• When there is no Thin Provisioning License registered, the [Create/
Extend Thin Provisioning Pool] function cannot be executed.
• After creating the Thin Provisioning Pool, registered RAID Group
information (RAID levels and disk drive types) cannot be changed. To
change the RAID Group information, delete the target Thin Provisioning
Pool, and create it again.
• After creating the Thin Provisioning Pool, the Pool capacity can be
expanded in units of RAID Groups. New RAID Groups are added in the
Pool according to the existing RAID Group information (RAID levels and
disk drive types). When changing RAID Group information, create a new
Thin Provisioning Pool.

cannot be created.

number of RAID Groups) are insufficient

Provisioning Pools can be assigned to all the Resource Domains.
