I've searched around to no avail, so I hope this hasn't been beaten to death. I'm new at this, so please forgive my ignorance - I wish to correct it.

I've created my LPARs, configured the pair VIOSs to point said LUNs at their proper LPARs, and I see them RedHat installer screen, except twice.

How do I go about ensuring that I only see each volume once? Do I not worry about it during the install and then configure them once the OS is installed, ensuring that I only use each volume once, or is there something I need to do in the RedHat installer before I go and partition and format the volumes?

What else in nessesary... um, it's on a p6 590, VIOS version 1.5 and the target OS is Redhat Enterprise 5.

Dual VIOS?
What SAN storage and device drivers on the VIOS?
How many pathes would you expect the client LPAR to have to the LUNS?

Interesting.........will definitely keep an eye on this thread.

From an LPAR, he would only see two paths, one from each VIO server.

One only one of the two VIO servers, drop to the root prompt with oem_setup_env and do an "rmdev -l" on the virtual device:

rmdev -l LPAR_BOOT

Install with one path, then run cfgdev/cfgmgr on the VIO server to bring back the second path.

Now you can configure your MPIO driver at the LPAR.

Simple.
