We are currently using a StoreEdge L280 Multichanger tape unit to backup via
Amanda v2.4.1p1.
What OS on your tape server?
When switching on hardware compression on the tape unit, Amanda seems to
override this setting switching hardware compression off.
Amanda does not do that kind of thing. It must be something in the OS
or hardware that's changing the setting.
One possibility is that you are not using the correct tape device name.
On many OS's, the name encodes the density and compression options.
You might also look at the E-mail archives for Subject exb210 changer
patch. That person had a similar problem with a different device.
In general (if it's not a device name problem), I'd probably insert
some kind of script call into your Amanda changer code (whatever you're
using) to reset the options after a tape is loaded, or something along
those lines.
