NAME
     ses - SCSI Environmental Services Driver

SYNOPSIS
     ses* at scsibus? target ? lun ?

DESCRIPTION
     The ses driver provides support for all SCSI devices of the environmental
     services class that are attached to the system through a supported SCSI
     Host Adapter, as well as emulated support for SAF-TE (SCSI Accessible
     Fault Tolerant Enclosures). The environmental services class generally
     are enclosure devices that provide environmental information such as
     number of power supplies (and state), temperature, device slots, and so
     on.

     A SCSI Host adapter must also be separately configured into the system
     before a SCSI Environmental Services device can be configured.

IOCTLS
     The following ioctl(2) calls apply to SES devices. They are defined in
     the header file <scsi/ses.h>.

     SESIOC_GETNOBJ	Used to find out how many SES objects are driven by
			this particular device instance.

     SESIOC_GETOBJMAP	Read, from the kernel, an array of SES objects which
			contains the object identifier, which subenclosure it
			is in, and the SES type of the object.

     SESIOC_GETENCSTAT	Get the overall enclosure status.

     SESIOC_SETENCSTAT	Set the overall enclosure status.

     SESIOC_GETOBJSTAT	Get the status of a particular object.

     SESIOC_SETOBJSTAT	Set the status of a particular object.

     SESIOC_GETTEXT	Get the associated help text for an object (not yet
			implemented). SES devices often have descriptive text
			for an object which can provide information such as
			location (e.g. "power supply left").

     SESIOC_INIT	Initialize the enclosure.

FILES
     /dev/sesN	 The Nth SES device.

DIAGNOSTICS
     When the kernel is configured with DEBUG enabled, the first open to an
     SES device will spit out overall enclosure parameters to the console.

HISTORY
     The ses driver was written for the SCSI subsystem by Matthew Jacob. This
     is the functional equivalent of a similar driver available in Solaris,
     Release 7.
