Not if LDEV 3 is in the MPEXL_SYSTEM_VOLUME_SET.....right?
You can maybe boot from tape at this point in order to run some utilities from
a Support tape....

You didn't explicitly state otherwise, so I am going to assume that Ldev 3 is
in the MPEXL_SYSTEM_VOLUME_SET. If that is true, is it not also true that if
you cannot get that drive back online you will have to perform an
INSTALL since you won't be able to fully mount the MPEXL... volume set?
Which of course means doing a full RESTORE?

This has never happened to me (fortunately!) so I am not *positive* you are in
as dire straits as I am suspecting.
