9.9 Volatile Key
Volatile key is supported only when maxCrypto is operating in Remote Key Management Mode and the logical device is encrypted. Data keys are stored in volatile memory instead of disk. This provides stronger data protection, but it can also cause the data to be inaccessible during power loss when the volatile key is not backed-up.
Once Volatile Key With Backup option is enabled, the data key will be backed up to remote key manager when enabling the volatile key. You have an option to restore the key from the remote key manager. If disabled, the data key will not be backed up to remote key manager.
Warning: Enabling volatile key on a logical device prevents the key from being stored in the disk. Under any condition where the controller is reset (such as from a power loss or server reboot), the key gets destroyed and the data in the logical device becomes inaccessible. There is no method available to recover the volatile key or access the data on the logical device.
