Possible Interacting and Conflicting Functions

It is possible for actions taken by a storage administrator to interact and conflict with actions taken by a partition storage administrator.

WARNING: If you are using HP StorageWorks XP RAID Manager, you must use command device security for the affected logical volumes, to prevent RAID Manager commands from having effects across SLPR boundaries. For more information on RAID Manager, see the HP StorageWorks XP RAID Manager User's Guide. For more information on securing command devices, see the HP StorageWorks XP24000/XP20000 LUN Manager User's Guide.

Before a storage administrator or storage partition administrator can create a customized volume (CV) using the Virtual LVI/LUN (VLL) function, the storage administrator must allocate the CU numbers to the SLPR. This is necessary so that the storage partition administrator can allocate LDEVs to those CU numbers when creating a customized volume. For more information on the VLL function, see the HP StorageWorks XP24000/XP20000 Virtual LVI/LUN (VLL) and Volume Shredder User's Guide.

WARNING: Making settings across SLPR boundaries is strongly discouraged, because you could cause unintended and serious consequences, including having a storage partition administrator be unable to perform one or more functions. If you attempt to make settings across more than one SLPR, a warning message is displayed. If you do make settings across SLPR boundaries, be extremely careful to avoid conflicts in LDKC, CU, and volume numbers across the various storage logical partitions.

For example, if a storage administrator performs any of the following types of actions across SLPR boundaries, this could cause serious problems for the storage partition administrators:

•Manual migration with volume migration. For more information, contact HP technical support. See “Calling HP Technical Support” on page 36.

•XP Business Copy Quick Restore (see the HP StorageWorks XP24000/XP20000 Business Copy Software User's Guide and the Hitachi ShadowImage™ for Mainframe User's Guide: HP XP24000 Disk Array, HP XP20000 Disk Array)
