Stefan Rubner finally convinced me to install the iSCSI modules he assembled for the ReadyNAS, onto my ReadyNAS NV+. His software works as advertised, and installation was a cinch after I installed the EnableRootSSH add-on to the NV. I experimented with the iSCSI initiator in Windows 2008 as well as with the initiator of the Linux-iSCSI Project: both behave nicely with the ReadyNAS target. Nice stuff. Thanks Stefan!
