Since you are using the same destination copypool, even if your mount limit is 3, it's could be waiting for the same output tape (not a drive). TSM will try to stack copypool data, unless collocation is activated.
Also, you normally would not want to occupy all the drives; most shops want to keep a drive available for (a) restore requests, (b) daytime backup jobs, (c) unanticipated drive failure or other maintenance chores (like checkout/checkin and triggered db- backups). BTW, if you really wanted to find additional drives, they can be found on the used market; many customers are dumping their old 3575's to move up to LTO or 3590... have your local IBM rep. refer you (else check the used marketers out there).

However, if you do a "q devclass blah f=d" for the devclass that is your tapepool, what is the "Mount Limit" defined as. It maybe less than 3. Most people have it set to "DRIVES", therefore making it the same as your number of tape drives. David Longo >>> [EMAIL PROTECTED] 08/13/02 11:45AM >>> Hi, Experts, I have a little 3575 L18 tape library attached to TSM on AIX. As I have only 3 dirves on it (strange..), I tried to issued 'backup stg tapepool copypool' and it gets 2 drives. Now that I have only 1 drive left, I issued 'backup stg diskpool copypool' thingking that copying from diskpool to copypool (tapes) would need only 1 drive. But, it says still 'waiting for mount point'. Does it mean that anytime I issue the command 'backup stg', it will use 2 drive at a time? I tried to buy more drives, but IBM withdrew 3575 library from market. Any tips for searching for used market? Thanks for your help as usual.
