OK, I'm trying to see how much data we're writing to our LTO2 drive every 

I know I can do a PRTMEDBRM TYPE(*STATISTICS) and this should show me what 
I need. But here's all I see - is there a setting to keep track of the 
Bytes in this report:

5722BR1 V5R3M0 040227                  Media Volume Statistics Report      
        8/05/05  10:55:13   Page

 DAY01A  ULTRIUM2     7/14/05  12/07/04   8/11/05           22          0  
         0            0            0 
 DAY02A  ULTRIUM2     7/15/05  12/07/04   8/12/05           22          0  
         0            0            0 
 DAY03A  ULTRIUM2     7/16/05  12/07/04   8/13/05           22          0  
         0            0            0 

Then there's the "Work with removable media lifetime statistics" option 
from SST's Product Activity Log. Here's what I get with that:

Volume          ---Temporary Errors---   --------M Bytes--------
ID                    Read       Write         Read      Written
                         0           0            1            1
DAY01A                   0           0            1      1342288
DAY02A                   0           0            1      1343949
DAY03A                   0           0            1      1346177
DAY22A                   0           0       192383      1387011
DAY23A                   0           0            1      1120503
DAY24A                   0           0            1      1124678

Well, while I was typing this up, I did see where last night's tape 
(DAY22A above) has 1,387,011 total MB written to it. Tonight's tape 
(DAY23A) has only 1,120,503 total MB written. Considering that 23 and 24 
are both roughly the same, I can at least compare 22 to 23 and see that 
this month I have written about 266,508 MB more to the tape.

I'm just trying to see how much compression I'm getting. So on my 200GB 
native tapes, I'm writing about 250+GB (not going to try calculating the 
exact figure....lol). Sure wish there was an actual way to find out how 
full the tape is getting though because I know that IFS data (I'm ONLY 
saving my Domino Data directories) doesn't get good compression.
