Planning a Subsystem 1 This chapter provides information that helps you plan how to configure the storage array subsystem. This chapter focuses on the technical terms and knowledge needed to plan and implement storage subsystems. Note: This chapter frequently references the command line interface (CLI). For the complete syntax and descriptions of the CLI commands, see the HP StorageWorks HSG60 and HSG80 Array Controller and Array Controller Software Command Line Interface Reference Guide.
Planning a Subsystem Defining Subsystems This section describes the terms this controller and other controller. It also presents graphics of the Model 2200 and BA370 enclosures. Note: The HSG80 controller uses the BA370 or Model 2200 enclosure. Controller Designations A and B The terms A, B, “this controller,” and “other controller,” respectively are used to distinguish one controller from another in a two-controller (also called dual-redundant) subsystem.

These designations are a shortened form of “this controller” and “other controller.

Planning a Subsystem What is Failover Mode? Failover is a way to keep the storage array available to the host if one of the controllers becomes unresponsive. A controller can become unresponsive because of a controller hardware failure or, in multiple-bus mode only, due to a failure of the link between host and controller or host-bus adapter. Failover keeps the storage array available to the hosts by allowing the surviving controller to take over total control of the subsystem.
Planning a Subsystem At any time, host port 1 is active on only one controller, and host port 2 is active on only one controller. The other ports are in standby mode. In normal operation, both host port 1 on controller A and host port 2 on controller B are active. A representative configuration is shown in Figure 8. The active and standby ports share port identity, enabling the standby port to take over for the active one.

Planning a Subsystem In multiple-bus failover mode, you can specify which units are normally serviced by a specific controller of a controller pair. Units can be preferred to one controller or the other by the PREFERRED_PATH switch of the ADD UNIT (or SET unit) command. For example, use the following command to prefer unit D101 to “this controller”: SET D101 PREFERRED_PATH=THIS_CONTROLLER Note: This is an initial preference, which can be overridden by the hosts.

Planning a Subsystem Selecting a Cache Mode The cache module supports read, read-ahead, write-through, and write-back caching techniques. The cache technique is selected separately for each unit. For example, you can enable only read and write-through caching for some units while enabling only write-back caching for other units. Read Caching When the controller receives a read request from the host, it reads the data from the disk drives, delivers it to the host, and stores the data in its cache module.
Planning a Subsystem Write-Through Caching Write-through caching is enabled when write-back caching is disabled. When the controller receives a write request from the host, it places the data in its cache module, writes the data to the disk drives, then notifies the host when the write operation is complete. This process is called write-through caching because the data actually passes through—and is stored in—the cache memory on its way to the disk drives. 40 HSG80 ACS Solution Software V8.
Planning a Subsystem Enabling Mirrored Caching In mirrored caching, half of each controller’s cache mirrors the companion controller’s cache, as shown in Figure 11. The total memory available for cached data is reduced by half, but the level of protection is greater.
Planning a Subsystem The CCL does the following: ■ Allows the RAID Array to be recognized by the host as soon as it is attached to the SCSI bus and configured into the operating system. ■ Serves as a communications device for the HS-Series Agent. The CCL identifies itself to the host by a unique identification string. In dual-redundant controller configurations, the commands described in the following sections alter the setting of the CCL on both controllers. The CCL is enabled only on host port 1.
Planning a Subsystem Enabling/Disabling CCL in SCSI-3 Mode The CCL is enabled all the time. There is no option to enable/disable. Determining Connections The term “connection” applies to every path between a Fibre Channel adapter in a host computer and an active host port on a controller. Note: In ACS V8.8-1, the maximum number of supported connections is 96. Naming Connections It is highly recommended that you assign names to connections that have meaning in the context of your particular configuration.
Planning a Subsystem Numbers of Connections The number of connections resulting from cabling one adapter into a switch or hub depends on failover mode and how many links the configuration has: 44 ■ If a controller pair is in transparent failover mode and the port 1 link is separate from the port 2 link (that is, ports 1 of both controllers are on one loop or fabric, and port 2 of both controllers are on another), each adapter has one connection, as shown in Figure 12.

