1 Overview Server Administrator Storage Management provides enhanced features for configuring the locally attached RAID and non-RAID disk storage on a system. Storage Management enables you to perform controller and enclosure functions for all supported RAID and non-RAID controllers and enclosures from a single graphical user interface (GUI) or command-line interface (CLI). The GUI is wizard-driven and includes features for novice and advanced users. The CLI is fully featured and scriptable.
Version Requirements For Controller Firmware And Drivers For Storage Management to function properly, the controllers must have the minimum required version of the firmware and drivers installed. The firmware and drivers listed in the Server Administrator Release Notes refer to the minimum supported version for these controllers. Later versions of the firmware and drivers are also supported. For the most recent driver and firmware requirements, contact your service provider.
Supported Non-RAID Controllers Storage Management supports the following non-RAID controllers: • SAS 6 Gbps Host Bus Adapter (HBA) • Broadcom SAS 9207-8e • Broadcom SAS 9300-8e • Broadcom SAS 9206-16e • SAS 12 Gbps HBA • HBA 330 • HBA 330 MX • HBA 330 MMZ NOTE: Storage Management only enumerates and provides the PCI slot information for Broadcom SAS 9207-8e, SAS 9300-8e and SAS 9206-16e controllers.
2 Getting Started Server Administrator Storage Management is designed for system administrators who implement hardware RAID solutions and understand corporate and small business storage environments. Storage Management enables you to configure the storage components attached to your system. These components include RAID and non-RAID controllers and the channels, ports, enclosures, and disks attached to them.
On A System Running Linux And Any Remote System To start a Server Administrator session on a Linux or any remote system, click the Server Administrator icon on your desktop and log in using an account with Administrator privileges. Or, open a web browser and type one of the following in the address field and press : https://:1311 where is the assigned name for the managed system and 1311 is the default port.
Information Or Configuration On the Properties page, click Information/Configuration to view the property information for a storage object. The Information/ Configuration subtabs also have options for executing storage tasks or launching wizards. Using The Storage Management Command-Line Interface Storage Management has a fully featured command-line interface (CLI). For more information on CLI, see the Server Administrator Command Line Interface User’s Guide.
3 Understanding RAID concepts Storage Management uses the Redundant Array of Independent Disks (RAID) technology to provide Storage Management capability. Understanding Storage Management requires an understanding of RAID concepts, as well as some familiarity with how the RAID controllers and operating system view disk space on your system.
• Striping — Disk striping writes data across all physical disks in a virtual disk. Each stripe consists of consecutive virtual disk data addresses that are mapped in fixed-size units to each physical disk in the virtual disk using a sequential pattern. For example, if the virtual disk includes five physical disks, the stripe writes data to physical disks one through five without repeating any of the physical disks. The amount of space consumed by a stripe is the same on each physical disk.
The following topics provide specific information on how each RAID level or concatenation store data as well as their performance and protection characteristics: • Concatenation • RAID Level 0 (Striping) • RAID Level 1 (Mirroring) • RAID Level 5 (Striping With Distributed Parity) • RAID Level 6 (Striping With Additional Distributed Parity) • RAID Level 50 (Striping Over RAID 5 Sets) • RAID Level 60 (Striping Over RAID 6 Sets) • RAID Level 10 (Striping Over Mirror Sets) • Comparing RAID Leve
• Data fills up the first disk before it is written to the second disk. • No redundant data is stored. When a disk fails, the large virtual disk fails. • No performance gain. • No redundancy. RAID level 0 - striping RAID 0 uses data striping, which is writing data in equal-sized segments across the physical disks. RAID 0 does not provide data redundancy. RAID 0 characteristics: • Groups n disks as one large virtual disk with a capacity of (smallest disk size) *n disks.
RAID 1 characteristics: • • • • • • Groups n + n disks as one virtual disk with the capacity of n disks. The controllers currently supported by Storage Management allow the selection of two disks when creating a RAID 1. Because these disks are mirrored, the total storage capacity is equal to one disk. Data is replicated on both the disks. When a disk fails, the virtual disk still works. The data is read from the mirror of the failed disk. Better read performance, but slightly slower write performance.
