Although SDSP data sets used during SSM migration cleanup are periodically released when not in use, it is still recommended that you do not run secondary space management when automatic primary space management is running in order to avoid possible contention for SDSP data sets.
Every 30 seconds, level 1 to level 2 migration checks to determine if recall or aggregate backup needs an SDSP data set. The value 30 is stored in the MCVT#CHK field and can be patched to any other desired value.
