RAID1 not working..

04 Nov 2009 11:11AM

Hi guys.

I've got a poweredge T300 Server with a simple 2 disk RAID1 setup and I was trying to test the RAID by pulling one drive then booting off the other.  The first drive works, however, when the bottom drive is unplugged it won't see a bootable device, which suggests that all the data is on just one of the 250GB SATA drives.

I have checked the Open Manage Software and it says there is a RAID1 and shows both hard drives ok.  Any ideas?

Hmm...I've never quite understood why many people read threads and simply don't help out, surely the idea of a forum is to read the posts that you know you can help out somebody with and then at least reply? Hmm

In theory the server should boot from either disk in a failed state but it may not. The server looks to boot from drive 0(default)  unless it has been changed. If drive 0 is removed and you cant boot from drive 1 then just change the cables over, change 1 to 0  then it should boot.

Hi Tommo,

 

Sorry about the delay in replying buddy, I appreciate the reply.

It did indeed work moving the cable over from the working hard drive to the 'non-working' drive.  Is there any way around this to automate it for the client or is it simply the limitation of not having a PERC installed?
