Verifying a Failed
Disk Drive
If either disk fails while in a fully mirrored state, the system continues to
operate. The disk LED states described in Tab le 59 indicate which drive
has failed. In addition, the Disk Status window in NBX NetSet shows the
status of your disk drives.
To verify the status of a disk drive, select Reports > System Data > Disk
Status. See the Help for information on verifying disk status.
