Formatting a specific LDEV

Use this procedure to perform Normal formatting on a volume.

Note
  • Formatting DP-VOLs with deduplication and compression enabled might take a while to complete. Also, the pool usage might increase by the format processing. Once the format processing starts, it cannot be stopped.

    If you want to format all DP-VOLs in a pool that have the capacity saving setting enabled, first block and then format the deduplication system data volume, and then format the DP-VOLs. Blocking and formatting the deduplication system data volume first can reduce the DP-VOL format processing time and prevent the increase in pool usage.

  • If you format DP-VOLs for which the capacity saving setting is disabled and the capacity saving status is other than Disabled, 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 the capacity saving status is other than Disabled, 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.
