Raid1 volume not showing in windows 2008 server

Hi there,

I have a new Supermicro server (8027R-TRF+) with a Intel RS2WC080 raid controller (this is a rebranded LSI 9240-8i). In the server are 5 Samsung Pro 256Gb SSD's. These are setup as 2 * Raid1 and a hotspare. I am trying to install Windows 2008 essentials server. But during the setup I install the raid driver it can't find the drives anymore. If I change the bios setting "Launch Storage OpRom Policy" from "Legacy only" to "UEFI only" it finds the drives after loading the driver, but the drives aren't visible in the bios, so can't boot from them. Windows then gives an error before installing.
Does anybody know how I can get these to work?

Thanks,

Roger

Are you installing from CD media? Are you doing this locally at the console, or remotely via some out-of-band management capabilities?

I've seen some very odd things happening with Win2k8 installation where once, it would simply fail during installation saying the CD is not available despite detecting the CD initially - i was then doing this remotely via the iLO.

Once I've attempted installation physically next to the server, it just worked flawlessly. To be honest, i've only seen this once in my life so I don't expect this to be your problem - but you never know!

Also, is there any BIOS update available? This also does sound like your motherboard doesn't like the SSD drives.

Another thing to try is to try detect whether this is more likely a RAID drive issue, or Motherboard issue - do you have the same problem if you don't use RAID at all??

The server is not yet in production so I am sitting just next to it. The cd is an USB cd player attached to the server. I also tried to install win7 with the same problem, so it seems to be the server and/or raid controller.
I'll try to configure all disks as jbod and see if it can find the disks.

cool ... will wait for feedback then.

If it works as jbod, I would say it is either the raid controller on the motherboard or the lack of drivers - which could mean both the same things actually. Hopefully you could update the BIOS or replace the motherboard should that be the problem.

Nope didn't find it as jbod or Raid0 either. BUT, I tried to downgrade by using this:
MegaCli -adpm0flash -f imr47.rom which is the previous firmware version. This worked and now the drives are recognised in Windows. It's now expanding files ;-) . This took me 2 days to figure out :-( and it could be 1 hour if it was possible to downgrade just using the firmware packages by Intel.

Yes,
It was one of the first things I tried, but using the official firmware packages it says: "Same or older version" and falls back to dos. I then stumbled on the megacli while reading about changing the Intel RS2WC080 to an LSI 9211 IT controller using megacli. ;-)

Thanks,

Roger

Turned out to be a firmware issue of the Intel Raid controller.