RAID 5 characteristics: • • • • • Groups n disks as one large virtual disk with a capacity of (n-1) disks. Redundant information (parity) is alternately stored on all disks. When a disk fails, the virtual disk still works, but it is operating in a degraded state. The data is reconstructed from the surviving disks. Better read performance, but slower write performance. Redundancy for protection of data.
RAID 50 characteristics: • Groups n*s disks as one large virtual disk with a capacity of s*(n-1) disks, where s is the number of spans and n is the number of disks within each span. • Redundant information (parity) is alternately stored on all disks of each RAID 5 span. • Better read performance, but slower write performance. • Requires as much parity information as standard RAID 5. • Data is striped across all spans. RAID 50 is more expensive in terms of disk space.
RAID 60 characteristics: • Groups n*s disks as one large virtual disk with a capacity of s*(n-2) disks, where s is the number of spans and n is the number of disks within each span. • Redundant information (parity) is alternately stored on all disks of each RAID 6 span. • Better read performance, but slower write performance. • Increased redundancy provides greater data protection than a RAID 50. • Requires proportionally as much parity information as RAID 6.
RAID 10 characteristics: • Groups n disks as one large virtual disk with a capacity of (n/2) disks, where n is an even integer. • Mirror images of the data are striped across sets of physical disks. This level provides redundancy through mirroring. • When a disk fails, the virtual disk still works. The data is read from the surviving mirrored disk. • Improved read performance and write performance. • Redundancy for protection of data.
RAID Level Data Availability Read Performance Write Performance Rebuild Performance Minimum Disks Required Suggested Uses RAID 1 Excellent Very Good Good Good 2N (N = 1) Small databases, database logs, and critical information. RAID 5 Good Sequential reads: good. Transactional reads: Very good Fair, unless using writeback cache Fair N + 1 (N = at least Databases and two disks) other read intensive transactional uses.
4 Quick Access To Storage Status And Tasks This section describes various methods to determine the status or health of the storage components on your system and how to quickly launch the available controller tasks.
Table 2. Component Severity Severity Component Status Normal/OK — The component is working as expected. Warning/Non-critical — A probe or other monitoring device has detected a reading for the component that is above or below the acceptable level. The component may still be functioning, but it could fail. The component may also be functioning in an impaired state. Data loss is possible. Critical/Failure/Error/Fatal — The component has either failed or failure is imminent.
NOTE: You may not receive SMART alerts when the I/O of a controller is paused. Using Alarms To Detect Failures Certain storage components have alarms which when enabled, alert you when the component fails. Time Delay In Displaying Configuration Changes When you change the storage configuration, Storage Management quickly generates SNMP traps in response to the configuration changes. The Storage Management, Management Information Base (MIB) is also updated to reflect storage configuration changes.
5 PCI Express Solid-State Device Support This section provides an overview of the Storage Management device management support for Peripheral Component Interconnect Express (PCIe) Solid-State Drive (SSD) and its associated devices like the backplane and extender card. In Storage Management, PCIe SSD appears under Storage in the tree view. Storage Management reports the PCIe SSD devices and its various properties.
• PCIe Solid-State Device Table 3. PCIe SSD Subsystem Properties Properties Description ID Displays the subsystem ID assigned to the PCIe SSD subsystem by Storage Management. Storage Management numbers the controllers and PCIe SSD subsystems attached to the system starting with zero. This number is the same as the PCIe SSD subsystem ID number reported by the omreportcommand. For information on Command Line Interface, see the Server Administrator Command Line Interface User's Guide.
The following table lists the physical device properties for PCIe SSD. Table 4. Physical Device Properties Properties Description Name Displays the name of the PCIe SSD. The name comprises the bay ID and the slot in which the PCIe SSD is installed. State Displays the health state of the PCIe SSD. Bus Protocol Displays the technology that the PCIe SSD is using. Device Protocol Displays the device protocol of the physical device, such as NonVolatile Memory Express (NVMe).
Properties Description Read Only — The drive is in read-only mode. Users must save open files, if any, to another device and replace or remove the device. If this scenario occurs within three years of the device installation, this failure is covered under warranty. The drive is in read-only mode if the value for percent lifetime used is less than 100 percent and that for write protect progress is equal to 90 percent.
