Hi All

I have a supermicro Server that has an Onboard Adaptec 2010s Raid Controller.

Initially i put two disks in booted from CD and installed the operating System, All was fine, Then through the management console i added a further Three disks to create a Raid 5, prior to this i formatted the three disks.

Now with all the disk in when i try to boot it says no Operating system found, If i take out the Three Raid 5 Disks it boots into windows server, but whenever i put them back in no matter how much i swap them all around it says operating system not found.

Any idears

John

Sounds like it's trying to boot from the RAID5 volume instead of the mirror.

Check the boot device priority and specify the correct volume.

Also, if you didn't create a mirror before installing Windows you won't have one.

I can't remember if the supermodel creates a default redundant volume if you add the disks.

Check the RAID config on bootup and see how it's configured.

Sorry for the silly question but i have checked the raid propertys and cannot see anything relating to boot priority, unless i am missing it.

The only other booting i have checked is in the bios but that just says boot from harddisk it will not have any info on the raid.

OK, I thought there was a volume option.  I will check later on mine.

I am fairly sure the controller though does do some auto config, can you see what the volume configuration is with all disks inserted in the RAID configuration prior to boot?
