Replacing a self-encrypting disk (SED) is similar to replacing a regular disk, except that there are some extra steps you must take to reenable Storage Encryption after you replace the disk.
Before you begin
You should know the key used by the SEDs on your storage system so that you can configure the replacement SED to use the same key.
- Ensure that reconstruction has started by entering the following command:aggr status -r
The status of the disk should display as "Reconstructing".
- Remove the failed disk and replace it with a new SED, following the instructions in the hardware guide for your disk
- Assign ownership of the newly replaced SED by entering the following command: disk assign disk_name
- Confirm that the new disk has been properly assigned by entering the following command: disk encrypt show
You should see the newly added disk in the output.
- Encrypt the disk by entering the following command:disk encrypt rekey key_id disk_name
- Finalize the replacement process by entering the following command: disk encrypt lock disk_name
The newly replaced SED is ready for use, and Storage Encryption is enabled and working on this system.
