Check the logfiles
/var/log/messages
Open the file /etc/ietd.conf and change the
domain , in the reverse order , for example com.oracle.com
And restart the iscsi again.

If this fails with the iscsi_module error , please change the grub.conf file
and make sure the default kernel is "not" SMP Kernel.

Start the kernel without the SMP mode ( Openfiler Release 2 (Beta1) (2.6.9-34.EL))

Change the grub.conf file with the correct entries.
