I am testing VMware ESX 3i and DSS LITE in my lab. I've created iSCSI volume in DSS LITE and let VM ESX 3i connected to DSS LITE. When I tring to add storage to VMWare, I found that VMWware displayed "Unable to read partition information from this disk".
Try going in to Console screen and enter CTRL + ALT + W then select Tuning options then iSCSI daemon options and select iSCSI volume type use the File I/O mode.
