Virtual disk degraded: Virtual Disk 1 (Virtual Disk 1) Controller 0 (PERC 5/i Integrated)
Logged on DELL servers. This indicates that a drive in the SCSI array failed and needs to be replaced as soon as possible if you do not have a hot-spare drive.
This event does not tell you which drive failed, but it states that a drive in a configured virtual (logical) disk is offline.
