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

You can enable encryption on a parity group only under the following conditions:

The parity group must not contain any volumes, or all volumes in the parity group must be blocked. If the parity group contains any unblocked volumes, you must block the volumes before encryption can be enabled.
Accelerated compression must not be enabled on the parity group. If accelerated compression is enabled on the parity group, you must disable accelerated compression before encryption can be enabled. For details about disabling accelerated compression, see the Provisioning Guide.

The encryption environmental settings must already be configured.
You must have the following user roles:
- Security Administrator (View & Modify) role to enable encryption
- Storage Administrator (Provisioning) role to block or format volumes during the enable encryption operation

CAUTION:

Enabling encryption on a parity group is a destructive operation. Verify the correct parity group ID before performing this operation. You are responsible for backing up the data in the target parity group, if necessary, before performing this operation.

In the Explorer pane, expand the Storage Systems tree, and then select Parity Groups.
On the Parity Groups tab, select the target parity group, and then click More Actions > Edit Encryption.

CAUTION:
If you do not select one or more specific parity groups, all parity groups are selected.
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 Enable.
  If the parity group contains unblocked volumes, or if accelerated compression is enabled for the parity group, an error will occur when you perform this task.
3. For Format Type, select the desired format type.
  If the parity group does not contain pool volumes, you can select Normal Format or Quick Format. If you select No Format, the LDEVs in the encrypted parity group will be blocked.
  If the parity group contains pool volumes, select Normal Format. If you select Quick Format, an error will occur when you perform this task.
  
  Note: (VSP E series) If an error occurs when you perform these tasks, recover from the error by formatting the parity group.
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.
When you are finished adding parity groups to the Selected Parity Groups list, click Finish.
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.
Click Apply, and then click OK in the message that appears.
