Experimenting with backupsets. I understand that TSM treats the backupset as one file, and discovered that it mounts all the volumes before sending data.
What I don't know is, what is TSM doing when it's mounting the volumes? Is it verifying the integrity, or availability of all the volumes? Is it cacheing the data? I actually cancelled my session before it finished reading all the volumes. So I didn't get any data. Does it remount the volumes a second time to send the data? Thanks John Johnson
