Below is a dump from a DotHill SAF-TE compliant enclosure, using SANtools smartmon-ux software. The text in RED indicates the SAF-TE components. This was run on a Windows-based O/S, but the software is ported to Solaris, LINUX, IRIX, AIX, HP-UX, and other UNIX Variants.

SAF-TE: SCSI accessed fault-tolerant enclosures interface specification
(Editor’s note: Below from Intel’s SAF-TE site)
This specification defines a set of SCSI commands for setting drive status information, including status for RAID arrays, into a (SAF-TE compliant) disk drive array enclosure. The drive array enclosure may be a separate enclosure, or the same enclosure. The specification also defines commands for managing hot-swap drive slots and returning environmental health information for a drive enclosure.
The status commands are typically used by the enclosure manufacturer to assert lights or other indicators Read more…
Yes – SES, which stands for SCSI ENCLOSURE SERVICES, is the ANSI standard by which Fibre Channel-attached subsystems adhere to. SCSI enclosures “speak” SAF-TE, which stands for SCSI Accessed Fault Tolerant Enclosures.
The SES specification has a great deal of intelligence, which allows for not only reporting health, but changing fan speeds, manipulating the LEDs, and controlling audible alarms. SAF-TE is a rather dumb interface that reports the most basic information in more of a pass/fail form.
