| + | * click "Discover IQNs" | ||
| + | * now, on the compellent, create a server and try to identify the proper iSCSI initiator. It may not be there yet, in which case you can retry on a per-XenServer basis. | ||
| + | * click "Discover LUNs". If there are no LUNs, go back to the Compellent and try again. If needed, click on Discover IQNs again and retry | ||
