TSM Active Data pool file number

One of the strange features of TSM AD pool is that, when you do first incremental backup (for example 10 files), then change some data (for example 5 files) you’ll get incorrect number of files with query occupancy stg=adpool command. It will show you number of files equal to 15, the same as in your primary storage pool. But if you compare sizes of pool you’ll see a difference.  So do not rely only on file number in your AD storage pool
