You'll need to install MDSM on the host. MDSM is compatible with RHEL4, RHEL5, and some SLES distros. On CentOS it may or may not work (not supported by Dell, but sometimes it does work).

If you don't have any of the supported distros, I'd suggest to contact your OS support and ask them if there's a way to blacklist certain devices.

(you didn't mention your OS, but as you did mention kernel errors, I assume it's a linux/unix/bsd type OS)

LOL, im not going to install MDSM on every single node connected to it. I only need it on the management node, which i do have.

But yeah, the systems are RHEL 5.

You don't need the management software on every node, but you do need the host software on each node. This gives you the multipathing software (native mpio isn't supported and has a high likelyhood of not properly working when it comes down to needing it (controller failure or so) as well as blocks the 20MB 'disks'.

Well i am actually using the native dm-multipath and rdac. i only have a single controller.
