Hello,
First make sure that you created the tape library via jb config correctly, 
i,e multiple paths to the server and storage node have been properly 
configured, in your case 10 multiple paths.
Below is the exaple of first tape drive getting ready for DDS and sharing 
over storage node, you need 10 of this.
Drive  1, element 256
Device path 1 ? \\.\Tape0
Device path 2 ? storagenode1:\\.\Tape0
Device path 3 ?

After you have made sure Tape0 on MS is TAPE0 on SN and everything is 
working, you should check and make sure that unique drive ID for each of 
the Tape drive were assigned, i.e unique hardware id for the above drive 
is "ADIC - Drive 1" you should see 10 of this, onnce this is confirmed and 
you are able to mount lable tapes etc from the storage node, make sure you 
use correct drivers,i had hell of a time getting shared enviroment to work 
because a certain version of IBM tape drivers that works fine on MS when 
configured with DDS\sharing enviroment constantly reported Tape busy 
errors.
Any way, last part is to 
make sure any clients you wnat backed up setup correctly, in my case, i 
created unique group and then assigned each client in it to backup to 
Storagenode  ( Look at preferences TAB, where it says storagenode, you 
wanna see, storagenode1 ( my storagenode name) listed instead of 
nsrserverhost. This will tell the networker to direct that client to the 
storagenode server, try it out, i am pretty sure if everything else is 
correct you missed this step.
