After compiling ltfs on debian bookworm running in a vmware vm with the tape attached though sasci passthough, I was able to format a tape using mkltfs -d /dev/sg2 -f' When I then try to mount the ltfs tape it does not work saying it can not read the index. Can this be solved? Please see command outputs below for details.

It looks the ANSI label and the LTFS label can be read correctly. So I believe 512KB block cannot be read on this HBA.

Please find out the HBA setting about max transfer length and change to the longer one. In some HBA, it is not existed or implemented with tape support option in HBA.
