AW: AW: server-to-server copy-pools

Hi ,

in a first aproach, I changed the following settings :
   data-source-server :
        copy-pool device-class (server device class) : mount-limit set to
'2'
        client-settings for client-node (node-type 0 server) : mount-limit
set to '2'
   data-target-server :
            device class for primary pool where data goes in : mount-limit
set to 'drives'  (==> max = 8)

Then I tried to do to stg_pool-backups in parallel ( they should go to the
same copy_pool) and I got the following error :
        
06/12/02 07:49:13 ANR8340I SERVER volume BC0ADSM1.BFS.023860953 mounted. 
06/12/02 07:49:13 ANR1340I Scratch volume BC0ADSM1.BFS.023860953 is now
defined in storage pool COPY_POOL.

STORAGE POOL running in the BACKGROUND completed with completion state
FAILURE at 07:49:29. 
06/12/02 07:49:29 ANR1214I Backup of primary storage pool BACKUP_VMS_DISK to
copy storage pool COPY_POOL has ended. Files Backed Up: 0, Bytes Backed Up:
0, Unreadable Files: 0, Unreadable Bytes: 0. 

For me it looks as if both backups want to write to the same tape ( because
collocation on copy_pool is 'off' ? ), and
because both requests come from the same "client"-node the second request is
refused. On target server there are no messages. 

Is there something mis-defined or what's wrong ?

Thanks for help

Christoph
