Disk Mirroring 345
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 Table 54
indicate which drive
has failed. In addition, the Disk Status window (Figure 141
) in the NBX
NetSet utility shows the status of your disk drives.
Figure 141 Disk Status Window
To verify the status of a disk drive, select Reports > System Data > Disk
Status. See the Help for information on verifying disk status.
Synchronizing — disk 1 is valid, disk 0 is
becoming a fully mirrored disk. LED 2 flash rate
indicates progress.
If LED 2 stops normal flashing and intermittently
flashes twice, the mirroring process has failed.
N/A Flashing On On
LED 2 and LED 3 flash alternately: the two disks
are resynchronizing
