The pool for Snapshot cannot be the same pool used for Thin Provisioning or Thin Provisioning
Z.
•
Up to 128 pools in total can be used for Thin Provisioning (including Smart Tiers), Thin
Provisioning Z, and Snapshot.

A pool-VOL cannot be shared among Thin Provisioning (including Smart Tiers), Thin Provisioning

Cache Partition CLPR setting
THP V-VOLs and the associated pool volumes should be assigned to the same CLPR.
•
For a Thin Provisioning or Smart Tiers pool, different CLPRs can be assigned to THP V-VOLs
in the same pool. In this case, the CLPR assigned to the pool volumes is ignored.
•
For a Snapshot pool, the same CLPR must be assigned for all the pool-VOLs in a pool.