Properties Description NOTE: This field is not applicable for NVMe Intel P4800x devices. Physical Device Tasks The physical device tasks for PCIe SSD are as follows: • Blinking And Unblinking • Preparing To Remove A PCIe SSD • Exporting The Log • Performing A Cryptographic Erase on An NVMe PCIe SSD To perform a physical device task: 1 In the Server Administrator window, under the System tree, expand the Storage tree object to display the storage component objects.
Exporting The Log The export log contains debug information for the PCIe SSD and can be useful when troubleshooting. You can export the reliability log from the Physical Device Available Tasks drop-down list.

7 Controllers This chapter provides information about the supported controllers and controller features in Storage Management.
SAS RAID Controllers The following RAID controllers use Serial Attached SCSI (SAS) technology.
Controller — Supported Stripe Sizes When creating a virtual disk, you must specify the stripe size for the virtual disk. Different controllers have different limitations on the stripe sizes they can support. For information on the supported stripe sizes for a controller, see the virtual disk specifications section for the controller in Supported Features.
• • NOTE: Write-through is the default write policy setting when cluster mode is enabled. Write Cache Enabled Protected — The controller writes data to the write cache before writing data to the physical disk. Because it takes less time to write data to the write cache than it does to a disk, enabling write cache can improve system performance. After data is written to the write cache, the system is free to continue with other operations.
• Default — The disk uses the default write cache mode. • Enabled — Disk Cache Policy is enabled. • Disabled — Disk Cache Policy is disabled. • Inconsistent — The disk cache policy is not uniform across all the physical disks in the virtual disk. For example, if a virtual disk contains three physical disks; the disk cache policy of the first physical disk is Enabled, the second physical disk is Disabled, and the third physical disk is Default.
NOTE: Storage Management only enumerates and provides the PCI slot information for Broadcom SAS 9207-8e and SAS 9300-8e controllers. As Storage Management does not monitor these non-RAID controllers, devices connected to these controllers are not enumerated, alerts are not logged, and SNMP traps are not sent for these controllers.
Property Definition Minimum Required Storport Driver Version Displays the minimum storport driver version required by Storage Management. This property is displayed if the operating system storport driver does not meet the minimum requirement. This option is applicable only on systems running Microsoft Windows operating system. NOTE: To download the latest storport driver, see the Microsoft Knowledge Base article KB943545 at support.microsoft.com.
Property Definition Name Displays the name of the controller. NOTE: For PowerEdge FD332 storage sled, the name is displayed as: • • Single controller — PERC FD33xS (Integrated RAID Controller in Front Chassis Slot , where X displays the controller number and Y displays the front chassis slot number. Dual controller — PERC FD33xD (Integrated RAID Controller in Front Chassis Slot , where X displays the controller number and Y displays the front chassis slot number.
Property Definition Rebuild Rate Rebuild rate is the percentage of resources available on a system dedicated to rebuild a failed disk when necessary. For more information on rebuild rate, see Setting The Rebuild Rate. NOTE: The value for the Revertible Hot Spare operation is the same as the value set for the Rebuild Rate property.
Property Definition Patrol Read Mode Displays the Patrol Read Mode setting for the controller. Possible values are: • • • Auto — Patrol read runs continuously on the system. When one iteration of the patrol read is complete, the next patrol read is scheduled to start within an interval specified by the controller. You do not have the option of manually starting or stopping the Patrol Read in this mode. Manual — Allows you to manually start or stop the patrol read process.
Property Definition NOTE: This is supported only on two controllers H740P and H745PMX. Front Chassis Slot Displays the front chassis slot number. This property is applicable only for PowerEdge FD332 storage sled. For more information on PowerEdge FD332, see the Dell PowerEdge FD332 Owner's Manual at dell.com/ poweredgemanuals. Controller Tasks To execute a controller task: 1 In the Server Administrator window, under the system tree, expand Storage to display the controller objects.
