| Description | Virtual disk degraded. |
| More Information | Cause 1: This event is logged when a physical disk included in a redundant virtual disk fails. Because the virtual disk is redundant (uses mirrored or parity information) and only one physical disk has failed, the virtual disk can be rebuilt. Resolution 1: Configure a hot spare for the virtual disk if one is not already configured. Rebuild the virtual disk. When using an Expandable RAID Controller (PERC) PERC 3/SC, 3/DCL, 3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di,CERC ATA100/4ch, PERC 5/E, PERC 5/i or a Serial Attache SCSI (SAS) 5/iR. Cause 2: Cause 2: A physical disk in the disk group has been removed. Resolution 2: If a physical disk was removed from the disk group, either replace the disk or restore the original disk. You can identify which disk has been removed by locating the disk that has a red “X” for its status. Perform a rescan after replacing the disk. |
