So, I have this new NEOs T48 with two LTO7 drives. I thought it would go pretty smoothly getting it
set up, as I have three NEOs T24 LTO6 libraries running with Amanda, each on a separate server. But,
I'm finding it virtually impossible to get amtapetype happy with the compression / no compression
status of the drive / tape. At this point I'm using Amanda 3.3.6. I've built 3.4.5, but have not
installed it yet.
Here is my latest attempt, working with a new, never been loaded, LTO7 tape. I should note that I
have a page in my server notebook from July 2014 showing almost this exact sequence of commands when
setting up my LTO6 library.
Bottom line is that tapeinfo tells me compression is off, it's a new tape, then amtapetype tells me
compression is on.
