I have RAID1 set up on a 2008 server. It was working yesterday but this morning it fails to boot to the operating system as it can not find the hard disk. No obvious reason for this so I'm assuming random disk failure.
I have accessed the PERC S100 control panel and noted that it has a status of degraded, with disk 0.0 as on-line and disk 0.1 as Ready.
I have two questions
1. Why is it not booting into the operating system. I thought that that was why it was RAIDed. So when one disk fails the other other still works. Or does this point to second problem?
2. I understand that my best line of action is to replace disk 0.1 which has the status of "ready". Can someone confirm these steps.
a. Powerdown,
b. Repalce disk 0.1 with new disk
c. Delete the virtual disk that is automatically created and initialise disk (I assume it is possible to do all this from the PERC S100 management console as I can not boot the operating system to access the open mange software)
d. Rebuild array.
e. Cross fingers and hope server boots!
I have a backup of data (7 days old) but the time to have to rebuild server would be massive if the data off these disks is deleted. Any advice on best practice for this scenario would be greatly appreciated.
