I have a 3583 L72.  I use the I/O door option so I only have 60 slots for tapes.
Over the last year the slots have been filling and I can see, not too far in the
future, all the slots will be populated and TSM will begin using the "overflow
area" option.   We have no 2nd/3rd shift operators, and I do most of the TSM
'work' at night.

I currently have reclamation set to 65%.   I question some of the policy
retention numbers. but may not be able to do anything with them immediately.
What reclamation percentage seems reasonable here?...dropping to 55%-60%.
Change policy retention values would help some.

We migrated from a 3494 with lots of tapes to a small LTO.

Any suggestions will be appreciated.
