Modify host master key (HMK)
To modify the host master key, use the NetBackup Key Management Service (KMS) utility command (the nbkmsutil command) with the included arguments.
The HMK is used to encrypt the keystore. To modify the current HMK, the user should provide an optional seed or pass phrase. An ID (HMK ID) should also be provided that can remind them of the specified pass phrase. Both the pass phrase and HMK ID are read interactively.
