Not my area of expertise. However, I came across the following in a TKE
presentation.
Format your IBM supported USB memory for Trusted Key Entry data (TKE Data).
This suggests that it's some special format and can only be done on a TKE
itself.
It seems for some reason you are trying to load

The easiest option would be to create a new environment and volume(s)
for test and development and IPL to the new volume(s), leaving the
production alone, and disable some volumes if you need to reclaim
space.

Looks like the answer is no to your question.

Although, FENCE=(ACTIVE=YES,VOLUMES=nnn) indicates that JES2 will fence to nnn
volumes in most cases more than one nnn volume can be used in certain
situations such as when spool volumes fill or if the job obtains spool space on
different syste
Food for thought - separate MAS for each environment, but same
SYSPLEX. Though better to have each environment in separate SYSPLEX
and MAS. (That also allows better separation for implementing
changes to each environment.

Has anyone used the SPOOL statement in JES2PARM to set affinity to a
particular LPAR for spool? Apparently, you set spool volumes A, B, C, D
to have affinity with PROD and set E, F, G, H to have affinity with
DEV. This seems to have the effect of "fencing" DEV to certain spool

We have CA-OPS and have put things in place but management isn’t mainframe

Thanks for the responses.

Yes, a JES2 cold start with newly defined/allocated spool and checkpoint
datasets will be needed. Have you looked into setting default estimates in
JES2PARM, bytes, lines, pages, with OPT=1 to cancel jobs that exceed your
limits?

We don't have a plex so I can't answer your question directly, but do you have
any kind of automated console monitoring? We set up a rule so that if test
jobs go over a certain percent of spool space, we just automatically cancel and
purge them, no questions asked. We implemented this after a

Rather than split the spool, (no cold start required IIRC, it might be more
prudent to limit the amount of output a job can create.
Look up $ESTLNCT(?) in the JES2 manual; Set an appropriate Count and specify
option 2.
When the job exceeds the defined limit (more
We have a 3 system plex, with two of those systems, DEV and PROD, in a

a loop and used up all spool. This in turn, caused our PROD system to
come to, basically, a screeching halt.

I've never worked with a TKE, but I've had to plug into HMC's, DS8000's,
and others such as IBM 2421 SKLM's, and I believe I've always had to

I think OSA acts like a switch, so you can share it between Lpars. I do use
z/vm vswitch since we have only one processor on zpdt, but I have sen that
in previous life.

I don't recall the specifics but in Z/os you can define the OSA's and
ports, and depending on the OSA-Express card you have, some have 4 ports
per card, some have only 2, and if IIRC, on a z15 one for one, but you
can share across LPARS defined in your IOGEN, and use a device /

Please explain a bit more what you are trying to do...
Are you trying to share an OSA link with multiple LPARs?
Are you trying to have multi OSA links for a single LPARs use like through a
VIPA?
A switch might not be needed.
Also, what version of Z and z/OS
