to determine if you need to run TMSXTEND with PARM=RECOVER, you need to review messages that TMSXTEND issues to see if the automatic recovery already took place.
The 2 messages which highlight this are :
AUTO-RECOVER FUNCTION STARTING. Reason: To return to a functional state, TMSXTEND will terminate in error and start a recovery process. Action: None. This message is informational.

If the signal to switch to the new TMC has not yet been given to all CPU's sharing the TMC, it will rename and return the old TMC to its original status, updating any control records necessary. If the signal to switch to the new TMC has been given to all CPU's sharing the TMC, it will finish updating any control records necessary.
