Modifying (deleting) keys

You can modify the number of keys that a DS5000 storage server uses by deleting one or more keys. Before you begin, determine the changed information, such as the number of keys that you want to delete.

About this task

Delete keys only when the data protected by those keys is no longer needed. Deleting keys is like erasing the data. After keys are deleted, data that is protected by those keys is not retrievable.

You can use the Modify Keys dialog or the Delete Key REST Service to delete keys. Your role must have permissions to the modify action and to the appropriate device group.

Procedure

Go to the appropriate page or directory.
- Graphical user interface:
  1. Log on to the graphical user interface.
  2. In the Key and Device Management section on Welcome page, select DS5000.
  3. Click Go to > Manage keys and devices.
  4. Alternatively, right-click DS5000 and select Manage keys and devices.
- REST interface:
  - Open a REST client.
Modify the key information.
- Graphical user interface:
  On the management page for DS5000, select a device in the Device Serial Number column. Then, click Modify > Keys. Alternatively, right-click a device and then select Modify Keys.
  
  Then, on the Modify Keys dialog, select a key and click Delete. Read the confirmation message. Then, click OK.
- REST interface:
  Use the Delete Key REST Service to delete a key. For example, you can send the following HTTP request:
```
DELETE https://localhost:port/SKLM/rest/v1/keys/aaa000000000000000000
Content-Type: application/json
Accept : application/json
Authorization: SKLMAuth authId=139aeh34567m
```

What to do next

Next, you might associate the device with a machine.
