I'm trying to get SRP working on my ConnectX-4-LX cards to see if it
has the same problem as iSER does. When I try to connect the initiator
to the target I get that opensm is not running. I tried all the umad
devices without any luck. I found that someone had to modify the
source to get it to work with RDMACM [0] and then another thread that
specified that an option had to be passed to the ib_srpt module, but I
don't see that option in modinfo and the Readme mentioned in the
thread is not there[1]. If SRP should work, can someone help me figure
out what I'm doing wrong here.
Thank you,
Robert LeBlanc
