UNUSABLE
A disk can change to an UNUSABLE state if the OS fails to initialize the disk on startup or when the disk is inserted into the Slicestor® device.
If a disk is in the UNUSABLE state, you can issue a password-protected Reset operation through the Manager Web Interface that starts a disk reformat. The functionality is equivalent to the nut storage reset command.
A Reset action button is available for UNUSABLE disks in the physical disk layout. This action reformats the disk. The Operator role cannot perform this action. A password is needed to proceed with the reset operation.
In an UNUSABLE state, any slices on the disk are inaccessible. When a disk changes from a DIAGNOSTIC state, the process of rebuilding missing slices is in progress on other disks.
