Multipath w/ Emulex on HP blade

With QLogic cards I can run set_parm and configure multipath so that I only see once device file for each LUN (even though there are two paths.)

Is there something similar I can do with Emulex cards (I am on BL25p.)

Officially HP FC cards by Emulex does not support multipath in Linux...
You can try to use Device Mapper, introduced in lates Linux releases, as described in "Linux Device Mapper Multi-Path Configuration Guide for HP Arrays for Early Adopters":
