Issues using vault to duplicate backups on OST Disk Pool.

Question

Recently we moved our backups to use an OST disk pool off our DataDomains. We had previously just mounted up an NFS export from the DataDomain as a basic disk storage unit and then duplicated our backups with vault to an i2000 library. When we would start a vault job it would split the batch duplications into 6 drives (the number of drive assigned and available for duplications) and everything would be fine. Since moving over the the OST disk pool the batch duplications have been cut to between 1 and 3 jobs even though there are more than enough tapes and drives available to do more. The effect of this is extremely long running duplication jobs that write to one drive. Is there a setting somewhere I have missed or is this a "feature" of OST disk pools.

Thanks.

Is there anyone here who is doing vault duplications from an Enterprise Disk - Disk Pool, and is able to use all available drives. If I know this is possible then I can try and figure out what I am missing from perhaps a config file somewhere.

Thank you in advance.

Thank you in advance.
