You probably want to evaluate something a little newer - RHEL-4.2 was
released some time ago and there have been significant fixes and feature
enhancements in the releases since that time.

I use software-based iSCSI on pretty much all my test systems - it works
great. You need the iSCSI initiator package installed on the systems
that will import the devices and an iSCSI target installed on the host
that exports the storage. There are several target projects out there in
varying states of completeness and functionality. I've used iet (iSCSI
enterprise target) on RHEL4 and there is now also stgt (scsi target
utils) which is included in the Cluster Storage channel for RHEL5.

RHEL5 also supports installing to and booting from software iSCSI targets.
