2 cryptoCfg If there are CryptoTarget container/LUN configurations on the node and the encryption engines of this node are part of any HA Cluster configuration, this command prompts you to either continue leaving the encryption group while retaining the configuration, or to abort the leave operation. It is recommended that you remove the EEs from the HA cluster and delete any CryptoTarget container and Crypto LUN configurations from this node prior to initiating a leave operation. --genmasterkey Generates a master key. A master key is needed when an opaque key vault such as DPM is used. The master key must be exported (backed up) before it may be used. This command is valid only on the group leader. Only one master key per key vault is needed for the entire encryption group. When a master key is generated and a master key exists, the current master key becomes the alternate master Key and the newly generated master key becomes the current master key. --exportmasterkey Exports the current master key encrypted in a key generated from a specified pass phrase. By default this command backs up the key to the attached key vaults, or optionally to a predetermined file on the switch. This command is valid only on the group leader. This command prompts for a pass phrase. passphrase Specifies the pass phrase for the master key encryption. A pass phrase must be between 8 and 40 characters in length and can contain any character combination. Make a note of the pass phrase, because the same pass phrase is required to restore the master key from backup. This operand is required. -file Stores the encrypted master key in a predetermined file on the switch. This operand is optional. If the -file operand is not specified, the encrypted master key is stored in the attached key vaults, using a unique associate Key ID for tracking the export. Upon execution, this command displays both the associated Key ID and the master key ID. You can export the master key to the key vault more than once. Each time you export the same master key, the associate key ID is incremented, and both the master key ID and the associate key are displayed. Make a note of the key ID, because you will need same key ID is to restore the master key from backup. --recovermasterkey Restores the master key from backup. This command is valid only on the group leader. This command prompts for a pass phrase: passphrase Specifies the pass phrase for recovering the master key. The pass phrase must be the same that was used to back up the master key with the --exportmasterkey command. currentMK | alternateMK Specifies whether the master key should be restored to the current position or the alternate position. This command replaces the specified existing master key and should be exercised with caution. A master key is typically restored to the alternate position to enable decryption of older data encryption keys (DEKs) that were encrypted in that master key. -keyID keyID Specifies the associative master key ID. This option restores the master key from the key vault. The associative master key ID was returned when it was backed up to the key vault with the --exportmasterkey command. The -keyID and the -srcfile options are mutually exclusive. 188 Fabric OS Command Reference 53-1002746-01
