Checking whether accelerated compression can be enabled

Before enabling accelerated compression on a parity group, check whether it can be used with the parity group. Accelerated compression cannot be enabled on a parity group if the parity group meets any of the following conditions:

• The LDEVs carved from the parity group are not used as a pool volume.
• The LDEVs carved from the parity group are used as pool volumes in multiple pools.
• The full allocation function is enabled for all or any single DP-VOL associated with the pool containing LDEVs carved from the parity group.

If a DP-VOL that is associated with a pool containing an LDEV created from an FMD parity group is used as a journal volume of a Universal Replicator pair, we do not recommend using accelerated compression on this parity group.

If BED/controller-based encryption is enabled on the parity group, we do not recommend using accelerated compression on this parity group.
