Internal volume other than an LDEV in a parity group with accelerated compression enabled.

NoteIf you format DP-VOLs for which the capacity saving setting is disabled and Deduplication Data is Enabled, the capacity saving setting for the DP-VOLs might become Compression. If you format the deduplication system data volume for a pool that has DP-VOLs for which the capacity saving setting is disabled and Deduplication Data is Enabled, the capacity saving setting for the DP-VOLs might become Deduplication and compression. Therefore, verify the capacity saving setting of DP-VOLs after the format operation completes.
