[ewg] OFED 1.2-beta1 SRP multipath test results

[Chieng Etta]

All,

 

SFW has tested SRP multipath functionality with OFED-1.2-beta1 and here is
the system information and results.

 

Initiator: rh4u4 x86_64 and sles10 x86, OFED-1.2-beta1

Target: rh4u3 x86_64, IBGD-1.8.3-rh16, Areca-1220 controller

 

Failover works on rh4u4 and sles10 with either 2 IB connections from
initiator or 2 IB connections from target.

However, failback only works on rh4u4 and not sles10.  Forcing path failback
by using multipath command also does not work.
