Trouble Mounting LTO-5 Tape
on Aug 7, 2018 at 4:30:50 pm

Hi Guys,

I'm having a little bit of trouble in mounting a tape in our Quantum LTO-5 Half Height Model B tape decks at the moment (connected to an ExpressSAS H680 via SAS cable). I've downloaded the latest LTFS package from the Quantum website and installed the ICU Framework and LTFS software along with the latest update for FUSE, I've downloaded the latest firmware/drivers for the H680 card and flashed it using the ATTO Config tool and updated the firmware for the tape decks using the Quantum xTalk software. I've also tried multiple SAS cables so this isn't the issue either. I am running on a High Sierra Mac fyi.

When I issue the ltfs /mnt/ltfs -o devname=0 command via terminal, it comes up with this process:

QFSHARE:~ admin$ ltfs /mnt/ltfs -o devname=0
307 LTFS14000I LTFS starting, QUANTUMLTFS Standalone version 2.2.2, log level 2

I have a feeling that due to the mac being recently updated to High Sierra, all of the permissions have been reset and this has caused a lot of issues. I'm not entirely sure as to how I go about making sure that I can open the permissions up on this administrator account so that I can mount up the LTO 5 tapes and also copy data across without any issues occurring with that.

Any help that anyone would be able to give me would be HUGELY appreciated as I'm currently trying to set this up for a video production company in London, UK.

I don't think you'd get that far if it were a high sierra security issue. Most likely the new software Quantum made didn't really cater to the model B (HP) drives.

I would suggest trying the demo to YoYotta and see if that works.
