5-1 Managing a Storage Pool
Provisioning Manager manages volumes that exist in multiple storage subsystems as a single logical storage
area (a storage pool). Provisioning Manager enables you to do the following to manage storage pools.
• View a storage pool from the following perspectives:
• Storage subsystem for each model
• Storage subsystem for each RAID level
• Storage subsystem for each series
• Each storage subsystem
• View a list of volumes allocated to the host
• View a list of volumes not allocated to the host
• Allocate and release volumes in the storage pool
• Move volumes between storage pools
A storage pool is associated with a user group. User groups can have a hierarchical relationship with other
user groups. The users who belong to a user group can access the storage pools associated with lower-level
user groups. For example, suppose that the parent group P_Group has child groups C_Group01 and
C_Group02
, and the child user group C_Group01 has the grandchild group GC_Group. Figure 5-1 illustrates
these relationships.
