iscsi volume seen as read only 32K ram disk

I have readynas with several iscsi volumes defined and they are all working fine. Yesterday I wanted to create a new volume to install opensuse 12.1 under vmware workstation 8, but after creating the volume and using the iscsiadm command to define and logon to the volume when I use Yast Partitioner - it shows up as a 32K read only RAM disk even though it’s defined as a 45GB iscsi volume. Running up todate opensuse 11.4.

Any suggestions on a possible root cause ?
