We're looking to migrate to a new z/10 and we've come up with an issue that
hoping someone out there knows how to resolve. A while back when we installed
our SVC (2145) we lost the ability to see the "real" LUN number that was being
assigned to our z/VM system as an emulated (9336) device. On the SVC side on
things you see a 16 character LIN id like this; 000000000000013D (which we'd
only use the last 4 of "015E"). When you run the SCSIDISC command on z/VM, the
LUN that shows up in z/VM in just the next number in sequential order (e.g. if
it was the 11 LUN allocated, it would have a LUN id of 000A000000000000). Are
there any commands from z/VM that can be issued to give you the LUN id as
defined within the SVC? A command like "q edev e011 details" shows
