Maybe this is because we are using LTO8 tapes....?

For that error message, the ibm documentation gives a really helpful recommendation: call ibm. Do you have an alternate tool for formatting LTO8 tape, like the LTFS Manager GUI? I'd be curious if an LTO8 tape formatted via something else would mount properly.

haha. yes, we saw that.
We haven't tried an alternate tool. Where do we find this LTFS Manager GUI? The Quantum one appears to only work for LTO 5 & 6

I was able to track down Quantum's LTFS Manager GUI and get it set up. However, we're still having the same issue. I can format a tape, but it won't mount. Would this indicate an issue with the computer we're using (Newest version of the Mac Mini) or possibly a hardware issue?
I can send a log in a bit.

Hi, did you ever find a solution? Having the same problem running a Qualstar Q24 robot from a new Mac Mini with ATTO FC-82EN card. Same ULTRIUM-HH8 drives as well.

Looks like setting the ATTO Maximum I/O Transfer Size to 1MB fixed the problem for us.

Thank you, @matthew-mclaren, for reporting! Do you use an ATTO card with a Mac mini?

@retokromer, yes, I have the Mac Mini in a TB3 Sonnet server chassis and have the ATTO card in there.

Ah, I understand. Thank you, @matthew-mclaren! (We work with Mac mini and external ATTO ThunderLink converters.)

I can confirm that using an IBM desk with their software I got the useless “A length mismatch is detected.” error as well.

We still haven't solved our issue. We're using a mac mini with a High Point RocketStor 6661A-mSAS2

@lawrenceaj, did you see the discussion at LinearTapeFileSystem/ltfs#184.

I also encountered this problem where the drive automatically initializes a new tape when it is inserted (In my drive: IBM LTO5), and if you interrupt the process, the tape can be irreversibly damaged, and never formatting successfully.
Terminal return error: Cannot reset the capacity proportion: backend call failed (-20603)

@matthew-mclaren how did you set the ATTO Maximum I/O Transfer Size to 1MB? I am getting the same error on Mac Pro 5.1, cant mount LTO 7 tapes all of a sudden.

commented on June 18, 2024
@Hloni-ux , there is an option to set the Maximum I/O Transfer size in the Atto Config Tool on the "Advanced" tab.

@BleakleyMcD The process of finding the tapes and mounting them was reworked. I'm going to close this, but please test and re-open if needed.
