In regard to: [Networker] Automatic drive unloading - ?, Len Philpot said...:

I'm curious about something...

In our previous 7.2 production installation, the "Idle device timeout"
library attributes were set to the default of 10 minutes, and that value
was kept through our 7.5.1 upgrade a few days ago.

The 7.5 admin guide states:
"Idle device timeout - The number of minutes before an idle device is
unmounted. This attribute only applies to SmartMedia, Silo, and shared
native jukeboxes with device sharing enabled."

This confused me too.  We had scripted auto-unloading under older releases
because at least with some drive types, it's a bad idea to leave tapes
sitting in the drives all the time.  I've been told by an engineer I trust
that it could actually shorten the lifespan of both the tape *and* the
drive for some formfactors.

Regarding the auto-unloading -- I'm pretty sure that what happened is that
EMC changed NetWorker but failed to update the documentation, so that the
docs no longer match behavior in this regard.
