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.
