DP 9 - Cannot format LTO6 Tapes

Hi all,

We have just upgraded all of our LTO4 tapes to LTO6 tapes. We have an HPE MSL 4048 Tape Library (firmware up to date) with a LTO6 Tape drive.

Successfully added to Data Protector 9, and also scan tapes normally. But when trying to format tapes we are getting an error.

Here is full session output

Re: DP 9 - Cannot format LTO6 Tapes

Hi,

Create debugs and have support check the sense info logged into the MMA debugs.

Are you formatting brand new LTO6 media or are you trying to reformat old media? I seem to remember LTO is typically backward compatible 2 generations for reading and only 1 for writing. But I may be wrong with this, didn't double check. Anyway, if you're trying to format brand new LTO6 media then just generate the debugs so support can check what is really going on here.
