LTO-8 tapes are not readable in new library with LTO-9 tape units

Hello community team,

We have a new tape library Quantum I3 with LTO-9 Tape Units. The Auxiliary to Tape is running fine.
Now we have exported tapes from our old Quantum I3 with LTO-8 tape units via the I/O slots and imported them into the new library via the I/O slots.
The tape library sees the tapes, but it cannot read the content: No content found.
I have already tried to run a catalog, but the catalog job shows no activity.
It is noticeable that in the old library the barcodes are displayed with 6 digits, e.g. 002020 and in the new library with 8 digits, e.g. 002020L8.

Does anyone have an idea what the problem could be and perhaps a solution?


 

Kind Regards

Franz-Josef

Hi ​@fjs63 

What does MA logs show?

@fjs63 Are your tape drives LTO-9? LTO-9 drives can read and write to LTO-8.

Does your tape catalog job ends in failure?

I think the job does nothing

@fjs63 The error for block size mismatch is retriable error and once correct block size is identified it should get past it. Are there any other errors where it seems to be stuck?

@Abhishek Narulkar 

Unfortunately, I do not see any other error messages in the CVMA.log
Are there any other logs in which I can see something?

We have changed the barcodes and now everything is fine.
