Hi,
        We just hooked a qualstar 4222 tape library to our ADSM 3.1.2.50 (on
AIX 4.3.2). The 2 drives are sony SDX-500C (Ait-2) and the tapes are
SDX2-50C. After I moved some data to a tape, ADSM reports that the capacity
of the tape is only 20G:

adsm> q vol 0*

Volume Name               Storage      Device      Estimated    Pct   Volume
                          Pool Name    Class Name   Capacity   Util   Status
                                                        (MB)
------------------------  -----------  ----------  ---------  -----
--------
000000                   AIT-LIBRARY  AIT-AUTO     20,362.0   25.5  Filling

I defined the device class for the library as:
adsm> q devc ait-auto

Device       Device        Storage    Device       Format     Est/Max
Mount
Class        Access           Pool    Type                   Capacity
Limit
Name         Strategy        Count                               (MB)
---------    ----------    -------    ---------    ------    --------
------
AIT-AUTO     Sequential          1    8MM          AITC           0.0
DRIVES

We are expecting at least 50G. I searched the ADSM.org and did not find
useful information. If anybody can give me some hints, I will appreciate it.
