I missed the earlier threads, so I apologize if this is redundant. Make sure
that you check SYSGEN before creating the CSLT that will be used for the
reload. In the IO section of SYSGEN, do a "lvol". The only device that
should be configured is LDEV 1. Any other LDEVs defined will automatically
be included in the MPEXL_SYSTEM_VOLUME_SET and therefore you will not be
able to unmount or scratch them.

To remove LDEVs other than LDEV 1 from the volume table, use the "dvol"
command. Then create the CSLT. After the reload (INSTALL) the only LDEV
(disk device) configured will be LDEV 1.

You'll have to do this AFTER you remove the disks from the
SYSTEM_VOLUME_SET, which is going to require a reload of your system
from tape, you know. This will take careful planning and a chunk of
downtime. Running FORMATVOL or INITVOL on a disk in the
SYSTEM_VOLUME_SET would destroy your system. :)

Since you are doing a reload, you might want to consider implementing
private volume sets, so in the future disk changes like this maybe
aren't so disruptive.

In any case, once you have the system back up with the proper disks
removed from the SYSTEM_VOLUME_SET, then you can access them with
VOLUTIL and wipe them.
