Hi Robert

Yes, the capacity is worked out in the Device class entry.  You'd need to show 
us that.

Cheers

Subject: [ADSM-L] LTO7 tape capacity

Hi to all

I think I found the explanation:

ULTRIUM7C - Specifies that Spectrum Protect writes data that uses the ULTRIUM7 
recording format with compression. Only Ultrium 7 media can be written to with 
the ULTRIUM7C format. The average capacity of an Ultrium 7 cartridge when the 
ULTRIU7C format is used is 15 TB.

Hi to all

Hi to all

I add a new library scsi LTO7 , in documentation capacity between 6TB – 15TB .

I run a backup of a client with audio / video files and I got this output

Protect: ADSM2>q vol stg=lto7_2

Volume Name         Storage Pool Name     Device Class Name    Estimated     
Pct Util    Volume Status
-----------------           -----------                          ----------     
                    ---------          -----           --------
ESJ407L7                     LTO7_2                              LTO7CLASS      
             5.7 T                100.0        Full

I was expected to get more capacity ! In client I didn’t have compression 
CLIENT or YES

Did I missed something to define ?

Here the ouput of q stg LTO7_2 f=d
