Formatting a specific LDEV

Use this procedure to perform Normal or Quick 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.

    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 in a pool for which Deduplication Data is Enabled, the capacity saving setting for the DP-VOLs might become Compression. Therefore, verify the capacity saving setting of the DP-VOLs after the format operation completes.
  • 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 the DP-VOLs after the format operation completes.
  • If Normal formatting is performed on the same storage system by multiple applications, the operation requested first is performed, and the operations requested later fail. For example, if Normal LDEV formatting is being performed by a maintenance PC and a Normal LDEV format is requested by the SVP, the LDEV format requested by the SVP fails.

Before you begin

  • The Storage Administrator (Provisioning) role is required to perform this task.
  • The status of the LDEV to be formatted must be Blocked. For information about blocking internal volumes, see Blocking LDEVs. For information about blocking external volumes, see the Universal Volume Manager User Guide.

Procedure

  1. Click Storage Systems, and then expand the Storage Systems tree.

  2. Click Logical Devices.

  3. In the Logical Devices window, select the LDEV ID of the LDEV you want to format.

    NoteWhen you format a deduplication system data volume, you must select only the (one) deduplication system data volume. Do not select any other volumes.

  4. Click More Actions, and select Format LDEVs.

  5. In the Format LDEVs window, select the desired format type (Normal or Quick), and then click Finish.

    You can select Quick only when the Provisioning Type of the selected LDEV is Basic and the parity group to which it belongs does not have accelerated compression enabled.

  6. Verify the settings in the Confirm window, enter a unique Task Name or accept the default, and click Apply.

    If Go to tasks window for status is checked, the Tasks window opens.
