I don't know the exact algorithm, but it does round robin the use of
drives.  If it chose drive1 last time, it will choose drive2 the next
time.

Subject: [ADSM-L] How does a library choose a drive?

TSM Server 5.3.3.0

This is probably not a TSM specific question, but hopefully someone can
point me to the right place to look.
We would like to understand how the library decides which available
drive to use. Does it always start with the first drive defined and look
until it finds one that is available?  The answer may depend on the type
of library.  Any help is appreciated.
