By default without -d option, ibsrpdm will use
/dev/infiniband/umad0 -- with corresponding to port 1 of mthca0

This is correct by using srp-mthca0-1; however, I got this
from your previous email which you reported *I am seeing the
error “ Got failed path rec status -110 ” on Linux console*
echo
id_ext=200300A0B811C847,ioc_guid=00a0b8020022cd27,dgid=fe800000000000000002c9020022cd26,pkey=ffff,service_id=200300a0b811c847
> /sys/class/infiniband_srp/srp-mthca0-2/add_target
You used port 2 of mthca0 here ie. srp-mthca0-2; therefore,
you got pathrecord failure
Please retry:
0. Make sure you connect port 1 of host hca to target (since
you connect them directly. Port 2 work as well but you have
to use the umad1 and srp-mthca0-2 for steps 1,2 below)
1. ibsrpdm -c -d /dev/infiniband/umad0
2. echo whatever target discover to srp-mthca0-1
