Multipath , iSCSI and the MD3000i

[Matthew Geier]

  I'm having terrible trouble actually getting multipath failover to 
work with an MD3000i on RHEL 5.2.

  I can talk to the array fine, but I have no path redundancy - if I 
reboot a controller or pull one of the LAN cables, the machine hangs on 
access to the filesystem that was being accessed via the now missing 
path, it doesn't swap to the alternate controller.

  I've got multipathd running, multpath -l shows multiple paths, but 
fail-over never actually happens.

  If any one else has some ideas i'll post the multipath config and the 
path output.

  I'm assuming there is something wrong with the path selection.
