Intel ESRT RAID 5, Medium Errors, Backups on SBS2008
Posted on 2013-05-12
My SBS2008, Intel S5500HCV with Four WD1003FBYX Drives in on-board RAID 5, failed this morning. It was in a circular BSOD reboot pattern failing on the megasrx.sys file. I knew this was a RAID driver so ran a consistency check on VD0 (OS volume) and the system now boots and is running. The RAID Web Console is showing multiple Medium errors on three of the four drives now. A few questions...
Does the fact that multiple drives showing multiple medium errors mean that the on-board RAID controller has issues, one drive has issues that is multiplying to others, or are those drives actually bad? I have a hard time thinking multiple drives are bad as these WD1003fbyx drives have been rock solid (I have them in 7 other servers)
If this is bad drives, what is the easiest way to replace all the drives? If the backup works I can backup the server, replace all the drives, recreate the volumes, and do the SBS2008 restore. I've done this before with fairly good luck. Not sure if this is the easiest way to do it though so wanted the experts opinion.
