To clarify: ftp is not an option.
Regarding security issues - I'm allowed to read the data on both systems
and I am the RACF guy on both. Last, but not least, it is not production
data. While data security is quite interesting topic, it is not an issue
here.

Don’t read the tapes directly, FTP the contents from one environment to the
other. Separately, Doing what you did is likely a security exposure if you
are not sharing or propagating the RACF permits between the separate
environments, where you have access to the DSN on the local system, but not on
the remote system.

Subject: RMM automatically adds the volumes
The following scenario:
VTS shared among several z/OS monoplex systems. Each system has it's own
set of tape categories in DEVSUPxx.
I had to read multiple tape volumes from other system.
So I temporarily added the volumes to the VOLCAT, disabled "REJECT
ANYUSE(*)" in EDGRMMxx and I read the tapes successfully.
However I noticed every tape volume I read was automatically added to
RMM database, which I don't want.
Q: How to prevent it?
The only method I'm aware now is to stop RMM and reset the subsystem,
but it is not good idea, because some other users should be able to
access the tapes under RMM control.
BTW: a tape must be read to be added to RMM db. I did not read few tapes
previously added to the VOLCAT and those tapes were not added to RMM.
BTW2: I deleted the volumes automatically added to RMM.
