Hi,
I have tried the RMM manuals but, once again, I can not find what I am
looking for. So, I hope that one of you will be able to help me.
We have been asked if it is possible to retain a tape file for five years
AND one year after the last use. So, if the file had been used three days
before its five years original expiration date, it would keep for another
year starting that use. And, id during that additional year it was used
again, then, new reset to the expiration date. This would be a COUNT(1825)
plus a REFDAYS(365), which, I think, it is not feasible.
Your help, as usual. will be highly appreciated,
Regards
Jack
I would consider deeper change.
You don't have to keep the tape. You need to keep datasets.
Just keep them on disk, then use DFSMShsm to migrate it. And backup.
Then all the parameters reside in the Management Class.
Pros:
easier to maintain
no dependency on tape devices (VTS, physical ATL), volume size, etc.
users need not to have any knowledge about tapes
you manage datasets, not volumes. Some VRS constructs are related to the
fact you have to keep or scratch whole volume, while you want to protect
datasets.
better tape utilisation (not as important in virtual tapes)
no more multivolume issues
