ok, CentOS5 box, with 2 qlogic fibre cards. The 1st is connected to an EMC Clarion box which I setup using a nice step by step, powerpath s/w so when I was done I had the device listed as /dev/emcpowera1 and powera2. They are mounted, working great.

We just added an additional storage box (an ArrayMasStor by ADTX). It uses a java virtual console to configure, so the box is now set with 2 luns (no raid) but I can't figure out how to (publish for lack a better term) the drives as mountable. I do want to 1st create a software raid 1 on them before I mount it, but not sure on the next step. The qlogic card diagnostics (scli) sees them, here is some card output;

HBA info:

So, the card see the 2 different lun's, but I don't know how to say;
1. create a raid 1 between them
2. mount the new device.

As I mentioned, the EMC once completed left 2 devices which made things, easy, but does anyone have experience, and / or some help on this.

Thanks as usual to all replies.

Does the kernel see them?

cat /proc/scsi/scsi

If so, they should be listed by fdisk -l as something like /dev/sde, /dev/sdg, etc. At that point, the disk is seen by the OS and the HBA has done its part.

Open up your favorite partitioning tool and create your partitions.

You can search RedHat docs for examples.
