Question Raid 1 rebuild problem

I have an IBM Xeon XSeries, with RAID 1
and 2 HDs SAS
, with RedHat enterprise

I got problem with 1 disk (yellow alert in the disk)

I took off the problematic disk,
Booted the Cpu with just 1 disk (good disk)

Controller - POST OK
Controler says "found just 1 HD" - correct

No boot

I work a long time with Linux Admin, but I am a beginner in RAID 1 troubleshooting

Please advise me.

Doesn't RHEL have official tech support, hence the "Enterprise"? Well, whatever, on a software RAID1 one of the disks is the boot disk, the other, the mirror. Apparently, your primary disk was the removed disk. Go into the BIOS and switch the boot order and you should be back in business.

I hope it was the hardware raid not software so RHEL will not bother about it....Just check the BOIS settings.
