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.
