We have four CTCs assigned between our production VTAM box, and four more CTCs assigned to the production VTAM 'twin' box (it's other brother VTAM, if you ever watched the Newhart Show).
E.g.
op d net,trl,trle=ctc0v0e
IST097I DISPLAY ACCEPTED
IST075I NAME = CTC0V0E , TYPE = TRLE
IST486I STATUS= ACTIV----E, DESIRED STATE= ACTIV
IST087I TYPE = LEASED , CONTROL = MPC
IST1221I WRITE DEV = 0C52 STATUS = ACTIVE
IST1221I WRITE DEV = 1C52 STATUS = ACTIVE
IST1221I READ DEV = 0C51 STATUS = ACTIVE
IST1221I READ DEV = 1C51 STATUS = ACTIVE
IST1068I PHYSICAL RESOURCE (PHYSRSC) = HASEALS
IST314I END

For testing a new z/VM 5.1.0 system upgrade we'd like to take 0C61 (Read link) and 0C62 (Write link) offline from the production VM/VTAM svm.
After lengthy review of the VTAM manuals, I've not been able to find a command to vary any CTCs (TRL's in VTAM terminology) INACTive.
Anyone know of a good command besides CP DETACH? :-)
From what I'm seeing, I'd guess that if I were to actually use CP DETACH (shudder), any sessions using those CTCs would be dropped, but immediately be able to reconnect using any of the other remaining three pairs of CTCs to the two VTAM host systems.
