Looks like you are using the wrong port GUID, and so the path lookup
to the target fails.

I suggest using ibsrpdm from my srptools stuff under userspace in
svn.  It's a lot easier to use, since you don't have to guess the LID
of the target, and it tells you everything you need to do.

You can just do "ibsrpdm" to get a summary of all the targets on the
fabric, and "ibsrpdm -c" to get a string you can echo to the kernel to
connect.

This is almost definitely the node GUID, so using it as the port GUID
will be wrong.
