Forcibly restoring encryption keys

If encryption keys cannot be used, including the keys backed up as the primary backup in storage system, restore the encryption keys backed up as the secondary backup. Backed up encryption keys for which key information is lost or deleted are restored in a batch. The following table lists the maximum number of backed up encryption keys.

NoteTo restore the encryption key, the volumes that belong to the parity group for which encryption is set must be blocked. In addition, after the key is restored, the volumes that belong to the parity group for which encryption is set must be restored.
CautionIf you restore an encryption key that is not the latest key, the drive, EDKA, or controller might be blocked, and the data might not be read.