Planning a Subsystem Assigning Unit Numbers The controller keeps track of the unit with the unit number. The unit number can be from 0–199 prefixed by a D, which stands for disk drive. A unit can be presented as different LUNs to different connections.
Planning a Subsystem For example, if all host connections use the default offset values, unit D2 is presented to a port 1 host connection as LUN 2 (unit number of 2 minus offset of 0). Unit D102 is presented to a port 2 host connection as LUN 2 (unit number of D102 minus offset of 100). Figure 15 shows how units are presented as different LUNs, depending on the offset of the host.
Planning a Subsystem An additional factor to consider when assigning unit numbers and offsets is SCSI version. If the SCSI_VERSION switch of the SET THIS_CONTROLLER/OTHER_CONTROLLER command is set to SCSI-3, the CCL is presented as LUN 0 to every connection, superseding any unit assignments. The interaction between SCSI version and unit numbers is explained further in the next section. In addition, the access path to the host connection must be enabled for the connection to access the unit.
Planning a Subsystem Assigning Unit Numbers Depending on SCSI_VERSION The SCSI_VERSION switch of the SET THIS_CONTROLLER/OTHER_CONTROLLER command determines how the CCL is presented. There are two choices: SCSI-2 and SCSI-3. The choice for SCSI_VERSION affects how certain unit numbers and certain host connection offsets interact. Assigning Host Connection Offsets and Unit Numbers in SCSI-3 Mode If SCSI_VERSION is set to SCSI-3, the CCL is presented as LUN 0 to all connections.
Planning a Subsystem Table 3 summarizes the recommendations for unit assignments based on the SCSI_VERSION switch. Table 3: Unit assignments and SCSI_VERSION SCSI_VERSION 52 Offset Unit Assignment What the connection sees LUN 0 as SCSI-2 Divisible by 10 At offsets Unit whose number matches offset SCSI-3 Divisible by 10 Not at offsets CCL HSG80 ACS Solution Software V8.
Planning a Subsystem What is Selective Storage Presentation? Selective Storage presentation is a feature of the HSG80 controller that enables you to control the allocation of storage space and shared access to storage across multiple hosts. This is also known as Restricting Host Access. In a subsystem that is attached to more than one host or if the hosts have more than one adapter, it is possible to reserve certain units for the exclusive use of certain host connections.
Planning a Subsystem Note: These techniques also work for a single controller. Restricting Host Access by Separate Links In transparent failover mode, host port 1 of controller A and host port 1 of controller B share a common Fibre Channel link. Host port 2 of controller A and host port 2 of controller B also share a common Fibre Channel link.

Planning a Subsystem For example: In Figure 17, restricting the access of unit D101 to host 3, the host named BROWN can be done by enabling only the connection to host 3. Enter the following commands: SET D101 DISABLE_ACCESS_PATH=ALL SET D101 ENABLE_ACCESS_PATH=BROWN1B2 If the storage subsystem has more than one host connection, carefully specify the access path to avoid providing undesired host connections access to the unit.
Planning a Subsystem Restricting Host Access by Offsets Offsets establish the start of the range of units that a host connection can access. For example: In Figure 16, assume both host connections on port 2 (connections BLACK1B2 and BROWN1B2) initially have the default port 2 offset of 100. Setting the offset of connection BROWN1B2 to 120 presents unit D120 to host BROWN as LUN 0. SET BROWN1B2 UNIT_OFFSET=120 Host BROWN cannot see units lower than its offset, so it cannot access units D100 and D101.

Planning a Subsystem multiple-bus failover to work. For most operating systems, it is desirable to have all connections to the host enabled.
Planning a Subsystem For example: In Figure 17, assume all host connections initially have the default offset of 0. Giving all connections access to host BLUE, an offset of 120 presents unit D120 to host BLUE as LUN 0. Enter the following commands: SET BLUE1A1 UNIT_OFFSET=120 SET BLUE1B1 UNIT_OFFSET=120 SET BLUE2A2 UNIT_OFFSET=120 SET BLUE2B2 UNIT_OFFSET=120 Host BLUE cannot see units lower than its offset, so it cannot access any other units.
Planning a Subsystem In multiple-bus failover mode, each of the host ports has its own port ID: ■ Controller B, port 1—worldwide name + 1, for example 5000-1FE1-FF0C-EE01 ■ Controller B, port 2—worldwide name + 2, for example 5000-1FE1-FF0C-EE02 ■ Controller A, port 1—worldwide name + 3, for example 5000-1FE1-FF0C-EE03 ■ Controller A, port 2—worldwide name + 4, for example 5000-1FE1-FF0C-EE04 Use the CLI command, SHOW THIS_CONTROLLER/OTHER_CONTROLLER to display the subsystem’s worldwide name.

