Wrong tape size - Ultrium 960 autoloader
The Ultrium 960 LTO3 Autoloader doesn't determine correct size of LTO3 tape's. Tapes are formatted with a size of 100GB instead of 400GB. Changing the size to 400GB won't work, same result, only 100GB are available.
LTO drive an autoloader are on latest firmware.
Any ideas?

Re: Wrong tape size - Ultrium 960 autoloader
By Default the statistic will always show 100 gigs until you reach the end of the media .. This is STRICKLY for Satistics which are bogus
If Using DP 5.5 with the latest Media Agent, Add the variable
OB2CHECKMACAPACITY=1 in the omnirc file of the media agent hosts ..
The variable goes into the omnirc file
DP_HOME\omnirc ( No extensions for windows )
on HPUX and Solaris, it's under /opt/omni/.omnirc file )
So basically the media statistics will not be guessed by DP, BUt will be returned by the LTO drive instead .. Note the space is always reported in native capacity mode.
Also this only work for LTO Technology
Best regards
Gilles

Re: Wrong tape size - Ultrium 960 autoloader
Are you able to write over 100GB of data to the tapes in Data Protector? (Software support is available at 1800 474 6836)
Hope this helps

Re: Wrong tape size - Ultrium 960 autoloader
The problem is, we WANT to see DP report them as 200/400 respectively.
I have the same issue, and as a consultant I know the situation and can live with it. My customer on the other hand WANTS to see "400GB for his LTO3 tapes.
Supposedly, DP6 was to fix this issue, but it seems it is still lingering around. Will the DP5.5 fix work for DP6? I guess I can try and find out and report.

Re: Wrong tape size - Ultrium 960 autoloader
Since the default size of the Ultrium Media Class is 100GB, you need to override the vaule and specify 400GB.
I did this on a Linux Cell Manager so I would expect it to be similar on HP-UX and Solaris and maybe only slightly more different on Windows.
In the /etc/opt/omni/server/options/global file, scroll all the way down to the section where HP lists the default values for each type of media.
Under that section, add a line (or edit if already there) to tell DP the default...
MC_13=1 36 250 410000000 4
I would think the line could go anywhere in the file, but I put it in the same section for sainness purposes.
Again, this is not fully tested, but the reported format size IS 400.39GB.
Also, if you have a mix of media, I am not sure how this will play out. I think you can just format your LTO2 or 1 media and "Specify" the lower size, but I do not have any to test out.