• • Changing The Controller Mode Auto Configure RAID0 Operation Creating A Virtual Disk Does my controller support this feature? See Supported Features. To launch the Create Virtual Disk Express Wizard, select the Create Virtual Disk task. Enabling The Controller Alarm Does my controller support this feature? See Supported Features. To enable the alarm on the controller, select the Enable Alarm task. When enabled, the alarm sounds in the event of a device failure.
On the PERC controllers, the controller firmware also uses the rebuild rate setting to control the system resource allocation for the following tasks: • Performing A Check Consistency • Background Initialization. See Cancelling Background Initialization • Full Initialization. A BIOS setting determines whether a full or fast initialization occurs. See Format, Initialize, Slow And Fast Initialize • Reconfigure.
To Locate Reset Configuration In Storage Management 1 In the Server Administrator window, under the system tree, expand Storage to display the controller objects. 2 Select a controller object. 3 Click Information/Configuration. 4 Select Reset Configuration from the Available Tasks drop-down menu. 5 Click Execute. You can also locate this task from the Change Controller Properties drop-down menu. Exporting The Controller Log File Does my controller support this feature? See Supported Features.
NOTE: This task is not supported on PERC hardware controllers running in HBA mode. NOTE: Foreign Configuration Operations task is available only on PERC 6 and SAS controllers with firmware versions 6.1 and later. A foreign configuration is data residing on physical disks that have been moved from one controller to another. Virtual disks residing on physical disks that have been moved are considered to be a foreign configuration.
Property Definition The foreign configuration may be in degraded or failed state due to any of the following reasons: • • • • • • • Missing physical disk — One of the physical disk(s) in the potential virtual disk is missing or not available. Missing span — One or more spans of a hybrid virtual disk is missing. Stale physical disks — One or more physical disks in the configuration may contain out-of-date data relating to other disks of that virtual disk.
You can import a foreign configuration only if it contains a virtual disk that is either in a Ready or Degraded state. In other words, all of the virtual disk data must be present, but if the virtual disk is using a redundant RAID level, the additional redundant data is not required. For example, if the foreign configuration contains only one side of a mirror in a RAID 1 virtual disk, then the virtual disk is in a Degraded state and can be imported.
Clearing Foreign Configuration Does my controller support this feature? See Supported Features. After moving a physical disk from one controller to another, you may find that the physical disk contains all or some portion of a virtual disk (foreign configuration). You can identify whether a previously used physical disk contains a foreign configuration (virtual disk) by checking the physical disk state.
Property Definition For more information, see Storage Component Severity. Name Displays the name of the physical disk. The name is comprised of the connector number followed by the disk number. State Displays the current state of the physical disk. After Import State Displays the after-import state of the physical disk. The physical disk can be imported in any of the following states: • • • • • Online — The physical disk is part of the imported virtual disk and functions normally.
Property Definition • Used RAID Disk Space Unknown — Storage Management is unable to determine the media type of the physical disk. Displays the amount of the physical disk space that is used by the virtual disks on the controller. This property is not applicable for physical disks attached to non-RAID controllers. In certain circumstances, the Used RAID Disk Space displays a value of zero (0) even though a portion of the physical disk is actually being used. This occurs when the used space is 0.
Setting Background Initialization Rate Does my controller support this feature? See Supported Features. The Set Background Initialization Rate task changes the amount of system resources dedicated to the background initialization task. The background initialization rate, configurable between 0% and 100%, represents the percentage of the system resources dedicated for running the background initialization task.
To Locate Set Check Consistency Rate In Storage Management 1 In the Server Administrator window, under the system tree, expand Storage to display the controller objects. 2 Select a controller object. 3 Click Information/Configuration on the controller Properties page. 4 Select Set Check Consistency Rate from the Available Tasks drop-down menu. 5 Click Execute. You can also locate this task from the Change Controller Properties drop-down menu.
The Set Patrol Read task runs in the background and corrects, when possible. When the Set Patrol Read mode is set to Auto, patrol read is initiated when the controller is idle for a period of time and when no other background tasks are active. In this scenario, the patrol read enhances the system performance as disk errors can be identified and corrected when there is not input/output activity on the disk.
