How many drives in your storage unit(s)?

Subject: [Veritas-bu] Not all drives appear to be used

I am a Netbackup 6.5.2A user. I currently have 100+ clients that I back up on a daily basis (fulls and cumulative incrementals). I have a Sun/STK SL3000 tape library with 10 LTO-4 tape drives. My issue is with tape drive usage. I have multiplexing and multistreaming turned on for all of my policies. It appears that only 8 of the 10 drives are in use at a time. Also, it is not always the same 2 drives not in use.

Any ideas on why this is? As I write this, I have several jobs queued saying that "required drives are in use", but there are 2 tape drives available.
