[openib-general] srp trouble on RHEL4 U4

[Mirochnick Natalia]

I've changed the string as you've advised, but it didn't work. The only 
difference is that string "" was added in /var/log/messages.

root@[...] echo -n 
id_ext=0000000000000001,ioc_guid=00066a01380001de,dgid=fe8000000000000000066a02600001de,pkey=ffff,service_id=0000494353535250,io_class=ff00 
 > /sys/class/infiniband_srp/srp-mthca0-1/add_target

root@[...]  tail /var/log/messages
Oct 18 14:01:26 ... kernel:   REJ reason 0x0
Oct 18 14:01:26 ... kernel: ib_srp: Connection failed

By the way, in ofed srp_release_notes.txt hasn't been said that io_class is 
mandatory parameter.

The problem is with the echo string you are giving. The command should
be invoked as:

echo -n id_ext=0000000000000001,ioc_guid=00066a01380001de,dgid=fe80000
00000000000066a02600001de,pkey=ffff,service_id=0000494353535250,
io_class=ff00 > /sys/class/infiniband_srp/srp-mthca0-1/add_target

You were missing the 'io_class=ff00' bit.

Let me know if it works.
