Verifying a Failed
Disk Drive
Table 54 Disk LED States (continued)
Explanation
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.
LED 2 and LED 3 flash alternately: the two disks
are resynchronizing
Synchronized
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.
