SCSI Enclosure Services (SES & SES-2) Management

December 30th, 2008 No comments

SCSI Enclosure Services, referred as SES or SES-2, depending on the revision level, is a 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 fibre channel or SAS (host-attached) enclosure.  Intelligent enclosures that connect to the host via a SCSI cable will normally speak the SAF-TE protocol.

The command set is defined as an ANSI specification, and utilizes the SCSI commands to obtain configuration information for the enclosure as well as reprogram it to light external indicator LEDs or audible alarms to inform the user about the health and maintenance information for attached RAID controllers and disk drives.

Where can I get firmware updates

Disk (tape, autochanger, whatever) firmware is intellectual property, and is owned by the manufacturer and/or a particular OEM that purchases the peripheral from the manufacturer.

In general, don’t bother calling Seagate, WD, or any of the other drive vendors and ask them for the firmware update.  Unless somebody posts otherwise, it is almost onheard of that they will just send it to you.   You typically need to get that from the company that sold you the hardware.
