1 XP Disk/Cache Partition for the XP10000/XP12000The HP StorageWorks XP Disk/Cache Partition feature prevents performance degradation and data loss that occur when connecting multiple hosts and sharing disk arrays among multiple departments and multiple companies.

XP Disk/Cache Partition provides a mechanism to safeguard disk array configurations by isolating operational areas. There is a possibility of changing or deleting a configuration created for a specific customer by mistake. The configuration should be protected from unrelated tasks, such as a path through which a host is connected and performing I/O, that could interrupt work in progress.

Use XP Disk/Cache Partition to partition a disk array into multiple virtual disk arrays. This helps protect data because the virtual disk array’s administrator cannot access the other virtual disk arrays for which the administrator is responsible.

XP Disk/Cache Partition featuresXP Disk/Cache Partition has two components:

• ”Cache logical partitions (CLPRs)” on page 9• ”Storage management logical partitions (SLPRs)” on page 10

Cache logical partitions (CLPRs)When one disk array is shared with multiple hosts, and one host reads or writes a large amount of data, the host’s read and write data occupies a large area in the disk array’s cache memory. In this situation, the I/O performance of other hosts decreases because the hosts must wait to write to cache memory. To prevent this situation, CLPR partitions the disk array’s cache memory. Partitioned cache memories are used as virtual cache memories, and each is allocated to each host. This approach minimizes the effects of one administrator’s operations on other administrators’ volumes.

10 XP Disk/Cache Partition for the XP10000/XP12000

Virtual cache memory that the cache logical partition function partitions is referred to as CLPR.

Figure 1 Example of a CLPR

Figure 1 shows how a corporation’s cache memory is partitioned to three virtual cache memories. Although the Branch A host is inputting and outputting a large amount of data, the Branch B and Branch C hosts are unaffected because each branch is allocated 40 GB CLPR.

NOTE: When adding cache memories to the local disk array, install them with Standard Cache Access Model or High Performance Cache Access Model mode. If the local disk array has additional printed circuit boards (PCBs), you must use High Performance Cache Access Model mode. Contact your HP account support representative for more information about additional cache memories.

Storage management logical partitions (SLPRs)A disk array can be shared with multiple organizations and multiple departments within an enterprise. Therefore, multiple administrators might manage a single disk array. This creates the potential for an administrator to destroy other organizations’ volumes, and it can complicate and increase the difficulty of managing the disk array.

Use XP Disk/Cache Partition to allocate all of one disk array’s resources (all ports and CLPRs) to virtual disk arrays called SLPRs. You can create up to 31 SLPRs in one disk array. Each virtual disk array can be accessed only by its administrator. This approach eliminates the risk of an administrator destroying other organizations’ volumes and of data leaks among organizations.

In a non-partitioned environment, a full array is considered one single partition SLPR0. After the disk array is partitioned, SLPR0 becomes the unpartitioned portion of the disk array. Similarly, CLPR0 contains all


parity groups (PGs) and cache in the non-partitioned environment. After the disk array is partitioned, CLPR0 contains the remaining PGs and cache that are not allocated to other CLPRs.

Figure 2 Example of an SLPR

Figure 2 shows an example of one disk array partitioned into two virtual disk arrays. Each virtual disk array is allocated to one enterprise. Enterprise A’s disk array administrator can manage enterprise A’s virtual disk array, but cannot manage enterprise B’s disk array. Similarly, enterprise B’s disk array administrator can manage enterprise B’s virtual disk array, but cannot manage enterprise A’s disk array.

Partition administration and administrator rightsThe following groups of users can access XP Disk/Cache Partition:

• Administrators who have modify access to the full disk array.• StorageAdmins who have modify access. This group consists of users who have full array access and

users who have partition-level access.• Users who have read-only access. This group consists of users who have full array access and users

who have partition-level access

default is 4 GB.• Cache LUN Size: Cache LUN capacity. Must be between 0 and 252 GB in 0.5 GB increments. The

default is 0 GB. If the total amount of defined cache LUN in the selected CLPR is larger than the setting for Cache LUN Size, an error occurs.

• Number of Cache LUN Areas: Number of cache LUN areas. Must be between 0 and 4,096. The default is 0. If the total amount of defined Cache Residency Area in the selected CLPR is more than the setting for Number of Cache LUN Areas, an error occurs.

• Partial Cache Residence Size: Partial Cache Residence (PCR) capacity. Must be between 0 and 252 GB in 0.5 GB increments. The default is 0 GB. If the total amount of defined Partial Cache Residence Size is more than the setting for Partial Cache Residence Size, an error occurs.

NOTE: You cannot change the capacity value of CLPR0 directly. If you change another CLPR’s capacity, the difference is reflected in CLPR0’s capacity.


NOTE: The maximum available cache capacity (capacity of mounted cache minus total amount of usage for other CLPRs) is displayed for each upper limit of Cache Size, Cache LUN Size, Number of Cache LUN Areas, and Partial Cache Residence Size.

