safteSCSI Accessed Fault-Tolerant Enclosure


safte* at scsibus?


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.