If you attempt to set the subsystem worldwide name to a name other than the one that came with the subsystem, the data on the subsystem is not accessible.
Planning Storage Configurations 2 This chapter provides information to help you plan the storage configuration of your subsystem. Storage containers are individual disk drives (JBOD), storageset types (mirrorsets, stripesets, and so on), and/or partitioned drives. Use the guidelines found in this section to plan the various types of storage containers needed.
Planning Storage Configurations Where to Start The following procedure outlines the steps to follow when planning your storage configuration. See Appendix A to locate the blank templates for keeping track of the containers being configured. 1. Determine your storage requirements. Use the questions in "Determining Storage Requirements", page 66, to help you. 2. Review configuration rules. See "Configuration Rules for the Controller", page 67. 3.
Planning Storage Configurations — Use the Command Line Interpreter (CLI) commands. This method allows you flexibility in defining and naming your storage containers. See the HP StorageWorks HSG60 and HSG80 Array Controller and Array Controller Command Line Interface Reference Guide. HSG80 ACS Solution Software V8.
Planning Storage Configurations Determining Storage Requirements It is important to determine your storage requirements.
Planning Storage Configurations Configuration Rules for the Controller The following list defines maximum configuration rules for the controller: ■ 128 visible LUNs/200 assignable unit numbers — In SCSI-2 mode, if the CCL is enabled, the result is 127 visible LUNs and one CCL. — In SCSI-3 mode, if the CCL is enabled, the result is 126 visible LUNs and two CCLs.
Planning Storage Configurations Tip: If you are redeploying disks that have been operating under a prior version of ACS into a newly established container, as a best practice, always initialize the devices and the new container before proceeding with subsystem activities to avoid operational and performance issues. 68 HSG80 ACS Solution Software V8.
Planning Storage Configurations Addressing Conventions for Device PTL The HSG80 controller has six SCSI device ports, each of which connects to a SCSI bus. In dual-controller subsystems, these device buses are shared between the two controllers. (The StorageWorks Command Console calls the device ports “channels.”) The standard BA370 enclosure provides a maximum of four SCSI target identifications (ID) for each device port. If more target IDs are needed, expansion enclosures can be added to the subsystem.
Planning Storage Configurations ■ L—Designates the logical unit (LUN) of the device. For disk devices the LUN is always 0. 1 02 Disk 10200 LUN 00 Target 02 Port 1 Figure 21: PTL naming convention The controller can either operate with a BA370 enclosure or with a Model 2200 controller enclosure combined with Model 4214R, Model 4254, Model 4310R, Model 4350R, Model 4314R, or Model 4354R disk enclosures. The controller operates with BA370 enclosures that are assigned ID numbers 0, 2, and 3.
Planning Storage Configurations Examples - Model 2200 Storage Maps, PTL Addressing The Model 2200 controller enclosure can be combined with the following: ■ Model 4214R disk enclosure—Ultra2 SCSI with 14 drive bays, single-bus I/O module. ■ Model 4254 disk enclosure—Ultra2 SCSI with 14 drive bays, dual-bus I/O module. Note: The Model 4214R uses the same storage maps as the Model 4314R, and the Model 4254 uses the same storage maps as the Model 4354R disk enclosures.
Planning Storage Configurations ■ Model 4354R disk enclosure—Ultra3 SCSI with 14 drive bays, dual-bus I/O module. Table 7 shows the addresses for each device in a three-shelf, dual-bus configuration. A maximum of three Model 4354R disk enclosures can be used with each Model 2200 controller enclosure.

Planning Storage Configurations Choosing a Container Type Different applications may have different storage requirements. You probably want to configure more than one kind of container within your subsystem. In choosing a container, you choose between independent disks (JBODs) or one of several storageset types, as shown in Figure 23. The independent disks and the selected storageset may also be partitioned. The storagesets implement RAID (Redundant Array of Independent Disks) technology.
Planning Storage Configurations Table 8 compares the different kinds of containers to help you determine which ones satisfy your requirements.
Planning Storage Configurations Creating a Storageset Profile Creating a profile for your storagesets, partitions, and devices can simplify the configuration process. Filling out a storageset profile helps you choose the storagesets that best suit your needs and to make informed decisions about the switches you can enable for each storageset or storage device that you configure in your subsystem. For an example of a storageset profile, see Table 9.

Planning Storage Configurations Planning Considerations for Storageset This section contains the guidelines for choosing the storageset type needed for your subsystem: ■ "Stripeset Planning Considerations", page 82 ■ "Mirrorset Planning Considerations", page 84 ■ "RAIDset Planning Considerations", page 86 ■ "Striped Mirrorset Planning Considerations", page 88 ■ "Storageset Expansion Considerations", page 90 ■ "Partition Planning Considerations", page 90 Stripeset Planning Considerations Stripes
Planning Storage Configurations The relationship between the chunk size and the average request size determines if striping maximizes the request rate or the data-transfer rate. You can set the chunk size or use the default setting (see "Chunk Size", page 95, for information about setting the chunk size). Figure 25 shows another example of a three-member RAID 0 stripeset. A major benefit of striping is that it balances the I/O load across all of the disk drives in the storageset.
Planning Storage Configurations ■ Striping does not protect against data loss. In fact, because the failure of one member is equivalent to the failure of the entire stripeset, the likelihood of losing data is higher for a stripeset than for a single disk drive. For example, if the mean time between failures (MTBF) for a single disk is l hour, then the MTBF for a stripeset that comprises N such disks is l/N hours.

