Notes on data placement profiles for Smart volumes
When using data placement profiles for Smart volumes, it is useful to understand the following:
•
Data placement profiles are applied only to pages placed in Tier 1 of Smart pools.
•
For pages to which both a data placement profile and tiering policy are set, the settings of the
profile are prioritized.
•
After a data placement profile has been applied and monitoring and data relocation of Smart
pools has been performed, a data placement is restored. Therefore, users need to determine the
timing at which to apply a profile by taking into account the period during which the monitoring
and data relocation are performed.
•
When performing a create, update, apply, or release of a data placement profile, or when
searching for or repairing an inconsistency in a data placement profile, users cannot perform
other operations for the target storage system.
