6 Notes, restrictions, and

requirements

This chapter provides additional information about using SLPRs and CLPRs.

CLPRs

When creating a partition, the partition's license keys are disabled by default. Use the License Key

Partition Definition 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 array's

workload is light.

HP does not recommended the following operations with CLPRs:
• Creating a LUSE volume extending over multiple CLPRs. If performed, you cannot use volumes

belonging to the CLPRs to which the LUSE is set as a XP Continuous Access or TrueCopy

for z/OS® pair volume.

• XP Business Copy Quick Restore operations affecting multiple CLPRs.
• XP Auto LUN manual migrations affecting multiple CLPRs.

If you perform XP Continuous Access Asynchronous or TrueCopy for z/OS Asynchronous

operations, and allocate volumes that extend over multiple CLPRs to the same consistency group,

you cannot create a pair.

If you perform XP Continuous Access Asynchronous or TrueCopy for z/OS Asynchronous

operations, you can allocate only XP Continuous Access Asynchronous or TrueCopy for z/OS

Asynchronous pairs belonging to the same CLPR to one consistency group. Parity groups allocated

to the CLPR that these XP Continuous Access Asynchronous or TrueCopy for z/OS Asynchronous

pairs belong to cannot migrate to another CLPR.

The following CU groups are for mainframe volumes: CU40-7F, CU80-BF, and CUC0-FE.

Therefore, you cannot use these CU groups for some program products. For more information

about whether or not you can use all CU groups, see the user guide for each program product.

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:
• XP Auto LUN manual migration
• XP Business Copy Quick Restore
• LU path settings
• High Speed mode settings
• Creating

a

LUSE

volume
