HP XP RAID Manager Software - Manual (Page 115)

Note *1: A multi tiered pool cannot be created initially using raid manager. You must first create
the pool using a single tier type, then enable smart and add the additional tier pool volumes.
Note *2: When the multiple tiering pool is enabled, the tiering control is set to "Manual"
automatically. To change the setting to "Auto", it is required to execute from Remote Web Console.
CAUTION: The operations are explained here are executable by the storage administrator only.
NOTE: Before creating a pool, it is required to create a virtual volume management area on the
cache memory. The virtual volume management area is created automatically when cache memory
is added. For the information about adding cache memory, please contact HP Technical Support.
