My 2 cents.  


I ran into this when I added my stkl700.  My master server is Solaris 8.
I was only getting a few mb on an lto3.  I patched the OS and it
resolved it.  Again, my 2 cents.

Just curious. Is the tape that's not full actually MARKED as full?  Or
is it just that NBU is choosing a second tape for other reasons
(database backup, different retention, etc)?

It could well be. My concern is that LTO2 should be at least 200GB and
400GB Compressed. so if you are getting nothing like that, its either
the tape, drive, drive configuration issue perhaps.

 

LTO3 offers 400GB / 800GB Compressed - LTO1 Is 100GB / 200GB compressed.

 

Can you definetely confirm its an LTO2 tape (sorry if it sounds silly to
ask, but it seems to be alot of "wasted space" if its LTO2).

        Windows fileshare data. Word, excel, Visio, text and image file
formats. 
        
        I'm currently writing to a different tape using the same drive.
Maybe the fujifilm tape is the problem.

        I'm having a case of the "Mondays". On Friday i upgraded to MP4
from 6.0MP3. The MP4 upgrade seems to have gone well. 
        
        A backup this weekend only used 125GB of tape and then required
a 2nd tape. I should get closer to 200GB of data on an LTO2 tape. The
tape positioned itself to file 1. 
        
        I'm wondering, why didn't more data get written to the LTO2
tape?
