Hi Tom and all,
Our AIX is 4.3.3.0 and TSM server is 3.7.3.0.
I have concerned about changing the tape device format setting, does anybody
have such experience?
Appreciated your help!
Thanks,
Phillip

DRIVE is supposed to work the same as 3590E-C (I said below 3590-C, but
3590E-C is the correct value).
What level of ADSM are you using? I think it was 3.1.2.30 or .40 that
added support for the 3590E drives.

Hi Tom and all,
Cool! I'll change it to get big capacity.
What will happen if I change the setting? It is a production system and
have
about 1TB data on it.
Thanks,
Phillip

We use the following definition for the device class:
ANS8000I Server command: 'q devclass 3590*'
Device Device Storage Device Format Est/Max

Name Strategy Count (MB)
--------- ---------- ------- --------- ------ --------
------
3590E-256 Sequential 5 3590 3590E- 0.0

So instead of "DRIVE" I specified 3590-C and as you can see, one tape
above has 143 GB (compressed) data on it.

Question: We set the device fromat to be 'DRIVE' which means use the
highest
format that it supports, does it mean it uses HW compress? Form the 'q
vol'
output, it seems it uses as 40GB. How do we 'turn on' the HW compress
if it
is not compressed? Thanks in advance for your help.
Best regards,
Phillip Guan
