[ewg] OFED 1.2-beta1 SRP multipath test results

[Chieng Etta]

Hi Ishai,

Hi Ishai,

I have attached the log file on sles10 x86 and the steps to test failover
and failback.

I also tested on a sles10 x86_64 system today. The multipath failover and
failback were working fine.  However, after recovering the failed path, the
log file showed "remaining active paths: 1".  Is this correct?  
I did the same steps on RedHat and the log message was "remaining active
paths: 2".

Thanks,
Etta

Hi Chieng,

Thanks for the tests.
In my tests the fail back works.
Could you please describe the way you checked the fail back.
Will it be possible to send me the /var/log/messages file.

Thanks
Ishai