Planning Storage Configurations ■ You can configure up to a maximum of 20 RAID 3/5 mirrorsets per controller or pair of dual-redundant controllers. Each mirrorset may contain up to 6 members. Refer to "Configuration Rules for the Controller", page 67, for detailed information on maximum numbers. 30 RAID 3/5 and RAID 1 mirrorsets are permitted, however, there is limit of no more than 20 RAID 3/5 mirrorsets in such a configuration. ■ Both write-back cache modules must be the same size.
Planning Storage Configurations Virtual disk Operating system view Disk 1 Block 0 Block 5 Block 10 Block 15 Block 0 Block 1 Block 2 Block 3 Block 4 Block 5 etc.
Planning Storage Configurations ■ A RAIDset must include at least 3 disk drives, but no more than 14. ■ A storageset should only contain disk drives of the same capacity. The controller limits the capacity of each member to the capacity of the smallest member in the storageset. Thus, if you combine 9 GB disk drives with 4 GB disk drives in the same storageset, you waste 5 GB of capacity on each 9 GB member.

Under normal circumstances, a single disk drive failure has very little effect on performance.
Planning Storage Configurations Plan the mirrorset members, and plan the stripeset that contains them. Review the recommendations in "Planning Considerations for Storageset", page 82, and "Mirrorset Planning Considerations", page 84. Storageset Expansion Considerations Storageset Expansion allows for the joining of two of the same kind of storage containers by concatenating RAIDsets, stripesets, or individual disks, thereby forming a larger virtual disk which is presented as a single unit.
Planning Storage Configurations unpartitioned storageset or device. Partitions are separately addressable storage units; therefore, you can partition a single storageset to service more than one user group or application. Defining a Partition Partitions are expressed as a percentage of the storageset or single disk unit that contains them: ■ Mirrorsets and single disk units—the controller allocates the largest whole number of blocks that are equal to or less than the percentage you specify.
Planning Storage Configurations Changing Characteristics Through Switches CLI command switches allow you another level of command options. There are three types of switches that modify the storageset and unit characteristics: ■ Storageset switches ■ Initialization switches ■ Unit switches The following sections describe how to enable/modify switches. They also contain a description of the major CLI command switches.
Planning Storage Configurations Specifying Storageset and Partition Switches The characteristics of a particular storageset can be set by specifying switches when the storageset is added to the controllers’ configuration. Once a storageset has been added, the switches can be changed by using a SET command. Switches can be set for partitions and the following types of storagesets: ■ RAIDset ■ Mirrorset Stripesets have no specific switches associated with their ADD and SET commands.
Planning Storage Configurations Partition Switches The following switches are available when creating a partition: ■ Size ■ Geometry For details on the use of these switches, refer to CREATE_PARTITION command in the HP StorageWorks HSG60 and HSG80 Array Controller and Array Controller Command Line Interface Reference Guide. 94 HSG80 ACS Solution Software V8.
Planning Storage Configurations Specifying Initialization Switches Initialization switches set characteristics for established storagesets before they are made into units. The following kinds of switches effect the format of a disk drive or storageset: ■ Chunk Size (for stripesets and RAIDsets only) ■ Save Configuration ■ Destroy/Nodestroy ■ Geometry Each of these switches is described in the following sections.
Planning Storage Configurations Increasing the Request Rate A large chunk size (relative to the average request size) increases the request rate by enabling multiple disk drives to respond to multiple requests. If one disk drive contains all of the data for one request, then the other disk drives in the storageset are available to handle other requests. Thus, separate I/O requests can be handled in parallel, which increases the request rate. This concept is shown in Figure 32.
Planning Storage Configurations ■ If you have mostly sequential reads or writes (like those needed to work with large graphic files), make the chunk size for RAID 0 and RAID 0+1 a small number (for example: 67 sectors). For RAID 5, make the chunk size a relatively large number (for example: 253 sectors). Table 10 shows a few examples of chunk size selection.
Planning Storage Configurations Note: HP recommends that you DO NOT use SAVE_CONFIGURATION on every unit and device on the controller. Destroy/Nodestroy Specify whether to destroy or retain your data and metadata when a disk is initialized after it has been used in a mirrorset or as a single-disk unit. Note: The DESTROY and NODESTROY switches are only valid for mirrorsets and striped mirrorsets. ■ DESTROY (default) overwrites your data and forced-error metadata when a disk drive is initialized.
Planning Storage Configurations Specifying Unit Switches Several switches control the characteristics of units. The unit switches are described under the SET unit-number command in the HP StorageWorks HSG60 and HSG80 Array Controller and Array Controller Command Line Interface Reference Guide. One unit switch, ENABLE/DISABLE_ACCESS_PATH, determines which host connections can access the unit, and it is described in the larger topic of matching units to specific hosts.
Planning Storage Configurations Creating Storage Maps Configuring a subsystem is easier if you know how the storagesets, partitions, and JBODs correspond to the disk drives in your subsystem. You can more easily see this relationship by creating a hardcopy representation, also known as a storage map. To make a storage map, fill out the templates provided in Appendix A as you add storagesets, partitions, and JBOD disks to the configuration and assign them unit numbers.
Planning Storage Configurations Example Storage Map–Model 4310R Disk Enclosure Table 11 shows an example of four Model 4310R disk enclosures (single-bus I/O). ■ Unit D100 is a 4-member RAID 3/5 storageset named R1. R1 consists of Disk10000, Disk20000, Disk30000, and Disk40000. ■ Unit D101 is a 2-member striped mirrorset named S1. S1 consists of M1 and M2: — M1 is a 2-member mirrorset consisting of Disk10100 and Disk20100. — M2 is a 2-member mirrorset consisting of Disk30100 and Disk40100.

