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 used on an FMC parity group if the parity group meets any of the following conditions:

• Encryption is enabled on the parity group.
• The LDEV carved from the parity group is 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 the LDEV that is carved from the parity group.

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