Incrementally restore a subset of SGC volumes

PH44217 introduced incremental restore capability to Production but is currently an "all or none" approach.  

We believe there may be scenarios where specific volumes or applications might be affected by corruption and so we would like to have a simple way within GDPS to select which volumes which will be restored back into Production from the recovered SGC tertiary volumes.

    Useful for forensic recovery. Isn't something like this already in the pipeline with IzBR ? Either way, if restoring individual volumes, we'd have to ensure that they could only be varied online to an existing system for analysis and not inadvertently become part of a now-inconsistent recovery copy that we'd try to IPL from. Addressability of all these copies may also be a challenge.

    It could be useful, if it work well with catalogs

    how would this work with catalogs and mixed SMS pools?

    Nice to have, but it depends on the storage (sms) setup if it is useful or not.

    For example what about consistency against data on other not restored volumes (multi-volume, catalogs, log files, overflow pool). It can be usefull for foreign systems.

    I agree with this need. we retain LCP captures even if some volumes may be missing due to capacity issues because we believe that "half a loaf is better than no bread". In other words, a surgical recovery is probably a more likely scenario that a full DASD loss. This should be a med to high priority for LCP

    I guess I do not see the benefit unless you have separate consistency groups. How will you know what volumes, if it is a multivolume dataset, and then the catalog restore to match? just recover everything into the "clean-room", and then selectively restore back into production what you would want.

    Does this not mean you actually have different consistency groups?

    This sounds a very interesting idea. This will save time and space during a crisis

    This would provide a useful hal-way house between all-or-nothing and true surgical recovery, and I can think of use cases too.....

    would be interested to prioritize this idea, that enables more surgical recovery, instead of 'all or none'
