If you do not want to enter an encryption passphrase after every Avaya Aura® Device Services reboot and you do not have a remote key server, you can enable the local key store. However, the local key store is less secure than a remote key store or entering a passphrase after every reboot.

You can enable the local key store even if a remote key server is enabled. When both the local key store and the remote key server are enabled at the same time, Avaya Aura® Device Services uses the local key store to decrypt the encrypted disks at boot time.
