Linux / LTFS / Tape Drive archival guidelines

This short guide is a quick rundown on how to set up a Linux system with the necessary drivers and tools to reliably use any HPE LTO tape drive with LTFS for home or semi-professional file archival purposes.

Quick recap for users hoping to use Windows:

There is no hope. The current state of affairs of LTO tape drive support on Windows 10 and up is so poor, that by the time you get it all working, it might no longer work effectively after a single reboot with yet another update of some kind. All in all, Microsoft has permanently broken the Windows CopyFile API for sequential access since 22H2, disabling updates is very difficult, Windows Defender interferes with file access, and Microsoft and OEM drivers for SAS/SCSI controllers are extremely outdated. Just don't do it.

Instead, as expected, we rely on open-source and *nix instead.

 * Broadcom/Avago/LSI HBA/RAID cards are made to be used in servers where there's plenty of airflow (minimum of 200 linear feet per minute (LFM)).
 * These conditions are not always attainable in Desktop PCs without generating a considerable amount of noise.
 * In this scenario, there's a need of constantly monitoring the IOC core temperature to dynamically regulate fan speed.
 *
 * Unfortunately, those idiotic devs at Broadcom couldn't be bothered to add this feature to "sas3ircu" so a DIY approach had to be followed.
 *
 * The IOC has internal sensors that measure the temperature of each core.
 *
 * This very simple PoC displays the IOC core temperature (MAX(Sensor[0->N-1])) for Broadcom/Avago/LSI HBA cards. No kernel mods required.

Byobu (over SSH) Cheat Sheet

I often find myself using Byobu on a Linux machine when connected to it over SSH. In doing so, I've noticed that many of the documented keyboard shortcuts don't work. This can be due to the native PC's OS intercepting certain keys, or possibly other reasons.

Below is a cheatsheet with Byobu features I have found usually work when run over a SSH connection.

Action	Windows + Putty to Ubuntu	MacOS + Terminal to Ubuntu
Help menu	BASH: byobu-config	FN-F1
Create new window	CTRL-a c	CTRL-a c or FN-F2
