Hello. Timely subject for me as I have just begun using LTO-2s and LTO-1s. I
was a big DLT users for years, still am but not with Tivoli.
Note.. assuming of course, one must remember that if you are compressing the
Tivoli backup data on disk, when it gets to tape, even if you are
compressing on tape, the tape won't compress very much???
Then on this note, I am curious why when I defined my LTO-2 and LTO-1 tape
types, I specified LTO2C and LTO1C which should compress up to 400 GIGs for
an LTO2 and 200 GIGs for an LTO1. But my q vol shows 200 GIGs and 100 GIGs
used at FULL. Anyone else see this or comment.
Tks

Subject: Re: Cartridge Estimated capacity
Relatively simple. The "EST CAP" is set when you define the DEVCLASS,
probably 80GB in this case (see line for tape 000034). When data is then
writtent to the tape, the EST Cap is updated to the ACTUAL capacity
when the tape gets FULL. This may be higher or lower than the value
in the defioned devclass.
The tape will show the original EST Cap while FILLING until the amount
of data exceeds this value. Then it increases as data is added
until tape is FULL.
The tapes that show FULL but have a pct Util less than 100 are
mostly tapes had some of the data expired since they became FULL.

Hi to all
Can anybody tell me why the huge difference between the numbers of
Estimated Capacity of a full cartidge DLT8000 (40/80 G). The format of the
devclass was configure to DRIVE.
The nodes are backup without compression .
Here the output of the q vol.
Volume Name Storage Device Estimated Pct Volume
Pool Name Class Name Capacity Util Status
