.Sh NAME
.Nm safte
.Nd SCSI Accessed Fault-Tolerant Enclosure
.Sh SYNOPSIS
.Cd "safte* at scsibus?"
.Sh DESCRIPTION
The
.Nm
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
.Xr sysctl 8
interface.
.Pp
SAF-TE compliant devices can provide an arbitrary set of sensors from the
following types:
.Bl -column "Sensor" "Units" "Typical" -offset indent
.It Sy "Sensor" Ta Sy "Units" Ta Sy "Typical Use"
.It Li "temp" Ta "uK" Ta "temperature"
.It Li "fan" Ta "RPM" Ta "fan"
.It Li "psu" Ta "On/Off" Ta "power supply"
.It Li "doorlock" Ta "On/Off" Ta "door lock"
.It Li "alarm" Ta "On/Off" Ta "enclosure alarm"
.El
.Pp
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
.Xr ses 4
driver.
