The following steps remove all data sets from an ML1 volume that
includes an SDSP:
- Remove all migrated data sets from the ML1 volume using the FREEVOL
command. The data sets will select a target volume using the same
selection process DFSMShsm uses during migration. Small data sets
that move to another ML1 volume may go into an SDSP data set. The
FREEVOL process cleans up data sets in the SDSP in need of scratching.
- Verify that all valid data sets are out of the SDSP by using the
following command:
LIST dsname SEL(VOL(ml1volser) SDSP) TERM
If there are
data sets in the SDSP that do not move and are no longer wanted, try
to delete them. It is important that you do not leave the control
records for a data set in DFSMShsm’s system when you delete the
SDSP.
- Delete the SDSP data set using IDCAMS.
- Check the ML1 volume to verify the SDSP and all user data sets
have been moved off the volume. Use ISPF 3.4 or the LIST VTOC command
to display the data set list for the ML1 volume. If the ML1 volume
contains BACKDS data sets, automatic backup should be run on the primary
DFSMShsm host to move them to a backup tape.
- DELVOL the ML1 volume from each DFSMShsm host and remove the ADDVOL
for the ML1 volume from each startup parmlib. The DELVOL command is
issued as follows:
HSEND DELVOL ml1volser MIGRATION
The former ML1 volume is no longer associated with DFSMShsm.
