Removing the SED

If you incorrectly remove a Self-Encrypting Drive (SED), it puts that drive into an unusable state. To avoid this situation, follow these instructions.

To remove a Self-Encrypting Drive (SED) from a Nutanix cluster:

WARNING:Do not remove any SEDs from your key management server before properly removing them from the Nutanix Cluster.
  1. Use the Prism Web Console to prepare to remove the drive for replacement.
  2. As part of the disk removal process, the data encryption key (DEK) for that SED automatically cycles on the drive controller. The previous DEK is lost and all new disk reads are indecipherable.
  3. After this process is completed, a yellow LED indicator blinks on the drive to be removed.