The remaining capacity, which is calculated by subtracting Cache LUN Size and Partial Cache Residence Size from Cache Size, must be 4 GB or more in CLPR0.

NOTE: For more information about Cache LUN and Partial Cache Residence, see the HP StorageWorks Cache LUN XP user guide for the XP10000/XP12000.

• Apply: Applies settings.• Cancel: Cancels settings that were entered or selected, and restores settings to initial values.

Creating CLPRsIf you have not yet created a CLPR, the entire cache appears in CLPR0 in the Partition Definition pane. To partition the cache, create a CLPR. The created CLPR can be allocated to each SLPR, and CLPRs can be created in a selected SLPR. Only the Administrators can create CLPRs.

NOTE: When you create a CLPR, the default cache size is 4 GB. To create a CLPR, the desired cache size is allocated from CLPR0 (entire cache). The remaining cache size, which is calculated by subtracting Cache Residency Size and Partial Cache Residence Size from the Cache Size of CLPR0, must be 8 GB or more.

1. Select an SLPR, right-click, and select Create CLPR. The CLPR is added to the tree.2. Select a CLPR. Information about the selected CLPR is displayed in the Detail For CLPR section.3. Change CLPR settings as needed.4. Click Apply.5. To allocate parity groups to a CLPR, migrate the parity groups from another CLPR (see ”Migrating

parity groups across CLPRs” on page 15).

• SLPR Name: Up to 32 alphanumeric characters.• CU(* in use): CU number in the specified SLPR (00 - 3F). An asterisk (*) indicates the SSID is

registered to the CU. To delete a CU from the specified SLPR and return it to the Available CU list, select the CU, and click Delete.

• Available CU(* in use): All CU numbers that are not in the specified SLPR. To add a CU to the specified SLPR, select the CU, and click Add. An asterisk (*) indicates the SSID is registered to the CU. You can select up to 64 CUs into which the SSIDs are registered or not.• SLPR: SLPR to the CU belongs to.• SSID(SLPR): SSID if the SSID is registered into a CU. The SLPR the SSID belongs to appears

between parentheses on the right of the SSID.


NOTE: If users in the StorageAdmins group who have partition-level access want to use the Customized Volume function, first specify the CU for each SLPR to prevent overlapping the newly allocated CU numbers and the existing CU numbers in other SLPRs. If CU numbers are not specified first, users in the StorageAdmins group who have partition-level access cannot use the Customized Volume function.

• SSID(* in use): SSID in the selected SLPR (0004 to FFFE). An asterisk (*) indicates the SSID is registered to the CU. SSIDs registered to the CU are displayed for SLPR0. If a customized volume (CV) is set using the Customized Volume function, and the CU number and SSID are registered to different SLPRs, a dash (-) appears to the right of the SSID. To delete an SSID from the SSID(* in use) box, select the SSID, and click Delete.

• From: Starting number of the SSID added to the specified SLPR (0004 to FFFE). You can enter an SSID that is in SLPR0.

• To: Last number of the SSID added to the specified SLPR (0004 to FFFE). There can be up to 256 SSIDs in SLPR0. If you add multiple SSIDs to a specified SLPR, the To number must be smaller than the From number.

NOTE: If users in the StorageAdmins group who have partition-level access use the Customized Volume function, first specify the SSID number for the SLPR to prevent overlapping newly allocated SSID numbers and existing SSID numbers in another SLPR.

• Apply: Applies settings.• Cancel: Cancels settings entered or selected, and restores settings to initial values.

Administering SLPRsOnly storage administrators can make settings for SLPR0. A storage partition administrator only has authority within the assigned storage logical partition. The storage administrator can also assign write permission for one or more of the following functions:

• Volume Management• LUN Security XP Extension• LUN Manager• Cache LUN XP• Auto LUN XP

The following is the general procedure required for preparing and administering the disk array with SLPRs. Only Administrators can perform this procedure.

1. Create an SLPR (see ”Creating SLPRs” on page 18).2. On the License Key Partition Definition pane, allocate licenses for software products to the SLPR (see the

HP StorageWorks Command View XP user guide for XP Disk Arrays or the HP StorageWorks XP Remote Web Console user guide for the specific disk array).

NOTE: If software product licenses have not been allocated to an SLPR, the user assigned to the SLPR cannot use the software products. For Auto LUN XP, if the licensed capacity for the entire storage is sufficient, the Administrator can use Auto LUN XP to monitor the entire storage, even if Auto LUN XP’s license has not been allocated to the SLPR.

3. For instructions on adding users, see the HP StorageWorks Command View XP user guide for XP Disk Arrays or the HP StorageWorks XP Remote Web Console user guide for the specific disk array.

4. To delete an SLPR, delete all users and set the license capacity to 0 GB, or click Disable for all software products assigned to the SLPR on the License Key Partition Definition pane. See ”Deleting SLPRs” on page 18.


