The 'pool' is what is defined in the DIRMAINT EXTENT CONTROL ..   you must
define there the volumes DIRMAINT will use -- and then create at least one
group of these volumes that minidisks for guests will be assigned from.
 Then you specify that group when you issue commands like AMDISK and
CLONEDISK.   DIRMAINT will attempt to find free space as large as specified
(for CLONEDISK, the source disks size) from the volumes in this group.  You
have to make sure there is sufficient space in the group ..   DIRMAINT will
tell you if not, and fail the request.

Don't confuse the volume addresses for the DASD with the minidisk addresses
for the guests..   A minidisk is not the same as an attached volume..  I'm
not sure which you're using, so want to be clear..  DIRMAINT won't help you
manage attached volumes -- only minidisks.   The minidisks can be fullpack
(1-END - not 0-END) -- but must be minidisks for commands like CLONEDISK,
et al.
