Ok, if multipath is grabbing the HBA device so I'm unable to mount it, that's fine, I will go with that. So I re-enabled the iSCSI initiator so that the NIC device would become active and I can see if multipath will grab both of them. No luck, but I'm ahead of where I was previously, so here's my status. In dmesg, both of the devices are being found on boot... HBA- scsi1 : qla4xxx QLogic iSCSI HBA Driver version: 5.01.00.08 QLogic ISP4032 @ 0000:14:01.1 hdma+, host#=1, fw=03.00.01.24 Vendor: EQLOGIC Model: 100E-00 Rev: 2.3 Type: Direct-Access ANSI SCSI revision: 05 qla4xxx 0000:14:01.1: scsi(1:0:1:0): Enabled tagged queuing, queue depth 32.

There's some references to sdc (although [faulty]) that I don't understand, but maybe it will help troubleshoot? My multipath.conf is setup in accordance with http://kbase.redhat.com/faq/FAQ_51_7170.shtm . Thanks, Scott
