Is my RAID Virtual Disk Redundant?
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

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.

Yes thanks, that makes sense. Redundancy through either parity or mirroring.
