Hi, we're currently having a big challenge installing some SAS cards into a Server 2003 installation using HP G7 380s.
When we originally installed the servers using the HP SmartStart process it found the drivers automatically as "Smart Array Controller", when using the SmartStart on a second set of servers it doesn't find the drivers.

Any ideas?

Just a bit of further information, they are HP SC08e cards, and when installing we still see "HP MSA 2040 SAS SCSI Enclosure Device" under Other Devices in device manager

Sounds like the drivers for the SC08e cards are installed or you wouldn't see HP MSA 2040 SAS SCSI Enclosure Device. I can't see the SCSI Enclosure Services driver for that device on HP's web but it's only a null driver anyway, you can just disable that device, it's a dummy LUN that shows fan/PSU status but it's not used or needed.

Can't see any disk devices on the MSA? You have to go into the web GUI (SMU) and create logical disks and then use host presentation to present each LUN to the host, MSA2040 is shared storage, you may have a Windows node and a linux node connected to it and if Linux connected to the Windows data it could scramble the data so host presentation enables you to mask off LUNs from specific systems so only the right HBA sees the data. It's just like iSCSI and fibre channel in that respect.

Okay, a bit of further info:
We have two systems connected to the san, to do a simple cluster.
We have created 2x LUNs on the MSA successfully
Server A can see both LUNs (albeit it sees 2x copies of each LUN, MPIO issues)
Server B can see neither LUNs.
Cabling looks fine on the MSA control panel (ie 4x ports connected and communicating, 2 for each)
You mention about masking - is this on by default, or is there something we need to do extra there?

You've only mapped the LUNs to one host, Create a host group with both the hosts in it and map the LUNs to that, this video will help.

We gave this a try, but gave up on this one to be honest. It is working okay on a single channel per card, so that's good.
