Old SAN with new Windows 2003 server

I had a W2K server with a Compaq RAID Array 4100 device attached.

I recently upgraded to windows 2003. It sees the disk, but under disk manager it is offline and volume isn't available. I tried reactivating the disk, but it didn't work.

Any thoughts out there?

I'm saying that either the W2k3 drivers for the controller are not good enough to let the OS see the drives as it should (a common fault still with W2k3) or the server hardware is not passing the commands in a correct format for w2k3. w2k might have let it go. More likley is the OS drivers imho.

Can you give me the model no. of the controller and I can check? Have you looked on the HAL in M$ website?

Also, it could be a timing issue. Make sure the disks are all powered on a spun fully before powering up the server. (maybe that is too much sucking eggs but worth a mention)

The SCSI controller on your server... is this driver supported under Windpws 2k3? Your server may need a BIOS update as well, although this is less likely.

Hope this helps

it's actually a fiber controller - it's all the same hardware - and worked on 2K but you are saying that perhaps under W2003 it may need a bios upgrade?

this is an old Dell SC600 server

Hmm..I see only W2k drivers on their site.
Maybe not supported.

its purely a driver issue, once u have the correct driver loaded just right click on scsi under device manager and do rescan and then check in disk manager it works.

But I don't think Compaq / HP has an updated driver for this device. In addtion, it's not scsi connected but fiber channel.

There actually is a SCSI RAID controller in the SAN itself.
You may need to flash the controller firmware.
