You can build the DISKDUMP.TELESUP group on the
MPEXL_SYSTEM_VOLUME_SET, and diskdump files can span
multiple disks/volumes w/o problems. They would not
need to reside on LDEV 1.

But:

Since the only way to do a VSCLOSE of the MPEXL_SYSTEM_VOLUME_SET is
a =SHUTDOWN, any changes to your dump-to-disk files would require
extra downtime, which is not very practical.
