Initializing all deduplication-enabled DP-VOLs in a pool

You can restore DP-VOLs whose capacity saving status is Failed by initializing all DP-VOLs of which deduplication is enabled in a pool.

When you initialize all DP-VOLs of which deduplication is enabled in a pool, all deduplication system data volumes are also initialized.

NoteIf you initialize duplicated data for the 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 formatting operation completes.

Before you begin

  • Because this procedure deletes all user data in the deduplication-enabled DP-VOLs, back up all affected DP-VOLs in advance.
  • The Storage Administrator (Provisioning) role is required to perform this task.

Procedure

  1. Click Storage Systems, expand the Storage Systems tree, then select the pool.

  2. Click the Virtual Volumes tab.

  3. Block DP-VOLs that are associated with the pool in the following order:

    1. DP-VOLs whose Deduplication Data is Enabled.

    2. Deduplication System Data Volume.

  4. Click More Actions, and select Initialize Duplicated Data.

  5. Click Apply.

    If the Go to tasks window for status check box is selected, the Tasks window displays.

  6. Because the status of DP-VOLs that are initialized in the duplicated data is Blocked, format DP-VOLs in the following order:

    1. Deduplication System Data Volume (data store).

    2. DP-VOLs whose Deduplication Data is Enabled.
