (%) of used capacity of the pool to the total pool capacity. Each pool has its own pool threshold values. • Warning Threshold: Set the value between 1% and 100%, in 1% increments. The default is 70%. • Depletion Threshold: Set the value between 1% and 100%, in 1% increments. The default is 80%.
The following figure depicts setting the subscription limit of pool capacity. Monitoring total THP-VOL subscription for a pool You can configure the Subscription Limit of total THP-VOL capacity to pool capacity. This prevents a new THP-VOL capacity that exceeds the configured subscription limit from being allocated and is associated with the pool.

• Creating THP V-VOLs. • Increasing THP V-VOL capacity. While the pool capacity is being decreased, if maintenance of cache memory is performed, if the cache memory fails, or if the I/O load to the THP V-VOL related to the pool is high, decreasing the pool capacity process might fail. In this case, check the Tasks window to determine whether processing has abnormally ended. If the processing has ended abnormally, restore the cache memory, and then try decreasing the pool capacity again.
Notes on using Smart Tiers You cannot delete a pool-VOL under these conditions. • If the pool-VOL is deleted, the used capacity of the pool-VOL exceeds the pool threshold. • If the pool-VOL is deleted, the subscription rate of the total V-VOL capacity including the control information exceeds the subscription limit. For details about the formula used to calculate the required pages for one DP-VOL including the control information, see “Pool subscription limit” (page 139).

6 Configuring access attributes After provisioning your system, you can assign access attributes to open-system volumes to protect the volume against read, write, and copy operations and to prevent users from configuring LU paths and command devices. Data Retention software is required to assign access attributes to volumes. About access attributes Open-systems volumes, by default, are subject to read and write operations by open-systems hosts.
Access attributes and permitted operations Access Attribute Read Operations from Hosts Write Operations from Hosts Specified as P-VOL Specified as S-VOL Read/Write Yes Yes Yes Yes Read-only Yes No Depends on the replication No software Protect No No Depends on the replication No software Read/Write and S-VOL disable Yes Yes Yes No Access attribute restrictions Some restrictions apply when you use the following HP XP7 Storage products or functions on a volume that has an access attribu
Assigning an access attribute to a volume If you want to protect volumes against both read and write operations from hosts, change the access attribute to protect. To protect volumes against write operations from hosts and allow read operations, change the access attribute to read-only. In both ways, if you set the attribute to a volume using the GUI, S-VOL Disable is automatically set to prevent data in a volume from being overwritten by replication software.
Procedure 11 To change an access attribute to read-only or protect 1. 2. Navigate to the Remote Web Console as a user assigned to the Storage Administrator (Provisioning) role. In the Remote Web Console main window, click Actions > Other Function > Data Retention to open the Data Retention window. Figure 11 Data Retention window 3. 4. 5. 6. Click to change to Modify mode. Select an LDKC number in the LDKC list, select a group that the CU belongs in the CU Group list, and then click a CU in the tree.
8. 9. Click OK to close the dialog box. In the Data Retention window, click Apply to apply the setting. To extend the retention term later, open the Data Retention window, right-click the volume, and then select Retention Term. Changing an access attribute to read/write Before changing the access attribute from read-only or protect to read/write, considering the following: • Remote Web Console secondary windows must be defined for use in advance.
2. In the Remote Web Console main window, click Actions > Other Function > Data Retention to open the Data Retention window. 3. 4. Click to change to Modify mode. In the Data Retention window, verify which button appears beside Expiration Lock. 5. 6. • If Disable > Enable appears, go to the next step. • If Enable > Disable appears, expiration lock is already enabled. You do not need to follow the rest of this procedure because attempts to change access attribute to read/write are already prohibited.
Remote Web Console secondary windows must be defined for use in advance. When you select Modify from the Data Retention secondary window to disable an S-VOL, other users or programs are prevented from changing storage system settings. When you close the secondary window, Modify mode is released. For more information on Remote Web Console secondary windows and Modify mode, see the HP XP7 Remote Web Console User Guide. Procedure 15 To reserve volumes 1. 2. 3. 4. 5. 6. 7.
7 Managing logical volumes After provisioning your system, you can begin to manage open-system logical volumes. Managing logical volumes includes tasks such as configuring hosts and ports, configuring LU paths, setting LUN security on ports, and setting up fibre channel authentication. LUN Manager is required to manage logical volumes.
You can define paths between a single server host and multiple LUs. The figure shows that each of the two hosts in the host group hg-lnx can access the three LUs. You can also define paths between multiple server hosts and a single LU. The figure shows that the LU identified by the LDKC:CU:LDEV number 00:00:00 is accessible from the two hosts that belong to the hg-lnx host group. The figure also shows that the LUs associated with the hg-lnx host group are addressed by numbers 0000 to 0002.
