open-iscsi: iscsid errors

[kikawala]

I'm attempting to attach a 2TB LUN over iSCSI to my Gentoo box. I basically followed this guide: http://en.gentoo-wiki.com/wiki/ISCSI#Co ... 8client.29 Below is what I am getting.

tail -f /var/log/messages

Feb 23 14:55:47 charon iscsid: iSCSI logger with pid=2982 started!
Feb 23 14:55:48 charon iscsid: transport class version 2.0-870. iscsid version 2.0-871

Feb 23 14:57:00 charon iscsid: connection1:0 is operational after recovery (1 attempts)

The connection errors and connection recovery repeat endlessly.

The ping timeouts repeat endlessly and randomly will show the below in dmesg and then the ping timeouts continue. I can ping the ISCSI Target successfully

I am able to attach this LUN to a Windows box and can partition/format/read/write to it. I also have a different target node on the same SAN which is connected to ESX successfully. I tried a 1TB LUN as well and I still get the same results without the "Very big device" informational message.

Any help would be greatly appreciated.
