F.Y.I
We read your question and it seems in your case that it was your choice to
use the bigger robot.
In our case the entire design was made by sun they sold it to us and we  now
hae been fighting for 6 months to get a working license from sun for the
remaining slots.
They do not feel responsible for their design (they already have their
money) and as a result we don't meet our S.L.A.
Thanks for the question we will surely try the res file workaround we saw in
the answers to your request.
Hope that works because our customer is very @#$@#$% about it.

Subject: [Networker] How to get a 40-slot Autochanger license to work for a
42 slot library?

I'm not sure if this will work, but I have a 42 slot Quantum M1800 (two 
M1500s stacked)
tape library with a 64 slot Autochanger. I have an snode managing this, 
running 7.2.2 on Linux.
I'll bite the bullet on the 64-slot license if there's no way around it, 
but I'd really like to get this to
work with a 40 slot license to save cost. That way we could upgrade a 32 
slot license we no longer
need to a 40 slot for the Quantum and then upgrade the 64-slot license 
to a 128 slot license for a new library.
This would be a big savings, I don't care about giving up two slots. 
Those last two slots are fixed slots that
can be used for data cartridges, but are usually reserved for cleaning 
cartridges, and I don't let NW do the cleaning.

To test, I added a 40 slot temp license (exp date = Mar 15, 2008), 
removed the permanent license, stopped and restarted everything.
When I try to mount tapes, NW complains with the following:

Jukebox 'rd=snode:M1800' failed: The jukebox 'rd=snode:M1800' is not 
properly licensed.  Make sure
the jukebox is properly enabled and authorized.

A soon as I re-added the 64-slot license it started working properly - 
no restart required. Well, this didn't surprise me.
The jukebox config lists the physical slots as 1-42, but I do have 
available slots listed at 1-40 because when I originally
configured the library I told NW to reserve slots 41-42 for cleaning. I 
later switched to doing cleaning on the library.
I tried clearing out the 'Cleaning slots' field, but that didn't resolve 
this issue. NW still lists:

41  Cleaning Tape (17 us
42  Cleaning Tape (29 us

in the mount window (nwadmin).  If I run 'changers -ldv' on the snode, 
it reports:

[email protected]:Vendor <M4 DATA>, Product <MagFile>, Revision <12.0>

         1 MT Element(s) starting at address 32
        40 ST Element(s) starting at address 192
         4 DT Element(s) starting at address 128

I've not tried removing the jukebox and reconfiguring it with nsrjb. I 
think when I originally configured
it, I hadn't first enabled Cleaning on the library for those two slots.

1. Should I try removing the jukebox and reconfiguring it now that the 
library is set to see those two slots
as cleaning slots? Might that work?

2. How about if I run nsradmin and then change the physical slots from 
1-42 to 1-40? I've never tried that,
but I don't think it's possible in nwadmin. It does appear editable in 
nsradmin, though?

3. If that won't work, could I shut down NW on the primary sever and 
snode and then manually edit
the corresponding res file 
(/nsr/res/nsrdb/06/001a00fb000000000000000044d20f130a5aeb07)?
This appears to be an ASCII file. Then restart everything? Would that be 
a quick way to test it?
Don't want to risk corrupting anything so just asking first.

Would appreciate any suggestions.

George
