SAFTE(4)

🦋 SAFTE(4) — the SCSI Accessed Fault-Tolerant Enclosure girlies have arrived

okay so real talk, this is a page from the Kernel Interfaces Manual, and it's about safte — say it with me, bestie, SCSI Accessed Fault-Tolerant Enclosure 💅 she's giving hardware monitor main character energy and honestly? obsessed.

🌸 DESCRIPTION 🌸

so the safte driver is literally the designated bestie for monitoring all the environmental sensors chillin' inside your SCSI enclosures, using the SCSI Accessed Fault-Tolerant Enclosure command set 🫶 and the hardware monitor is used with the sysctl(8) interface — iykyk.

SAF-TE compliant devices can provide an arbitrary set of sensors from these types, no cap:

• temp — units uK — temperature 🌡️
• fan — units RPM — fan 🌀
• psu — units On/Off — power supply ⚡
• doorlock — units On/Off — door lock 🚪
• alarm — units On/Off — enclosure alarm 🚨

sensor data is updated every 10 seconds — so like, refresh queen, but make it ten seconds ⭐

💖 heads up bestie: an enclosure may provide environmental information using an alternative to the SCSI Accessed Fault-Tolerant Enclosure command set used by this driver. enclosures using the SCSI Enclosure Services command set may be monitored by the ses(4) driver — so if your enclosure is that girl, go say hi to ses(4) instead 🧚
