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 39
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:
1 Log on to the NBX NetSet utility using the administrator login ID and
password.
2 Click Reports > System Data > Disk Status. See the Help for information
on verifying disk status.
Flash codes indicate disk problem:
■
2 flashes: No valid disk (system is halted)
■
3 flashes: Two valid disks, but they are not
paired (system is halted)
■
4 flashes: Configuration problem (system is
halted)
■
5 flashes: Two disks present, but no
mirroring license