Preparing the Host System 3 This chapter describes how to prepare your HP-UX host computer to accommodate the HSG80 controller storage subsystem. The following information is included in this chapter: ■ "Installing RAID Array Storage System", page 106 ■ "Making a Physical Connection", page 110 ■ "Configuring HP-UX File System", page 115 Refer to Chapter 4 for instructions on how to install and configure the HSG Agent. The Agent for HSG is operating system-specific and polls the storage.
Preparing the Host System Installing RAID Array Storage System WARNING: A shock hazard exists at the backplane when the controller enclosure bays or cache module bays are empty. Be sure the enclosures are empty, then mount the enclosures into the rack. DO NOT use the disk enclosure handles to lift the enclosure. The handles cannot support the weight of the enclosure. Only use these handles to position the enclosure in the mounting brackets.
Preparing the Host System 5. Install the elements. Install the disk drives. Make sure you install blank panels in any unused bays. Fibre Channel cabling information is shown to illustrate supported configurations. In a dual-bus disk enclosure configuration, disk enclosures 1, 2, and 3 are stacked below the controller enclosure—two SCSI Buses per enclosure (see Figure 33).

Preparing the Host System For native HP HBAs, follow the instructions that came with your adapter. Connecting to Your Host System To connect to your host system, perform the following steps: 1. Shut down the HP System. Ensure that all power switches on the array controller and the host computer system are in the OFF position. 2. Connect an FC cable between the FC adapter connector on the back of the HP system and a port on the HP StorageWorks FC switch. 3.
Preparing the Host System 6. Turn on the power to the HP system, but do not boot the system. 7. Use the CLI to configure your array controller if it is not yet configured. 8. Boot the system. During the boot process, device special files are created for each logical unit configured on the array controller, and a Logical Unit Number (LUN) is assigned to each storageset configured on the array controller.

Preparing the Host System Configuring HP-UX File System The HP-UX Operating System has now been modified to communicate with the RAID Array Controller. Enable Volume Set Addressing for HP Host Mode HP systems require volume set addressing in order to present more than eight LUNs to the host. The new host port mode is HP_VSA. In order to use the RAID Array from the HP system, perform the following steps: 1. Create new virtual disks on your RAID Array and assign LUN IDs to each virtual disk created.
Preparing the Host System 2. Create a directory for the volume group. This is located in the /dev directory. Enter the following command to verify which volume groups exist. # Is /dev You see a directory similar to the one shown below. From the above list, the only volume group that exists is vg00. For the purpose of this example, vg01 has been created. 3. Enter the following command to make the directory vg01: # mkdir /dev/vg01 Note: The standard HP-UX kernel supports vg00 to vg09.

