Troubleshooting

To get help with your Dell Shared PowerEdge RAID Controller Shared (PERC) 8, you can contact your Dell Technical

Service representative or see dell.com/support.

In the event of some failure conditions encountered at boot, Shared PERC 8 boots up with restricted capability in safe

mode without user intervention. In such a condition Shared PERC 8 reports all configured disk drives as Foreign to the

management application. The Dell Chassis Management Controller (CMC) displays events generated by the controller

indicating the reason for booting into safe mode. The following table details the conditions and the corresponding event

notifications that are reported to the CMC.

Table 3. Conditions and the Corresponding Event Notifications Reported to the CMC

A redundant virtual disk is in a degraded state when one or more physical disks have failed or are inaccessible. For

example, if a RAID 1 virtual disk consists of two physical disks and one of them fails or become inaccessible, the virtual

disk become degraded.

To recover a virtual disk from a degraded state, you must replace the failed physical disk and rebuild it. After the

rebuilding process is complete, the virtual disk state changes from degraded to optimal.
