Thank you for getting back to me so quickly. I'm told by Citrix support that the hosts can't see the LVM table information. I'm not sure if that's all that it needs. I'll be working with them shortly, and I guess what I want to know is how to get the most detailed information on the LUN of the target. I've given them everything they can see from the GUI, but I'm afraid they might need more in depth information on the LUN.
You should be bale to query the information from the XEN console using the iscsi adm.
But, I don't think I have heard of Xen needing any LVM info.
You can download the log package from the DSS webGUI, and have a look in the iscsi folder. Here you find the configuration file for each target.
