"Does 'Redundant Virtual Disk" simply mean a virtual disk using a RAID configuration that has parity?" RAID 0 is NOT redundant; all other levels (1/5/6/10/50/60) are redundant.  Not all RAID configurations use parity.  RAID 1/10 do not use parity - they use mirroring.
Hi, I'm working on replacing a failing drive in an MD1000 RAID connected via PERC 6/E. I'm unsure about some terminology in the Server Administrator Storage Management User’s Guide. It refers often to a 'Redundant Virtual Disk', e.g. "Replacing a Failed Disk You may need to replace a failed disk in the following situations:  Replacing a Failed Disk that is Part of a Redundant Virtual Disk  Replacing a Failed Physical Disk that is Part of a Non-Redundant Virtual Disk "  Does 'Redundant Virtual Disk" simply mean a virtual disk using a RAID configuration that has parity? My configuration is RAID-50. If so, then this is a redundant virtual disk, right? So I can follow instructions meant for a redundant virtual disk? Thanks, Michael  
Is my RAID Virtual Disk Redundant?
