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 De
finition 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® p
air volume.
• XP Business Copy Quick Restore operations affecting multiple CLPRs.
• XP Auto LUN manual migrations affecting multiple CLPRs.
• If you per
form 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 pe
rform 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 b
elong 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
• Portsbeing assigned to an SLPR should nothaveexistinghostgroupsand 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
