Monika, I need to know more about your current implementation with CA-1 to provide a complete answer. You say you have multiple LPARs, are these linked in a JES3 complex with JES3 Global system and 1 or more Local systems? Does CA-1 today modify the IATxxxx messages to overlay the 6 character SCRTCH/PRIVAT text with a 7 character pool name? Which virtual tape solution are you using, and can it be tailored to look for the pool name at the end of the fetch/mount message?
The best way to handle scratch pool selection with JES3 is to use IATUX71 - a JES3 installation exit created by JES3 development for use with tape management systems but designed with me for rmm specifically. When this is used (via the USERMOD provided with rmm) JES3 knows the message text is updated and makes the text updates itself in IAT msgs and in the tape drive display via MSGDISP. The updates are limited to be max of 6 characters when overlaying the "volser", but can be longer when added to the end of the msg. The rmm I&C Guide has information about setting up rmm with JES3, and does provide some various options to get what you want. as well as the JES3 chapter, look at MNTMSG and VLPOOL in the parmlib chapter. If each JES3 LPAR is independent, ie not in a JES3 complex, you can easily get what you want. In a JES3 complex the same pool definitions must be used on all systems because JES3 fetch processing occurs on the Global and tape mounts must happen on each individual system.
