NetBackup 8.3 not writing to tapes

We have an issue where all off a sudden the Media/Master server Netbackup 8.3.0.2 we have will not write to any tapes.

It fires off the job, it says it has selected a tape to mount, I see the tape move in the library into the drive (Can see that on the web gui also), but that is all that happens. It never writes anything to the tape. The tape sits idle in the tape drive and Netbackup just sits there waiting for the tape to be read. 

When using vmoprcmd it shows the tape drives, but does not show that there is a tape in them.

I have upgraded and downgraded the Firmware on the tape drives and library, and it does nothing. Still the same issue. I have checked the drivers and they are all up to date, and none of those have change anyway.

I have removed Microsoft Security patches to see if that will make a change, but that does not change.

It seems that either Netbackup is not reading what is returned from the library/tape drives or the library/tape drives are not sending the load/mount completion back to Netbackup.

Any help would be greatly appreciated.

Thanks

    So we have figured out the issue now.

    When the tapes were inserted they never checked what version of Tapes they were putting in. 

    We took one out last night and had a look ..... LTO8 tapes. Drives are LTO7. So correct, not a netbackup issue at all, and in the great words of Homer Simpson - "D'OH!!!!!"

    So new tapes should be arriving tomorrow and no more issues we hope.

    Thanks all for jumping in to help ou in this.
