LUN addresses range

bernf — Mon, 20 Nov 2017 18:18:42 GMT

New to the management of a SAN, I have a two P2000 G3 configured as a single entity. When I mapped a volume to a host, I discovered that some LUN IDs were not working. Actually, the mapping went ok but I got problem when I tried to have this volumne discovred by Xenserver. Xenserver replied by saying: "No LUNs were found." In this case I used a LUN ID of 601. I manage to have Xenserver discover this volume with a LUN ID of 51.

How to does the LUN ID works? Is there a defined range of ID that can be assigned? Do someone would have a pointer to a resource I could read to learn more about it?

Thanks,
