Two things that I'd observed: should one be using /dev/sgxx rather than /dev/stxx? I'm afraid LTFS uses sg backend, not st... Another thing is the fact the tape was formatted as a 12TB one, and not 18TB. Is that correct?

I came to add that I had built the code adding switches "--enable-buggy-ifs --enable-lintape" to the configure call.

Hello, thank you for responding!

I believe the reflection of a 12TB volume is because my blank media is an LTO8 cartridge.

Per your suggestion I reran mkltfs and lfts using sg0. Same results and line by line messaging as resulted from using st0. [I've come from CentOS where the st devices were used.]

It looks your HBA MegaRAID might not support transfer length count at all. I believe this HBA only supports block device, but supports RAID. But I'm not sure this supports streaming device correctly.

8fc7 LTFS30252I Logical block protection is disabled.
8fc7 LTFS30216W Length mismatch is detected. (Act = 4096, resid = 0, resid_sense = 4016).

My recommendation is to use HBA that IBM says supported. Please visit the SSIC provided from IBM and choose a correct HBA.

Hi @TulioLazarini , Sorry for my missing something.

From the lines like below, I think --enable-buggy-ifs highly likely works as @smccue2019 said.

8fc7 LTFS30216W Length mismatch is detected. (Act = 4096, resid = 0, resid_sense = 4016).
