Dear Andreas,
Thank you for your post and I am happy that you found the information we
provided is helpful.
Yes, I believe that the problem was caused because the capacity of the tape
is not correctly counted. Unfortunately, we can only change the registry
entry ("MediaCopyTolerance") to adjust the default 5% limitation to 2%. The
only solution is to figure out the why the capacity is incorrect.
I still suspect that the problem is due to the third party drivers. I
checked our database that found some similar issues where third-party
drivers do not report correct tape capacity information to RSM.
As we have discussed before, RSM cannot reserve special drives for special
applications. It may conflict with the usage of the Veritas Backup Exec. So
I suggest that we test the library in the new server to see if it works. I
will wait for your test results.
Thanks for your time and efforts. Have a nice day!
Regards,
Joe Wu

|Dear Joe,
|I've read the article you mentioned below and now I
|understand why our Tapes are set to "recall-only", even if
|only 3GB of Data had been moved to tape.
|If our System for what reason ever thinks that the tapes
|have a capacity of 7.99EB, then 75GB or 100GB free on the
|Tapes means, that this is less than 5%. In fact it's
|0,0000...%. So the system acts correct to set the recall
|only flag, because it thinks the tapes are nearly full.
|Now the question is, why does the system think a 160GB
|Cartridge has a capacity of 7,99EB. Is there an overflow
|in a ?integer Value? because the Tape has a capacity
|larger than 128GB? Is it possible to check that?
|In the meantime I've upgraded our System to SP4 updated
|the driver of the Library (now 1.05) and driver and
|Firmware of our sdlt320 Tapes (now 2.2 and v70).
|With that environment I'll do further testing until our
|new Server arrives. I'll keep you up to date with the
|results.
|It would be great if you could find something about the
|7,99EB Problem or a solution how to patch the registry to
|enable remote storage not to keep 5% of the media free.
|Your Hints are very good, thank you.
|By the way, it was never a problem to create media copies.
|Regards
|Andreas Kleinschmidt

|>|the
|>|>|tape to recall only after the process of storing Data
|to
|>|>|it.
|>|>|2.) As we got the Library, we had too few scsi cables
|so
|>|>|we run the library with only 2 drives cabled, though
|all
|>|4
|>|>|drives had been in the library and had been recognised
|>|by
|>|>|it. But as I tried to start rsmconfg the tool wasn't
|>|able
|>|>|to configure the library in any way. After connecting
|>|the
|>|>|rest of the drives it was possible to configure the
|>|>|library. So maybe it is necessary to configure all 4
|>|>|drives for the use with removable storage. As I
|>|mentioned
|>|>|above we have only configured two Tapes. So maybe the
|>|>|library isn't complete for whatever part of the
|Software
|>|>|and the malfunction is due to that.
|>|>|3.) The other things I think about are even more
|>|>|incredible so I better don't write them down
|>|>|Unfortunately we aren't free to gamble around with the
|>|>|equipment. The free Server Space is so low, that it
|>|isn't
|>|>|possible to restore the complete Data to the Disk and
|>|>|start again. Also we can't connect the library to
|>|another
|>|>|Server for a longer test period, since Data Backup and
