Disabling data encryption on a parity group that does not contain pool volumes

Use this procedure to disable encryption on a parity group that does not contain any pool volumes.

You can disable encryption on a parity group only when the parity group does not contain any volumes, or when all volumes in the parity group are blocked. If the parity group contains any unblocked volumes, you must block the volumes before encryption can be disabled.

Before you begin

  • You must have the Security Administrator (View & Modify) role to disable encryption.
  • If the target parity group contains volumes, you must have the Storage Administrator (Provisioning) role to format the volumes.

Procedure

  1. In the Explorer pane, expand Storage Systems, and select Parity Groups.

  2. On the Parity Groups tab, confirm that all volumes in the target parity group are blocked (Blocked is displayed in the LDEV Status column).

    If the LDEV status of the parity group is not Blocked, block the LDEVs. You will not be able to disable encryption if the parity group contains unblocked volumes.

  3. On the Parity Groups tab, select the target parity group, and then click Edit Encryption.

    CautionIf you do not select one or more specific parity groups, all parity groups are selected.

  4. In the Edit Encryption window, select the desired settings for each parity group:

    1. In the Available Parity Groups table, select the parity group.

    2. For Encryption, select Disable.

    3. For Format Type, select the desired format type.

      If the parity group contains a pool volume, select Normal Format. If you select Quick Format, an error will occur when you perform the task.

    4. Click Add.

      The parity group is added to the Selected Parity Groups list.

      If there are no volumes in the parity group, the format type in the Selected Parity Groups list is displayed as a hyphen (-).

    5. If you want to change the format type of a parity group in the Selected Parity Groups list, select the parity group, click Remove, and then add the parity group to the Selected Parity Groups list again with the desired format type.

  5. When you are finished adding parity groups to the Selected Parity Groups list, click Finish.

  6. In the Confirm window, confirm the settings, and enter your task name in Task Name.

    If you want the Task window to open after you click Apply, select Go to tasks window for status.

  7. Click Apply, and then click OK in the message that appears.
