NAME
     safte - SCSI Accessed Fault-Tolerant Enclosure

SYNOPSIS
     safte* at scsibus?

DESCRIPTION
     The safte driver provides support for monitoring the various
     environmental sensors present in SCSI enclosures using the SCSI Accessed
     Fault-Tolerant 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.
