Does NW actually act on volretent, or is that just a handy attribute field for us to query on with 'mminfo'?

I've always thought that NW looks at the ssretent and/or clretent times to determine the status of a save set, and then identifies the tape as recyclable once all the save sets are recyclable AND none has any dependencies.

But that said, I read some older postings where some folks had experienced problems with older releases wherein NW would base the volretent value on the most recent ssretent for any save set on the tape and not the most recent clretent. Seems it went back and forth a few times with sundry releases.

But even if you had an older save set on the tape, and you changed its clretent time to a newer date, then NW should also change its ssretent, unless it's expired, in which case you could make it nonrecyclable, and then that would do it, so why did it matter in older releases if NW based volretent on the ssretent time and not the clretent time?

Thanks.

George
