[Users] Issues installing iSER initiator on a Scientific Linux 6.4 (OFED 3.5-2) box

[Jingcha Joba]

Can you tell me how you got it to working for 3.2?

The install script clearly checks for

 if ($kernel =~ m/^3\.5/)  {
..
..
            $kernel_modules_info{'iser'}{'available'} = 1;

}

Well, to be honest I am surprised too. I see a lot of issues online
regarding iSER, but there is no proper solution to this. I was hoping
someone over here, might be able to help.
