We have also tried changing the port settings from Loop, to NPIV, to Auto on the d2d device but the results are the same. Unfortunately all HP's documentation is directed towards windows users, who simply use a GUI to discover the virtual drive. > To configure (i.e. speed and connection type) and control the QLogic FC > HBA I recommend to install the QLogic SANsurfer CLI. Ok, I may try this but I had hoped the default settings would work. We have no problem talking to our SAN on the same fabric, from other hosts with Qlogic HBAs. > Do you use port zoning or WWN zoning?

I've double-checked the zone and refreshed it several times but no dice. I have a ticket open with HP, but their support folks seemed a bit stumped as well. /sigh...
