I was going to tell you to wait, my application depends on that second printer!
But even on a Friday, I could not. ;-)

As was I. I though I tie off the thread for the curious. As suspected by Skip
and others, single-member warm-start removed these devices from each member in
a rolling IPL, thus a successful sweeping of some cosmic debris. I cannot say
whether a hot-start would have sufficed.
For the record, we removed several dozen printers, e.g.:
PRT(nnn) CLASS=ccc,...
two REMOTE definitions, e.g.:
RMT() DEVTYPE=tt,LUNAME=,...
R(nnn).PR(n) ...
R(nnn),RD(n) ...
R(nnn).PU(n) ...
and DESTIDs for the RMTs:
DESTID() DEST=NnnnR
I know there is a $DEL DEStid, but since we had to IPL for the others, I just
let these roll off with the lot. Since this experiment, I intend to follow up
with:
1) RCF against the JES2 Init & Tuning Ref to clarify the minimum requirement
for removal of such definitions
(again, add and modify are spelled out, but I am wont to find such explicit
description for delete)
2) RFE against JES2 to provide $DEL commands for other devices where
possible/practical, such as PRTs and RMTs
