Issuing a @LOADLIB REFRESH appears to work, but it took the tape drives offline and did not put them back online - they remained offline.
When the LOADLIB REFRESH command is entered, MIM executes the contents of the
The default is NONE.

If no member is coded on RESTARTSYNCH, no VARY commands entered at restart.

Restart manager is described here
The RESTARTSYNCH statement itself states
(Optional) When running under Restart Manager, the SYNCH member is used only during the initial startup. For managed restarts, the member specified through RESTARTSYNCH is used instead;
RESTARTSYNCH=NO means that no commands is issued.
If you wish to run the same set of commands as during initial synchronization, specify the same member name for both SYNCH= and RESTARTSYNCH=.
There is no connection made in the doc between startup/restart and RESTARTSYNCH, which is described here:
