Notes: Set to `Disable` if the pool is created by Command Control Interface. Command Control Interface cannot be used to create Dynamic Tiering pools initially. You can use the raidcom modify pool command to modify Dynamic Provisioning pools for use as Dynamic Tiering or active flash pools. You can rename a pool when adding pool-VOLs to it. Recommendation is to specify 0% for SSD and 8% for other drives.