There are certain conditions under which the Patrol Read task cannot be run. To start or stop the Patrol Read Task: Click Start Patrol Read or Stop Patrol Read. NOTE: On PERC 9 family and later of hardware controllers, the Stop Patrol Read task displays: Patrol Read Aborted or Manually Stopped. On controllers prior to PERC 9, the Stop Patrol Read task displays: Patrol Read is Completed. To exit without starting or stopping the Patrol Read, click Go Back to Previous Page.

Tape Drive Properties Property Definition ID Displays the ID of the tape drive. Name Displays the name of the tape drive. Bus Protocol Displays the bus protocol type of the tape drive.
13 RAID Controller Batteries Some RAID controllers have batteries. If the controller has a battery, Storage Management displays the battery under the controller object in the tree view. If there is a power outage, the controller battery preserves data that is in the volatile cache memory (SRAM) but not yet written to disk. The battery is designed to provide a minimum backup of 24 hours. When a RAID controller is first installed in a server, the battery may need charging.
Property Definition When the battery is in Warn mode, the state of the controller is displayed as degraded. NOTE: Warn is available only on SAS controllers with firmware version 6.1 and later. Next Learn Time Displays the number of days and hours left before the controller firmware initiates the next learn cycle. Maximum Learn Delay Displays the maximum number of days and hours that you can delay the battery learn cycle. The controller firmware automatically initiates the battery learn cycle.
14 Physical Disks Or Physical Devices Physical disks or physical devices reside within an enclosure or are attached to the controller. On a RAID controller, physical disks or devices are used to create virtual disks.
For SAS Controllers For SAS controllers, you must: 1 Check the alert log for an alert verifying that the system has identified the new disk. You may receive alert 2052 or 2294.

Property Definition Non-RAID Disk cache policy Displays the cache policy of the NON-RAID disk. For the Non-RAID physical disk the Non-RAID disk cache policy property can be changed to unchanged, enable, or disable. NOTE: This feature is not available from PERC 10 or later. Available Spare Displays the available spare value set for all SSDs (SAS / SATA). New disk will have 100% spare which comes down as per the usage.
NOTE: The Blink and Unblink tasks are only supported for hotswap physical disks (disks that reside in a carrier). When using an Broadcom PCIe U320 controller, the Blink and Unblink tasks apply to physical disks contained in carriers that can be inserted into a server or an enclosure. If the physical disk is not contained in a carrier but is instead designed to be connected with a SCSI cable (typically a ribbon cable), then the Blink and Unblink tasks are disabled.
Select the Cancel Rebuild task to cancel a rebuild that is in progress. If you cancel a rebuild, the virtual disk remains in a Degraded state. The failure of an additional physical disk can cause the virtual disk to fail and may result in data loss. It is recommended that you rebuild the failed physical disk as soon as possible. NOTE: If you cancel the rebuild of a physical disk that is assigned as a hot spare, reinitiate the rebuild on the same physical disk in order to restore the data.

Convert To Non-RAID Disk This task converts a disk to a Non-RAID disk.
15 Virtual Disks A virtual disk refers to a storage created by a RAID controller from one or more physical disks. Although a virtual disk may be created from several physical disks, it is viewed by the operating system as a single disk. Depending on the RAID level used, the virtual disk may retain redundant data if there is a disk failure or have particular performance attributes. NOTE: Virtual disks can only be created on a RAID controller.
Considerations Before Creating Virtual Disks Different controllers have particular characteristics in the way they implement virtual disks. These characteristics may include use of disk space, limitations on the number of virtual disks per controller, and so on. It can be helpful to understand these characteristics before creating virtual disks on the controller.
the physical disks are of equal size. In addition, when the physical disks are of equal size and you use the leftover space for a second virtual disk, this new virtual disk cannot expand to include any physical disks not included in the original virtual disk. • Space allocation when deleting and creating virtual disks on controllers — When you delete a virtual disk, you free up or make available space on the physical disks that was being used by the deleted virtual disk.
the number of total stripes and spans is limited, the number of physical disks that can be used is also limited. The limitations on stripes and spans affect the possibilities for concatenation and RAID levels as follows: • Maximum number of spans affects RAID 10, RAID 50, and RAID 60. • Maximum number of stripes affects RAID 0, RAID 5, RAID 50, RAID 6, and RAID 60. • Number of physical disks in a mirror is always 2. This property affects RAID 1 and RAID 10.
