Dell OMSS Virtual disk degraded

Dell.WindowsServer.StorageManagement.Alert.2057 (Rule)

Knowledge Base article:

Summary

Virtual disk degraded

Causes

Cause 1: This alert message occurs 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.

Cause 2: A physical disk in the disk group has been removed.

Cause	Resolutions
arg1 has become degraded.	Configure a hot spare for the virtual disk if it is not already configured. Rebuild the virtual disk. If a physical disk was removed from the disk group, either replace the disk or restore the original disk.

Resolutions

Action 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 controller, rebuild the virtual disk by first configuring a hot spare for the disk, and then initiating a write operation to the disk. The write operation will initiate a rebuild of the disk.

Action 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 using Dell OpenManage Storage Management by locating the disk that has a red "X" for its status. Perform a rescan after replacing the disk.
