HP P9000 Provisioning for Open and Mainframe Systems User Guide

• Before creating a pool, you need a THP V-VOL management area in shared memory. When
shared memory is added, the THP V-VOL management area is automatically created. For
adding shared memory, contact your HP representative.
• In RAID Manager, when creating a pool, you cannot enable Multi-Tier Pool and cannot register
multiple media as pool-VOLs. Before making tiers, enable Multi-Tier Pool.
• Enabling Multi-Tier Pool from RAID Manager automatically sets Tier Management to Manual.
To change Tier Management to Auto, you must do this in Remote Web Console.
• If you delete a pool, its pool-VOLs (LDEVs) will be blocked. If they are blocked, format them
before using them.
