Theo,
When DFHSM does primary space mgmt. it checks if any of the datasets have
management classes that have Class Transition Criteria parameters coded. If
the do and it fits into one of the criterias DFHSM will try and move the
dataset through the ACS routines (SC, MC and Storage Group) with the
&ACSENVIR of SPMGCLTR. Before this can happen the defined thresholds of
volumes holding these datasets must be met.
