Hi, I did a little test of active-only pools and they do have inactive files in them. The way they differ from ordinary pools is that during reclaim all inactive versions will be squeezed out, whereas with ordinary pools only expired versions are. Except at the very start of the AOP implementation there will always be inactive versions. You just can't reclaim that quickly.
You copypool will still have inactive version too unless you reclaim it aggressively. The feature is mis-named; it should be 'almost active-only if aggressively reclaimed'. I hope someone else will run some simple test of this. When I did mine, query contents of the volumes showed the inactive files until the reclaim was done.

In reading up on the new TSM V5.4 feature "Active-Only Storage Pools" it looks like this is now a reality. I could create an Active-Only storage pool (limited to backup data, no archive data). This new pool would now become my new destination pool for my backup storage pool command. I could even go one step further and choose to collocate this data by node. The end result would be a set of tapes at DR that would not have to skip over any files when performing a restore. I realize great consideration has to be done before implementating something like this because if the active file is corrupt you wouldn't be able to recover a previous version. Still, in the case of DR I know I have many customers that would accept the risk in order to reduce the amount of data they have offsite and to speed up their restores. I know that you can set a tape in an active only storage pool to offsite so I'm assuming that it will be included with move drm. I still haven't completed testing myself yet though. I'm wondering if anyone out there is considering this as well? --------------------------------- Sucker-punch spam with award-winning protection. Try the free Yahoo! Mail Beta.
