setting up several STGs on our Server ( adsm3.1.2.40) I only have one STG with
(Client) Collocation - this is the only one which shows up 'clusters'
between 2 and just 4 ... This Pool just consists of 2 Clients ( Solaris -
multipurpose FileServer, client-compression turned on ) and at the moment
has 19 3590e Volumes / 3 Mio Files
- the reclamation threshold is at 50 % and it runs without problem -
I just believe it has to do with the number of Clients, kind of Collocation
in the STG and at last with the total-number of tapes in that pool ...
