Explanation: MIGRATIONLEVEL1 is the required
parameter to migrate eligible data sets from all migration level 1
volumes to migration level 2 volumes.
When you specify MIGRATIONLEVEL1 for non-SMS-managed data sets,
two conditions apply:
- If you also specify DAYS(days), DFSMShsm migrates non-SMS-managed
data sets based on the days value.
- If you do not specify DAYS(days), DFSMShsm migrates non-SMS-managed
data sets based on the current DFSMShsm value for the MIGRATIONLEVEL1DAYS
parameter of the SETSYS command.
Defaults: None.
Note: - If you specify this parameter in a direct-to-tape environment,
the command fails.
- If you specify this parameter when level 1 to level 2 migration
of automatic secondary space management is run, the command fails.