FC Configuration Procedures 5 This chapter describes procedures to configure a subsystem that uses Fibre Channel (FC) fabric topology. In fabric topology, the controller connects to its hosts through switches.
FC Configuration Procedures Establishing a Local Connection A local connection is required to configure the controller until a command console LUN (CCL) is established using the CLI. Communication with the controller can be through the CLI or SWCC. The maintenance port, shown in Figure 40, provides a way to connect a maintenance port. The maintenance port can be an EIA-423 compatible terminal or a computer running a terminal emulator program. The maintenance port accepts a standard RS-232 jack.
FC Configuration Procedures Setting Up a Single Controller Powering On and Establishing Communication 1. Connect the computer or terminal to the controller, as shown in Figure 40. The connection to the computer is through the COM1 or COM2 port. 2. Turn on the computer or terminal. 3. Apply power to the storage subsystem. 4. Verify that the computer or terminal is configured as follows: — 9600 baud — 8 data bits — 1 stop bit — no parity — no flow control 5. Press Enter.

FC Configuration Procedures When FRUTIL asks if you intend to replace the battery, answer Y: Do you intend to replace this controller's cache battery? Y/N [N] Y FRUTIL prints out a procedure, but does not give you a prompt. Ignore the procedure and press Enter. 12. Set up any additional optional controller settings, such as changing the CLI prompt.
FC Configuration Procedures 14. Verify node ID, allocation class, SCSI version, failover mode, identifier, and port topology. The following display is a sample result of a SHOW THIS command, with the areas of interest in bold. Controller: HSG80 ZG94214134 Software V8.
FC Configuration Procedures 15. Turn on the switches if not done previously. If you want to communicate with the FC switches through Telnet, set an IP address for each switch. See the manuals that came with the switches for details. Plugging in the FC Cable and Verifying Connections 16. Plug the FC cable from the first host adapter into the switch. Enter a SHOW CONNECTIONS command to view the connection table: SHOW CONNECTIONS The first connection has one or more entries in the connection table.
FC Configuration Procedures Verifying Installation To verify installation for your HP-UX host, enter the following command: SHOW DEVICES HSG80 ACS Solution Software V8.
FC Configuration Procedures Configuring Devices The disks on the device bus of the HSG80 can be configured manually or with the CONFIG utility. The CONFIG utility is easier. Invoke CONFIG with the following command: RUN CONFIG WARNING: HP recommends that you use the CONFIG utility only at reduced I/O loads. The CONFIG utility takes about two minutes to discover and to map the configuration of a completely populated storage system. 168 HSG80 ACS Solution Software V8.
FC Configuration Procedures Configuring Storage Containers For a technology refresher on this subject, refer to "Choosing a Container Type", page 78. In choosing a container, you choose between independent disks (JBODs) or one of several storageset types, as shown in Figure 43. The independent disks and the selected storageset may also be partitioned.
FC Configuration Procedures Configuring a Stripeset 1. Create the stripeset by adding its name to the controller's list of storagesets and by specifying the disk drives it contains. Use the following syntax: ADD STRIPESET STRIPESET-NAME DISKNNNNN DISKNNNNN....... 2. Initialize the stripeset, specifying any desired switches: INITIALIZE STRIPESET-NAME SWITCHES See "Specifying Initialization Switches", page 95, for a description of the initialization switches. 3.
FC Configuration Procedures 3. Verify the mirrorset configuration: SHOW MIRRORSET-NAME 4. Assign the mirrorset a unit number to make it accessible by the hosts. See "Assigning Unit Numbers and Unit Qualifiers", page 175. For example: The commands to create Mirr1, a mirrorset with two members (DISK10000 and DISK20000), and to initialize it using default switch settings: ADD MIRRORSET MIRR1 DISK10000 DISK20000 INITIALIZE MIRR1 SHOW MIRR1 Configuring a RAIDset 1.
FC Configuration Procedures 4. Assign the RAIDset a unit number to make it accessible by the hosts. See "Assigning Unit Numbers and Unit Qualifiers", page 175. For example: The commands to create RAID1, a RAIDset with three members (DISK10000, DISK20000, and DISK10100) and to initialize it with default values: ADD RAIDSET RAID1 DISK10000 DISK20000 DISK30000 INITIALIZE RAID1 SHOW RAID1 Configuring a Striped Mirrorset 1. Create, but do not initialize, at least two mirrorsets.
FC Configuration Procedures Configuring a Single-Disk Unit (JBOD) 1. Initialize the disk drive, specifying any desired switches: INITIALIZE DISK-NAME SWITCHES See "Specifying Initialization Switches", page 95, for a description of the initialization switches. 2. Verify the configuration by entering the following command: SHOW DISK-NAME 3. Assign the disk a unit number to make it accessible by the hosts. See "Assigning Unit Numbers and Unit Qualifiers", page 175. Configuring a Partition 1.
FC Configuration Procedures or SHOW DISK-NAME The partition number is displayed in the first column, followed by the size and starting block of each partition. 4. Assign the partition a unit number to make it accessible by the hosts. See "Assigning Unit Numbers and Unit Qualifiers", page 175. For example: The commands to create RAID1, a three-member RAIDset, then partition it into two storage units are shown below.
FC Configuration Procedures Assigning Unit Numbers and Unit Qualifiers Each storageset, partition, or single (JBOD) disk must be assigned a unit number for the host to access. As the units are added, their properties can be specified through the use of command qualifiers, which are discussed in detail under the ADD UNIT command in the HP StorageWorks HSG60 and HSG80 Array Controller and Array Controller Software Command Line Interface Reference Guide.
FC Configuration Procedures Preferring Units In multiple-bus failover mode, individual units can be preferred to a specific controller. For example, to prefer unit D102 to “this controller,” use the following command: SET D102 PREFERRED_PATH=THIS RESTART commands must be issued to both controllers for this command to take effect: RESTART OTHER_CONTROLLER RESTART THIS_CONTROLLER Note: The controllers need to restart together for the preferred settings to take effect.
FC Configuration Procedures Configuration Options There are multiple options that allow you to configure your system. Changing the CLI Prompt To change the CLI prompt, enter a 1- to 16- character string as the new prompt, according to the following syntax: SET THIS_CONTROLLER PROMPT = “NEW PROMPT” If you are configuring dual-redundant controllers, also change the CLI prompt on the “other controller.
FC Configuration Procedures Note: This procedure assumes that the disks that you are adding to the spareset have already been added to the controller's list of known devices. To add the disk drive to the controller's spareset list, use the following syntax: ADD SPARESET DISKNNNNN Repeat this step for each disk drive you want to add to the spareset: For example: The following example shows the syntax for adding DISK11300 and DISK21300 to the spareset.
FC Configuration Procedures To disable autospare, use the following command: SET FAILEDSET NOAUTOSPARE During initialization, AUTOSPARE checks to see if the new disk drive contains metadata. Metadata is information the controller writes on the disk drive when the disk drive is configured into a storageset. Therefore, the presence of metadata indicates that the disk drive belongs to, or has been used by, a storageset. If the disk drive contains metadata, initialization stops.
FC Configuration Procedures Displaying the Current Switches To display the current switches for a storageset or single-disk unit, enter a SHOW command, specifying the FULL switch: SHOW STORAGESET-NAME or SHOW DEVICE-NAME Note: FULL is not required when showing a particular device. It is used when showing all devices, for example, SHOW DEVICES FULL.
FC Configuration Procedures Verifying Storage Configuration from Host This section describes how to verify that LUNs (virtual disk units) are being correctly presented to HP-UX. After configuring units (virtual disks) through either the CLI restart the host. If you are adding units dynamically, then use ioscan and insf -e commands to verify that the device special files and logical unit numbers are created and correctly assigned to each storageset.