NOTE: You can assign a user to an SLPR that has not yet been created. However, if the SLPR does not exist, an error occurs when that user attempts to launch Command View AE or XP Remote Web Console.

Creating SLPRsIf you have not yet created an SLPR in the disk array, all of the disk array’s resources are in SLPR0. To divide the resources, create a new SLPR. Only Administrators can create SLPRs.

1. Right-click Subsystem, and select Create SLPR.2. Select an SLPR.3. Change SLPR settings as needed.4. Click Apply.5. Allocate resources (CLPRs and ports) to an SLPR. To do so, create a CLPR in an SLPR (see ”Creating

CLPRs” on page 15) or migrate a port from another SLPR (see ”Migrating SLPR resources” on page 18).

NOTE: To change an existing SLPR’s settings, repeat step 1 through step 4.

Deleting SLPRs

NOTE: You cannot delete SLPR0.

When you delete an SLPR, partitioned resources are automatically returned to SLPR0. Only Administrators can delete SLPRs.

1. Right-click the SLPR, and select Delete SLPR.2. Click Apply.

Migrating SLPR resourcesYou can migrate CLPRs and ports that are managed in an SLPR to another SLPR.

• You can migrate only Target ports to another SLPR. You cannot migrate Initiator ports, RCU Target ports, and External ports.

• A NAS port belonging to the same channel adapter must belong to the same SLPR.1. Select an SLPR from the tree. The SLPR resource list appears.2. Select the CLPR or port you want to migrate, right-click, and select Cut. You can select multiple CLPRs or

ports.

NOTE: To migrate NAS ports, select all ports in the same CHN (channel adapter for the NAS) and the CLPRs containing LUN0000 and LUN0001 that belong to the NAS-Sys host group, and migrate them at the same time.

3. Select the SLPR you want to migrate the CLPR or port to, right-click, and select Paste CLPRs, Ports. If you migrated CLPRs, they are added to the tree and SLPR resource list. If you migrated ports, they are added only to the SLPR resource list.

NOTE: The LUN0000 and LUN0001 belonging to the NAS-Sys host group must belong to the same SLPR as the NAS port. LUNs from LUN0005 to LUN000A in the NAS system LU must belong to SLPR0.

4. Click Apply to apply settings.


Displaying error messagesIf settings contain a discrepancy, an error message appears when you click Apply. To display the error message again, right-click the SLPR, and select Error Detail.

Notes, restrictions, and requirementsThis section provides additional information about using SLPRs and CLPRs.

CLPRs• When you create a partition, the partition’s license keys are disabled by default. Use the License Key

Partition Definition tab on the Install pane to enable license keys for the new partition. Basic license keys include XP Web Console and Java® API. Both are required to enable the Web GUI for new partitions.

• Adding or changing a CLPR definition can take several hours. To minimize the amount of time required when moving cache from one CLPR to another, create partitions when the disk array workload is light.

• The following operations are not recommended with CLPRs:• Creating a LUSE volume that extends over multiple CLPRs. If performed, volumes belonging to the

CLPRs to which the LUSE is set cannot be used as a Continuous Copy XP or TrueCopy for z/OS® pair volume.

• Business Copy XP Quick Restore operation that affects multiple CLPRs.• Manual Migration of Volume Migration that affects multiple CLPRs.

• If Continuous Access XP Asynchronous or TrueCopy for z/OS Asynchronous operations are performed, and volumes that are extended over multiple CLPRs are allocated to the same consistency group, you cannot create a pair.

• If Continuous Access XP Asynchronous or TrueCopy for z/OS Asynchronous operations are performed, only Continuous Access XP Asynchronous or TrueCopy for z/OS Asynchronous pairs belonging to the same CLPR can be allocated to one consistency group. Parity groups allocated to the CLPR that these Continuous Access XP Asynchronous or TrueCopy for z/OS Asynchronous pairs belong to cannot migrate to another CLPR.

SLPRs• Ports being assigned to an SLPR should not have existing host groups and LUNs assigned to them.

Assign LUNs and define host groups after the partition is created.• Assign LUNs for an SLPR from array groups that are assigned to control units (CUs) that have been

assigned to that SLPR. The StorageAdmin for a partition can only allocate from array groups belonging to the StorageAdmin’s assigned partition.

• HP does not recommend making settings on multiple SLPRs in a single operations because it results in more complex and difficult SLPR administration.

• If an administrator forces the following functions for multiple SLPRs and contradictions occur as a result, the StorageAdmin user‘s ability to use the SLPR is affected:• Manual migration of Volume Migration• Business Copy XP Quick Restore• LU path settings• High-speed mode settings • Creating a LUSE volume

• Mainframe volumes must be allocated to SLPR0.• Target ports must be allocated to SLPRs other than SLPR0; allocation cannot be done to SLPR0.• Before a customized volume (CV) is created, the StorageAdmins user must allocate CU numbers to the

SLPR. Allocated CU numbers are required only for defining the CU number to be allocated to the LDEV when the StorageAdmin user creates a CV.
