"Personally, I'd be taking advantage of the fact that LTO-3 drives can
read LTO1 media"

Guess we are overlooking the obvious, since the generation is supposed
to be able to read the previous two. This would seem to be the most
practical solution. The old tapes in this case should also be made read
only if they are not full already or ready for recycle mode.

Subject: Re: [Networker] Two jukeboxes using same pools

We just did this when migrating from SDLT to LTO in a fairly small
site.. Only a few small tricks needed...

A) Two jukeboxes will need two autochanger licenses.   
B) if you do have more than one library, then nsrjb works slightly
differently, your scripts may break - you can ensure you use -j
{jukebox} always in your scripts and also you can set a cmdline variable
NSR_JUKEBOX to the name of your favourite one...
C) if you set the drives in the old jukebox to be read-only then you
wont have any problems with the system attempting to use the old tapes.

Personally, I'd be taking advantage of the fact that LTO-3 drives can
read LTO1 media (ok that's what the brochure says, does anyone have any
exerience here?) ...   Why not just decomm the old jukebox - put all
your LTO1 tapes on a shelf or in the new jukebox, mark all the LTO1
tapes as manual, and delete with nsrmm when the tapes expire.

Subject: [Networker] Two jukeboxes using same pools

Hello list,

my intention is to retire the old jukebox (LTO1 drives) and replace it
with a new box with LTO3 tape drives. 
Until the retention period for the data on LTO1 media is expired I plan
to attach both jukeboxes to the Networker server.

All backups shall go to the new box, the old box shall be available only
for restore. I guess this should achieve this:
- label new LTO3 media into exisiting pools
- set all LTO1 media to read-only

Is there a flaw in this plan?
Can Networker handle media of the same pool in two jukeboxes in this
way?


Thanks for your time.
