When configuring an on-premises StorageZone you are required to choose a passphrase, this is regardless of whether you choose to use encryption.
A phrase used to protect your file encryption key. Be sure to archive the passphrase and encryption key in a secure location.
You must use the same passphrase for each StorageZones Controller in a zone. The passphrase is not the same as your account password and cannot be recovered if lost. If you lose the passphrase, you cannot reinstall StorageZones, join additional StorageZones Controllers to the StorageZone, or recover the StorageZone if the server fails.
Note: The encryption key appears in the root of the shared storage path. Losing the encryption key file, SCKeys.txt, immediately breaks access to all StorageZone files. Be sure to back up the encryption key file as part of your normal datacenter procedures.
It is extremely important to not lose your passphrase as you will not be able to manage your StorageZone and will need to migrate data to a new StorageZone (Cloud or another on-premises StorageZone). You also won’t be able to backup your StorageZone configuration without the passphrase.
In the event you can’t remember your passphrase I would suggest you try to guess the passphrase.
Log in to your StorageZone Controller
Scroll to the bottom of the page and select Modify
Click the checkbox for Change Passphrase
Type the Old Passphrase and the New Passphrase and select Save.
If the Old Passphrase entered is not the passphrase you used you will receive Error changing passphrase: Old Passphrase does not match
When you have successfully guessed it you will receive a message StorageZone has been configured successfully!!
