MSL2024 parallel writing problem

Hi
I have a HP MSL2024 library with two tape drives. When I submit two jobs in the Oracle Secure Backup home page I see that backups run concurrently.
but when I login to HP storage msl2024 tape library webpages I see on the system status that always one of the drives is writing. Never both. For example. For a few seconds drive 1 has status writing, the second drive status is idle, for the next few seconds both drives are idle and for the next few seconds the first drive is idle and the second is writing. So backups don't run concurrently but in turn and very slow.
What could be the reason of such behavior?? Is a problem with configuration of the HP tape library or somthing else??
thanks for help

Re: MSL2024 parallel writing problem

You installed OSB on Windows, UNIX or LINUX?

Can your operating system detect the library and tape drives?

When you start the backup, does the 2 drives show as "device in use" ?

Re: MSL2024 parallel writing problem

- OSB is installed on Linux
- Operating system detected correctly both drives and tape library
- When I start one backup only one device is in use, when I start 2 backups both devices are in use.
