Displaying error messages
If 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 requirements
This 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.
