Hi Adsmers,

I have some strange things that i don't understand under ADSM NT
3.1.2.20 with my robot which is a 9714 STK (6 x DLT4000):

the DLT4000 is able to write in 2 mode :
  20 Go : native write
  40 Go : compressed write

1) when a client has the compress option, did Adsm de-compress data
when he receveid it ? (or did it store  it like that in storage pools
disk ?...)

So if data in storage pools disk are already compressed, the DLT4000
will not compress very good after of course !!

2) in the device class options, i put :
  DLT for "Device Type"
  DRIVE for "Format"
  40Go for "Est/Max Capacity"

but i can change the "Format" option by put 20c instead of DRIVE.

The problem is when i look the storage volumes, volumes have storage
like :
 40960 Mo   47  %   Filling
 19500 Mo   52,9%   Full
 18352 Mo   100 %   Full
 etc...

So, the problem is i don't know if Adsm calculate the storage with 40
Go or with 20 Go with compress..!..

Any idea of it ?

Chris