Creating Virtual Disks Does my controller support this feature? See Supported Features. In order to implement RAID functions, you must create a virtual disk. A virtual disk refers to storage created by a RAID controller from one or more physical disks. Although a virtual disk may be created from several physical disks, it is seen by the operating system as a single disk. Before creating a virtual disk, you should be familiar with the information in Considerations Before Creating Virtual Disks.

If you have a redundant virtual disk, you can reconstruct the contents of a failed physical disk onto a new disk or a hot spare. A rebuild can take place during normal operation, but it degrades performance. A global hot spare drive can be part of different RAID level Virtual drives rebuilding operation on SWRAID controllers. Managing Virtual Disk Bad Block Management Virtual disk bad blocks are bad blocks on one or more member physical disks.
RAID Level Virtual Disk State Scenario Result RAID 6 Degraded (two failed/missing physical disks) One bad block on a physical disk. The controller cannot regenerate data from the peer disks. This results in a virtual disk bad block. RAID 6 Ready One bad block on a physical disk. The controller regenerates data from peer disks and sends a Write to the bad block. The disk then remaps the Logical Block Addressing (LBA) to another physical location. The problem is resolved.
Property Definition — Warning/Non-critical — Critical/Failure/Error For more information, see Storage Component Severity. Name Displays the virtual disk name. For all the disk which are not part of the virtual disk will display as NON-Raid Disks for systems running on Enhanced HBA mode. Hot-plugged in disks will also come up as NONRAID disks. State Displays the status of the virtual disk. Possible values are: • • • • • • • • • • • • Ready — The virtual disk is functioning normally.
Property Definition The algorithm for calculating the virtual disk size rounds a value of 0.005 or less, down to 0.00 and a value between 0.006 and 0.009, up to 0.01. For example, a virtual disk size of 819.725 is rounded down to 819.72. A virtual disk size of 819.726 is rounded up to 819.73. Device Name Displays the operating system device name for this object. Bus Protocol Displays the technology that the physical disks included in the virtual disk are using.

The Restore Dead Segments task recovers data from a RAID-5 virtual disk that has been corrupted. The Restore Dead Segments task attempts to reconstruct data from the corrupt portion of a physical disk included in a RAID-5 virtual disk. The Restore Dead Segments task uses the parity or redundant information to reconstruct the lost data. This task is not always able to recover lost data. Deleting Data On the Virtual Disk Does my controller support this feature? See Supported Features.
Renaming A Virtual Disk Does my controller support this feature? See Supported Features. The Rename task enables you to change name of the virtual disk. Canceling A Rebuild Does my controller support this feature? See Supported Features. Select the Cancel Rebuild task to cancel a rebuild that is in progress. If you cancel a rebuild, the virtual disk remains in a Degraded state. The failure of an additional physical disk can cause the virtual disk to fail and may result in data loss.
Encrypting A Virtual Disk Does my controller support this feature? See Supported Features. The Encrypt Virtual Disk task encrypts an unencrypted virtual disk.
• 5 Select RAID 50 to implement striping across more than one span of physical disks. RAID 50 groups n*s disks as one large virtual disk with a capacity of s*(n-1) disks, where s is the number of spans and n is the number of disks within each span. • Select RAID 60 to implement striping across more than one RAID 6 span. RAID 60 Groups n*s disks as one large virtual disk with a capacity of s*(n-2) disks, where s is the number of spans and n is the number of disks within each span.
NOTE: This task is not supported on PERC hardware controllers running in HBA mode. To create a virtual disk using the Create Virtual Disk Advanced Wizard: 1 On the left-hand side of the Server Administrator page, expand Storage. 2 Click on the . 3 Click on Virtual Disks. The Virtual Disk(s) on Controller page is displayed. 4 Click Go to the Create Virtual Disk Wizard. The Create Virtual Disk Wizard (Step 1) page is displayed.
