[Linux-cluster] problems with iscsi storage and boot order

I have tried both suggestions.  I added the line:
node.session.initial_login_retry_max = 8
I even made the value as high as 20 with no change during boot up.  Then 
I added NETWORKDELAY=20 to /etc/sysconfig/network and I still see:
iscsiadm: Could not login session (err 4)
iscsiadm: initiator reported error (4 - encountered connection failure)

when I boot the machine.  After the machine as booted, I restart iscsi, 
clvmd, and gfs and everything works.  Sometimes I hate computers.

Thanks,
Randy
