[openib-general] SRP not detecting

[DiDomenico, Mike]

I'm trying to get an OpenIB system connected via SRP Initiator to an SRP
Target on a SilverStorm 7000 Vfx switch.  When I try to detect the SRP
initiator through the switch it doesn't show up.  Is there anything else
that I need to do to get the switch to see the initiator besides
modprobe ib_srp?

 

You can see what's happening from the output below, which I believe is
being caused by there being no map in the 7000.  I haven't tried adding
it manually yet, but I'm curious why it doesn't auto-detect...

 

thanks
