Enclosure Services Viewer (SAF-TE)

Top Previous Next

SAF-TE enclosures are the equivalent of SES enclosures, but for SCSI-attached hosts. Unlike SES enclosures, SAF-TE enclosures have a unique SCSI ID and LUN associated with them. The internal mechanism and commands that SMARTMon has to use to determine the health of a SAF-TE enclosure are different from those commands used to communicate with a SES enclosure. The net result is the same, however.

SAF-TE is the name for a specialized command set that is used to manage and sense the state of the power supplies, cooling devices, displays, indicators, individual drives, and other non-SCSI elements installed in a SCSI enclosure. If you have a SAF-TE-compliant enclosure, this software can decode and report this information.

Unless you have a very inexpensive enclosure, chances are good that your enclosure is SAF-TE-compliant. If you are not sure, invoke the -E+ option and find out. Below is sample output from one of our enclosures when we unplugged one of the power supplies and ran the program on a Windows XP machine.

Terminating program.

The text in RED printed as a result of the -E+ option. The rest of the text printed because the -I+ option was also selected.

•

If you invoke the -E option, the program will run in the background and poll your SES compliant enclosure(s) at the same time it polls disk drives. If a problem is found, it generates an alert as specified by the command-line options. If you invoke the program with the -E+ option, all of the current enclosure information will display and the program will terminate.

•	There are additional informational fields that this program can report, providing your enclosure manufacturer reports that information to the SAF-TE electronics in their engine.

•	If your SAF-TE enclosure supports the optional SAF-TE power-on minutes or SAF-TE power-on cycles data, we report that as well starting in revision 1.27.

•	Version 1.28 added SAF-TE reporting capability for additional slot and array status reporting.

Below is the output that one might see in a log file or email alert before and after unplugging a power cable.
