[rhelv6-list] Seeing only ONE session/device instead of TWO

[Prashanth Sundaram]

Hello,

 

I am having some trouble with ISCSI to work on  RHEL 6.2. It currently
is using 1 nic to connect to SAN and shows only 1 session instead of 2.
I have configured TWO nics(em3 & em4) to perform multipathing and have
verified that both can connect to SAN.  

 

Any ideas how to get multipath to work? I only see 1 device instead of 2
in multipath. Please see my config below.

 

Another strange thing is that the iface_name has different MAC address
than what ifconfig shows.
