MCS (IBM X345, 2 hard drives ) can't boot after switching hard drives

[master001]

I have installed Unity on MCS(IBM X345, 2 hard drives) W/RAID 0+1.

After I switched hard drives( HD0-->slot1, HD1-->slot0), power on, it shows "... reconfigure...." choose " set as vendor default"

Problem: OS can't boot up.

Any suggestion for that? I do believe it is array/hard drive setup issue.

Thanks.

swapping drives on the same server is never a good idea. If you re-configured it to vendor Default, then the RIAD has been rebuilt from scratch and therefore you must have lost all the content. When you want to replace a drive, you should only remove one at a time, and never swap/change both the drives at the same time.

Thanks again mchandak, you are very helpful.

Problem fixed. Fortunately I didn't rebuild the RAID,I just placed back the HDDs and copy the info. to RAID. HDDs was recognized and OS is running.
