Fred, if the users' data is already compressed (ie BACKTRACK data) coming
in it is quite possible to get only this much. You don't say, but are
these K or J carts? In my experience with J carts I was getting 12-60 gig
per cart depending on the data, with an average around 18G.
Also I think I'd change your devc setting to format=3590E-C. A format
specification 'drive' is supposed to take the highest capability of the
drive, but I've been bitten by this more than once.
Est capacity has nothing to do with how much can fit on a cart.

One of my users has a special project to backup 800 Gb for a few days and
then throw it away. Since we've just cleaned the test machine to put up
V4R2, I agreed and let him have the test machine for 3-4 days. The machine
is configured just like production, in particular the DEVC=TAPE:
Device Class Name: TAPE
Device Access Strategy: Sequential
Storage Pool Count: 7
Device Type: 3590
Format: DRIVE
Est/Max Capacity (MB):
Mount Limit: DRIVES
Mount Wait (min): 60
Mount Retention (min): 2
Label Prefix: ADSM
Library: TSMLIB
The drive is a 3590-E, which experience shows will hold 50-100 Gb,
depending on compression. I put 30 new cartridges into the 3494, whcih
should have sufficed him with room to spare.
However, what I'm seeing consistently is a tape being marked full at
18.5-18.8 Gb. It appears that all the files are pretty much the same size,
and there are lots of them. But what can I do to get more onto a volume???
