Maintenance mode enables you to perform the following operations to troubleshoot disk problems:
Note: For information about Maintenance mode, see "Booting from system boot diskette."
The disk_list command displays detailed device information for each disk on the system, such as drive type, and firmware revision level.
The disk_check command checks access to a particular disk, issuing read requests to the disk. The disk is active for approximately 15 seconds. During this time, you can watch the disk's activity LED to verify that the disk is accessed.
The disk_erase_label command erases a disk label on the specified disk drive.
Caution: Use the disk_erase_label command carefully because after a disk label is erased, RAID treats the disk as uninitialized and no longer recognizes it as a member of a RAID array.
Typically, use this command to remove an old RAID label on a previously used disk that you are adding to an existing RAID group. For example, use this command to erase the disk label when you move a disk from one filer to another.
