Formatting fails on HP LTO6 drive v2.4.5

[vguilleaume]

Describe the bug I try to format a LTO6 media and i have a failed error in return.

The context is : HP ULTRIUM 6 drive, and openltfs v2.4.4.1 and openltfs v2.4.5.0.

This is something not usual for me except when with some HP drives. I do believe that the tape library manufacturer upload there own firmware in the tape drive even if it is a HP.

In have seen that a bug was opened in 2021 about a similar issue with HP ULTRIUM 6 tape drive, it is why i decided to upgrade from 2.4.4.1 to 2.4.5 version. Even after the migration, i have the same error message even i understand that the fixed provided should be in 2.4.5 version.

Could you help me to confirm this ?

Thanks @jgreen24 for your update,

Sorry for the confusion, i had in mind that the version https://github.com/LinearTapeFileSystem/ltfs/tree/v2.4.5.0-10502 included this fix.

Then i believe, only master has this fix ?

[jgreen24]

That's right @vguilleaume, at the moment only master has this fix included.

Going to close this, please use master for this fix. Feel free to reopen the issue if you have any other questions!