Backing Up, Cloning, and Moving Data 7 This chapter includes the following topics: ■ "Backing Up Subsystem Configurations", page 196 ■ "Creating Clones for Backup", page 197 ■ "Moving Storagesets", page 201 HSG80 ACS Solution Software V8.
Backing Up, Cloning, and Moving Data Backing Up Subsystem Configurations The controller stores information about the subsystem configuration in its nonvolatile memory. This information could be lost if the controller fails or when you replace a module in the subsystem. Use the following command to produce a display that shows if the save configuration feature is active and which devices are being used to store the configuration.
Backing Up, Cloning, and Moving Data Creating Clones for Backup Use the Clone utility to duplicate the data on any unpartitioned single-disk unit, stripeset, mirrorset, or striped mirrorset in preparation for backup. When the cloning operation is complete, you can back up the Clones rather than the storageset or single-disk unit, which can continue to service its I/O load. When you are cloning a mirrorset, Clone does not need to create a temporary mirrorset.
Backing Up, Cloning, and Moving Data To Clone a single-disk unit, stripeset, or mirrorset: 1. Establish a connection to the controller that accesses the unit you want to Clone. 2. Start Clone using the following command: RUN CLONE 3. When prompted, enter the unit number of the unit you want to Clone. 4. When prompted, enter a unit number for the Clone unit that Clone creates. 5.
Backing Up, Cloning, and Moving Data The following example shows the commands you would use to Clone storage unit D6. The Clone command terminates after it creates storage unit D33, a Clone or copy of D6. RUN CLONE CLONE LOCAL PROGRAM INVOKED UNITS AVAILABLE FOR CLONING: 98 ENTER UNIT TO CLONE? 98 CLONE WILL CREATE A NEW UNIT WHICH IS A COPY OF UNIT 98. ENTER THE UNIT NUMBER WHICH YOU WANT ASSIGNED TO THE NEW UNIT? 99 THE NEW UNIT MAY BE ADDED USING ONE OF THE FOLLOWING METHODS: 1.
Backing Up, Cloning, and Moving Data .