◦ Across connectors in the enclosure that are not at the same level but of same size. ◦ Across enclosures connected to the same connector and to a disk of the same size. ◦ Within the enclosure with a physical disk of acceptable size difference. ◦ Across connectors at the same level of enclosure and of acceptable size difference. ◦ Across connectors in the enclosure that are not at the same level of the enclosure but with a physical disk of acceptable size difference.
• Physical disk 0:3:0 • Physical disk 0:4:0 Physical Disks Selected The Physical Disks Selected section of the page displays the disks you have chosen. In this example, two disks are selected. • Physical disk 0:0:0 • Physical disk 0:1:0 Each RAID level has specific requirements for the number of disks that must be selected. RAID 10, RAID 50, and RAID 60 also have requirements for the number of disks that must be included in each stripe or span.
The virtual disk size must be within the minimum and maximum values displayed near the Size field. In some cases, the virtual disk is slightly larger than the size you specify. The Create Virtual Disk Wizard adjusts the size of the virtual disk to avoid rendering a portion of the physical disk space unusable. NOTE: If a physical disk is receiving a SMART alert, it cannot be used in a virtual disk.
Span Edit In the edit mode, you cannot alter the number of physical disks per span. If there are enough available physical disks, you can reduce or increase the number of spans. You can also alter the contents of a span by removing the span and selecting a new physical disk to comprise that span. To successfully create a virtual disk, a minimum of two spans must exist always. NOTE: If you select Span Edit, Intelligent Mirroring that is already been applied becomes invalid.
The virtual disk reconfigure Step 2 page enables you to select the RAID level and size for the reconfigured virtual disk. The Expand Capacity option appears only for PERC H730P MX and PERC H745P MX controllers with firmware version 7.1 or later. If you selected Expand Capacity in Step 1, this page allows you to expand the capacity of the virtual disk.
To Reconfigure A Virtual Disk Expand Virtual Disk Capacity - Step 2 of 3 NOTE: For RAID 10 partial virtual disks, there are only two methods to increase the disk size or capacity: 1 • Expanding the capacity by increasing the percentage value. • Adding disks into the original RAID 10 virtual disk. Enter the percentage of the free disk size available by which you want to expand the virtual disk capacity. The page displays the maximum free size available and the description of the selected RAID level.
The Slow Initialize task initializes one physical disk at a time. Each physical disk displays the Clear state while being initialized. While the physical disk is in the Clear state, the Cancel Clear physical disk task is available. Performing a Cancel Clear task on the physical disk causes the Slow Initialize task to be canceled for the entire virtual disk and all member physical disks.
• If you delete a virtual disk and immediately create a new virtual disk with all the same characteristics as the one that was deleted, the controller recognizes the data as if the first virtual disk were never deleted. In this situation, if you don't want the old data after recreating a new virtual disk, reinitialize the virtual disk. • On deleting NON-Raid Disks from the Virtual Disk tab for systems running on Enhanced HBA mode, the corresponding physical disk displays as Ready State.
Changing The Read, Write, Or Disk Cache Policy Of A Virtual Disk 1 Select the new policy from the Read Policy, Write Policy, and Disk Cache Policy drop-down menus. 2 Click Apply Changes. To exit without changing the virtual disk policy, click Go Back To Virtual Disk Page. To Locate Change Policy In Storage Management 1 In the Server Administrator window, under the system tree, expand Storage to display the controller objects. 2 Expand a Controller object. 3 Select the Virtual Disks object.
Use the Unmirror task to separate mirrored data and restore one half of the mirror to free space. Unmirroring a RAID 1 or RAID 1concatenated virtual disk results in a single, nonredundant concatenated virtual disk. Unmirroring a RAID 10 virtual disk results in a single, nonredundant RAID 0 (striped) virtual disk. Data is not lost during this operation. NOTE: On systems running Linux operating systems, an Unmirror cannot be performed on a mounted virtual disk. To Unmirror Click Unmirror.
Unassigning A Dedicated Hot Spare 1 Select the disk in the Disks currently configured as dedicated hot spare table to unassign it. On some controllers, more than one disk can be selected. Clicking the disk removes the disk from the Disks currently configured as dedicated hot spare table and returns it to the Connector (channel or port) table. 2 Click Apply Changes when ready.
