You can use the SETMIG command to control migration for specific
data sets, groups of data sets, or volumes. The control you can exercise
is to allow all migration, to allow migration only by command, or
to allow no migration. For example, if you issue the following command:
SETMIG VOLUME(GP0002) NOMIGRATION
no
migration can occur from volume GP0002 until the SETMIG command is
reissued to allow migration or until DFSMShsm is reinitialized. The
SETMIG command for volumes and data sets is not normally included
in the ARCCMD
xx member. The SETMIG command
for levels (groups of data sets)
is typically
included in the ARCCMD
xx member.
