Issue

  • A SED requires an authentication key to unlock it and make the data on the drive accessible.
  • Unless the authentication key is the MSID (Manufacturer Secure ID), the authentication key is maintained by a key manager.
  • If a node with an SED (having a non-MSID authentication key) is unjoined from a cluster, the SED loses access to the authentication key.
  • Without the authentication key, the SED remains locked and the SED data will be unavailable.
