SAFTE(4)                  OpenBSD Programmer's Manual                 SAFTE(4)

NAME
     safte - SCSI Accessed Fault-Tolerant Enclosure

SYNOPSIS
     safte* at scsibus?

DESCRIPTION
     The safte driver provides support for monitoring the various environmen-
     tal sensors present in SCSI enclosures using the SCSI Accessed Fault-Tol-
     erant Enclosure command set.  The hardware monitor is used with the
     sysctl(8) interface.

     SAF-TE compliant devices can provide an arbitrary set of sensors from the
     following types:

           Sensor    Units    Typical Use
           temp      uK       temperature
           fan       RPM      fan
           psu       On/Off   power supply
           doorlock  On/Off   door lock
           alarm     On/Off   enclosure alarm

     Sensor data is updated every 10 seconds.

     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.
