Prerequisites for allocating volumes from a tier
Before you allocate volumes from a tier, verify that:
• The hosts and storage systems are registered in P9000 Command View AE Software.
Verify that P9000 Command View AE Software detects the host and storage arrays by confirming
that the HP StorageWorks XP disk array is registered in P9000 Command View AE Software.
• An HP StorageWorks P9000 Tiered Storage Manager software license is enabled.
In addition, determine the requirements for the volumes and ports to be used according to the
environment and operational policies, including:
• The target host name
• The number and size of volumes required
• The storage systems to use