NOTE: For PERC H330, H730, H730P, H730P MX, H740P, H745P MX and H840 controllers, if any of the drives you selected is in the spun down state, the following message is displayed: The below listed physical drive(s) are in the spun down state. Executing this task on these drive(s) takes additional time, because the drive(s) need to spun up. The message displays the ID(s) of the spun down drive(s).
16 Moving Physical And Virtual Disks From One System To Another This section describes how to move physical and virtual disks from one system to another. Topics: • Required Conditions • Migrating SAS Virtual Disks To Another System Required Conditions SAS Controllers Virtual disks can only be migrated to a controller that is using the same technology. For example, virtual disks on a SAS controller must be migrated to a SAS controller.
17 Protecting Your Virtual Disk With A Hot Spare When you create a virtual disk using a RAID controller, it enables the system to continue functioning even during a disk failure. This feature can be enabled by assigning a hot spare to the virtual disk. When a disk fails, the redundant data is rebuilt onto the hot spare without interrupting system operations.
Property Definition Severity Level Displays the severity level you want to assign to the generated alert, if this policy is violated. NOTE: The status of the virtual disk is determined by the severity level you specify for this policy. Resetting The Hot Spare Protection Policy Clear RAID Layout to reset the dedicated hot spare protection policy. Global Hot Spare Protection Policy Table 35.
18 Troubleshooting This section contains troubleshooting procedures for common situations as well as for specific problems.

NOTE: You can verify which firmware and drivers are installed by selecting the Storage object in the tree view and clicking Information/Configuration. You can also check the Alert Log for alerts relating to unsupported firmware and driver versions. It is also recommended to obtain and apply the latest server system BIOS on a periodic basis to benefit from the most recent improvements. For more information on server system BIOS, see the system documentation.
Replacing A Failed Physical Disk That Is Part Of A Non-Redundant Virtual Disk If the failed physical disk is part of a nonredundant virtual disk (such as RAID 0), then the failure of a single physical disk causes the entire virtual disk to fail. To proceed, you need to verify when a backup was taken, and if there is any new data that has been written to the virtual disk since that time. If you have backed up recently and there is no new data on the disks that would be missed, you can restore from backup.
Resolving Microsoft Windows Upgrade Problems If you upgrade the Microsoft Windows operating system on a server, you may find that Storage Management no longer functions after the upgrade. The installation process installs files and updates registry entries on the server that are specific to the operating system. Changing the operating system can disable Storage Management. To avoid this problem, you should uninstall Storage Management before upgrading.
The rebuild may also report sense key errors. In this situation, take the following actions to restore the maximum data possible: 1 Back up the degraded virtual disk onto a fresh (unused) tape drive. • If the backup is successful — If the backup completes successfully, then the user data on the virtual disk has not been damaged. In this case, you can continue with step 2.
Problems Associated With Using The Same Physical Disks For Both Redundant And Non-Redundant Virtual Disks When creating virtual disks, you should avoid using the same physical disks for both redundant and nonredundant virtual disks. This applies to all controllers. Using the same physical disks for both redundant and nonredundant virtual disks can result in unexpected behavior including data loss.
This damage is discovered when the controller performs an operation that requires scanning the disk. Examples of operations that may result in these alerts are as follows: • Consistency check • Rebuild • Virtual disk format • I/O If you receive alerts 2146 through 2150 as the result of performing a rebuild or while the virtual disk is in a degraded state, then data cannot be recovered from the damaged disk without restoring from the backup.
A Corrupt Disk Or Drive Message Suggests Running Autocheck During A Reboot You can ignore the message and perform autocheck. The reboot completes after autocheck is completed. Depending on the size of your system, it may take about 10 minutes. Erroneous Status And Error Messages After A Windows Hibernation Activating the Windows hibernation feature may cause Storage Management to display erroneous status information and error messages.
Reconfiguring A Virtual Disk Displays Error In Mozilla Browser When reconfiguring a virtual disk using the Mozilla browser, the following error message may display: Although this page is encrypted, the information you have entered is to be sent over an unencrypted connection and could easily be read by a third party.