IT IS A CLONE OF D98. CLONE - NORMAL TERMINATION 200 HSG80 ACS Solution Software V8.
Backing Up, Cloning, and Moving Data Moving Storagesets You can move a storageset from one subsystem to another without destroying its data. You also can follow the steps in this section to move a storageset to a new location within the same subsystem. Caution: Move only normal storagesets. Do not move storagesets that are reconstructing or reduced, or data corruption results. See the release notes for the version of your controller software for information on which drives can be supported.
Backing Up, Cloning, and Moving Data 5. Delete each disk drive, one at a time, that the storageset contained. Use the following syntax: DELETE DISK-NAME DELETE DISK-NAME DELETE DISK-NAME 6. Remove the disk drives and move them to their new PTL locations. 7. Again add each disk drive to the controller's list of valid devices. Use the following syntax: ADD DISK DISK-NAME PTL-LOCATION ADD DISK DISK-NAME PTL-LOCATION ADD DISK DISK-NAME PTL-LOCATION 8.

Installing, Configuring, and Removing the Client B The following information is included in this appendix: ■ "Why Install the Client?", page 226 ■ "Before You Install the Client", page 227 ■ "Installing the Client", page 228 ■ "Installing the Integration Patch", page 229 ■ "Troubleshooting Client Installation", page 232 ■ "Adding Storage Subsystem and its Host to Navigation Tree", page 234 ■ "Removing Command Console Client", page 236 ■ "Where to Find Additional Information", page 238 HSG8
Installing, Configuring, and Removing the Client Why Install the Client? The Client monitors and manages a storage subsystem by performing the following tasks: 226 ■ Create mirrored device group (RAID 1) ■ Create striped device group (RAID 0) ■ Create striped mirrored device group (RAID 0+1) ■ Create striped parity device group (3/5) ■ Create an individual device (JBOD) ■ Monitor many subsystems at once ■ Set up pager notification HSG80 ACS Solution Software V8.
Installing, Configuring, and Removing the Client Before You Install the Client 1. Verify that you are logged into an account that is a member of the administrator group. 2. Check the software product description that came with the software for a list of supported hardware. 3. Verify that you have the SNMP service installed on the computer. SNMP must be installed on the computer for this software to work properly. The Client software uses SNMP to receive traps from the Agent.
Installing, Configuring, and Removing the Client Installing the Client The following restriction should be observed when installing SWCC on Windows NT 4.0 Workstations. If you select all of the applets during installation, the installation fails on the HSG60 applet and again on one of the HSG80 applets. The workaround is to install all of the applets you want except for the HSG60 applet and the HSG80 ACS 8.5 applet. You can then return to the setup program and install the one that you need. 1.
Installing, Configuring, and Removing the Client Installing the Integration Patch The integration patch determines which version of firmware the controller is using and launches the appropriate StorageWorks Command Console (SWCC) Storage Window within Insight Manager (CIM) V4.23. Should I Install the Integration Patch? Install this patch if your HSG80 controller uses ACS 8.6 or later. This patch enables you to use the controller’s SWCC Storage Window within CIM to monitor and manage the controller.
Installing, Configuring, and Removing the Client Caution: If you remove the integration patch, HSG80 Storage Window V2.1 no longer works and you need to reinstall HSG80 Storage Window V2.1. The integration patch uses some of the same files as the HSG80 Storage Window V2.1. Integrating Controller’s SWCC Storage Window with CIM You can open the controller’s Storage Window from within the Windows-based CIM V4.23 by doing the following: 1.
Installing, Configuring, and Removing the Client “Insight Manager Unable to Find Controller’s Storage Window” If you installed Insight Manager before SWCC, Insight Manager is unable to find the controller’s Storage Window. To find the controller’s Storage Window, perform the following procedure: 1. Double-click the Insight Agents icon (Start > Settings > Control Panel). A window is displayed showing you the active and inactive Agents under the Services tab. 2.
Installing, Configuring, and Removing the Client Troubleshooting Client Installation This section provides information on how to resolve some of the problems that may occur when installing the Client software: ■ ■ Invalid Network Port Assignments During Installation “There is no disk in the drive” Message Invalid Network Port Assignments During Installation SWCC Clients and Agents communicate by using sockets.