Restrictions • You cannot define an LU path to journal volumes. • You cannot define an LU path to pool volumes. • When defining LU paths, you must not use RAID Manager and Remote Web Console at the same time. If both programs are used simultaneously, operations may not be performed in the expected order and the storage configuration might be defined incorrectly. Guidelines • If you attempt to apply many settings in the LUN Manager windows, the SVP might be unable to continue processing.
Configuring fibre channel ports Setting the data transfer speed on a fibre channel port The Storage Administrator (Provisioning) role is required to perform this task. As system operation continues, you might notice that a large amount of data is transferred at some ports, but a small amount of data is transferred at other ports.
7. In the Confirm window, confirm the settings, in Task Name type a unique name for this task or accept the default, and then click Apply. If Go to tasks window for status is checked, the Tasks window opens. Addresses for fibre channel ports The following addresses are available for setting fibre channel ports.
Setting the fabric switch The Storage Administrator (Provisioning) role is required to perform this task.

Record the WWN and repeat the above steps for each Fibre Channel device that you want to use. # /usr/sbin/ioscan -fnC lan <- 1 Class I H/W Path Driver S/W State H/W Type Description ============================================================== lan 0 8/0.5 fcT1_cntl CLAIMED INTERFACE HP Fibre Channel Mass Storage Cntl /dev/fcms0 <-2 lan 4 8/4.
register HP-UX hosts to the corresponding host group and register Windows hosts to the other host group. NOTE: cluster. The above example relates to configurations in which all HP-UX hosts are on the same Before you can set LU paths, you must register the hosts in host groups. For example, if HP-UX hosts and Windows hosts are connected to a port, register HP-UX hosts and Windows hosts separately in two different host groups. When registering a host, you must also specify the WWN of the host bus adapters.
1. Click Add New Host under the Available Hosts list. The Add New Host dialog box opens. 2. 3. 4. 5. 6. Enter the desired WWN in the HBA WWN box. If necessary, enter a nickname for the host bus adapter in the Host Name box. Click OK to close the Add New Host dialog box. Select the desired host bus adapter from the Available Hosts list. Select the port to which you want to add the host group. For details about host modes, see “Host modes for host groups” (page 170).
Procedure 19 To define LU paths 1. 2. From the Storage Systems tree, click Ports/Hosts Groups. From the Actions menu, select Logical Device, and then Add LUN Paths. Select the desired LDEVs from the Available LDEVs table, and then click Add. Selected LDEVs are listed in the Selected LDEVs table. 3. 4. Click Next. Select the desired host groups from the Available Host Groups table, and then click Add. Selected host groups are listed in the Selected Host Groups table. 5. 6. 7. 8. Click Next.
4. Select the LUNs tab. Information about LU paths associated with the selected host group appears. 5. Select one or more logical units to which volumes are assigned (if a volume is assigned to a LU, the columns on the right of the LUN column are not empty). When multiple LUs are selected, the same UUID is set to all selected LUs. 6. 7. Click More Actions, and then select Edit UUIDs. In the Edit UUIDs window, in Prefix, type the UUID. If a UUID is already specified, you can change it.
To create an alternate LU path, copy the original LU path from one port to another. For example, if you want to define an alternate for the LU path from the CL1-A port to logical volume 00:00:01, copy the LU path from the CL1-A port to another port.
Managing LU paths You can modify the LU paths configuration with LUN Manager when the system is in operation, but not when host I/O is in progress. Managing LU paths includes the following tasks: • “Deleting LU paths” (page 181) • “Clearing a UUID setting” (page 181) • “Viewing LU path settings” (page 182) Deleting LU paths The Storage Administrator (Provisioning) role is required to perform this task. CAUTION: 1. Do not delete LU paths when host I/O is in progress.
4. In the Confirm window, confirm the settings, in Task Name type a unique name for this task or accept the default, and then click Apply. If Go to tasks window for status is checked, the Tasks window opens. Viewing LU path settings The Storage Administrator (Provisioning) role is required to perform this task. 1. In the Storage Systems tree, click Ports/Host Groups. The list of available ports appears in the tree. 2. In the tree, select a port. The host groups corresponding to the port appear. 3.
LUN security on ports To protect mission-critical data in your storage system from illegal access, apply security policies to logical volumes. Use LUN Manager to enable LUN security on ports to safeguard LUs from illegal access. If LUN security is enabled on ports, host groups affect which host can access which LUs. Hosts can access only the LUs associated with the host group to which the hosts belong. Hosts cannot access LUs associated with other host groups.
