Intel Modular Server shows all drives twice

Hi there

Just installed our first IMS, and activated the shared LUN add-on. I've created some 40GB partitions for the OS and the remainig 1.6TB I want shared between all servers.

When I look in disk manager though, it shows 2 40GB drives and 2 1.6TB drives. If I look at the properties of the disks they are all called "Intel Multi-Flux SCSI drive" but they have the same name Bus Number and Target ID, but two LUNs, ie.e

Bus Number 0, Taget ID 10, LUN 0

Bus Number 0, Taget ID 10, LUN 1

Not sure why that is happening, but it also shows the doubled drives during the build of the OS when you chose where to install to.

Any ideas what I've done wrong?

Cheers

HI

Do you have 2 x Storage Controllers installed? This is most likely the case. You are probably seeing 2 of each LUNs because there are 2 paths to each LUN. You need to install the Operating System MPIO drivers to mask out the 2nd path.

The MPIO drivers can be found on support.intel.com and then search for the compute module MFS5000SI and look under drivers.

thanks

I do Richard, thanks for that. as I say, first IMS, so these kind of issues are new to me.

Thanks very much for that quick reply!

Thanks - but the "Special instructions" pdf for 2008 server is wrong - it is set up for BIOS 2.7, but we are on 3.x now and the set up is a little different.

Any chance of those Special Instructions being updated?

Thanks

Hi

The setup instrcutions are the same for 3.0 as they are for 2.7.

Are you running SBS 2008 or just 2008? If the former, there is a required workaround to install the MPIO driver.