Host group 0 is the only host group reserved, by default, for each port. If you use the LUN Manager window to view a list of host groups in a port, host group 0, indicated by 00, usually appears at the top of the list. The default name of host group 0 consists of the port name, a hyphen, and the number 00. For example, the default name of host group 0 for port 1A is 1A-G00. However, you can change the default name of the host group 0. LUN security is disabled, by default, on each port.
Disabling LUN security on a port The Storage Administrator (Provisioning) role is required to perform this task. CAUTION: 1. 2. 3. 4. 5. 6. 7. Do not disable LUN security on a port when host I/O is in progress. Click Ports/Host Groups in the Storage Systems tree. Select the Ports tab. Select the desired port. Select Edit Ports The Edit Ports window opens. Select the Port Security check box, and then select Disable. Click Finish.
1. 2. A host group of the storage system authenticates a host that attempts to connect (authentication of hosts). The host authenticates the connection-target host group of the storage system (authentication of host groups). CAUTION: Because the host bus adapters at present do not support this function, this authentication phase is unusable in the fibre channel environment. 3. A target port of the storage system authenticates a fabric switch that attempts to connect (authentication of fabric switches).
The following diagram illustrates the flow of authentication of hosts in a fibre channel environment. The connection uses cases are detailed below the diagram. Authenticating hosts (Cases A, B, and C) The following cases describe the examples of performing authentication of host groups Case A - The user information of the host is registered on the host group, and authentication of the host is enabled. The host group authenticates the user information sent from the host.
Not authenticating hosts (Case D) Case D is an example of connecting via a host group that does not perform authentication of hosts. The host will connect to the storage system without authentication of the host regardless of whether the host is configured for authentication by host groups with CHAP. In this case, though you need not register user information of the host on the host group, you can register it.
During authentication of hosts, the connection result is determined depending on the combination of the following host group settings: • Setting of the host group in the Port tree: enable ( • Whether the user information of the host that attempts to connect is registered on the host group ) or disable ( ) Port settings and connection results The following table shows the relationships between host group settings and the connection results in authentication of hosts.
Authenticating fabric switches by ports (Cases A, B, and C) • If the user information of the fabric switch is registered on the port, and authentication of the fabric switch is enabled (Case A) Each port authenticates the fabric switch. If the authentication of the fabric switch ends successfully, either of the following actions occurs: ◦ When the fabric switch is configured for mutual authentication, processing continues to authentication of the port.
During authentication of hosts, the connection result is determined depending on the combination of the following port settings: • Setting of the port in the Port tree: enable ( • Whether the user information of the fabric switch that attempts to connect is registered on the port ) or disable ( ) fabric switch settings and connection results The following table shows the relationship between the combinations of port settings and the connection results in authentication of fabric switches.
3. In the Port tree, double-click the Storage System folder. If the storage system contains any fibre channel adapters, the Fibre folder appears below the Storage System folder. 4. Double-click the Fibre folder and fibre channel port icon under the Fibre folder. When you double-click the Fibre folder, the fibre channel ports contained in the storage system appear as icons. If you double-click the fibre channel ports, host groups appear as icons. On the right of each icon appears the host group name.
5. In this dialog box, specify the following user information of the host you want to allow connection. • Group Name: Specify the group name of host bus adapter. Select one from the list. In the list, all the group names of host bus adapters connected to the selected port by the cable appear. • User Name: Specify the WWN of the host bus adapter with up to 16 characters. You can use alphanumeric characters in a user name.
Deleting host user information You can delete registered user information from a host group. Remote Web Console secondary windows must be defined for use in advance. When you select Modify from the Authentication secondary window to delete host user information, other users or programs are prevented from changing storage system settings. When you close the secondary window, Modify mode is released.
6. 7. 8. • Secret: Specify the secret (that is, a password used in CHAP authentication) between 12 to 32 characters. You can use alphanumeric characters, spaces, and the following symbols in a user name: . - + @ _ = : / [ ] , ~ • Re-enter Secret: Specify the secret, again, for confirmation. Click OK to close the Specify Authentication Information dialog box. The specified user information of the port appears in blue in the Authentication Information (Target) list of the Authentication window.
4. 5. 6. 7. 8. Right-click any point in the Port Information list and select Set Port Information. In the Set Port Information dialog box, specify the port information. • Time out: Specify the period of time from when authentication fails to when the next authentication session is ended. This period of time is between 15 to 60 seconds. The initial value of the Time out is 45 seconds.
Remote Web Console secondary windows must be defined for use in advance. When you select Modify from the Authentication secondary window to specify authentication information, other users or programs are prevented from changing storage system settings. When you close the secondary window, Modify mode is released. For more information on Remote Web Console secondary windows and Modify mode, see the HP XP7 Remote Web Console User Guide. 1.
