NAME

     sesd -- monitor SCSI Environmental Services Devices

SYNOPSIS

     sesd [-d] [-t poll-interval] device [device ...]

DESCRIPTION

     sesd monitors SCSI Environmental Services (or SAF-TE) devices for changes in state and logs such changes changes to the system error logger
     (see syslogd(8)).	At least one device must be specified.	When no other options are supplied, sesd detaches and becomes a daemon, by default
     waking up every 30 seconds to poll each device for a change in state.

     The following options may be used:

     -d      Instead of detaching and becoming a daemon, stay attached to the controlling terminal and log changes there as well as via the system
	     logger.

     -p poll-interval
	     Change the interval of polling from the default 30 seconds to the number of seconds specified.

     The user may then use getencstat(8) to get more detailed information about the state of the over enclosure device or objects within the
     enclosure device.

BUGS

     This is something of a toy, but it is better than nothing.

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 gen-
     erally 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 <scsipi/ses.h> (q.v.).

     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 sub-enclosure 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 tell you things like location (e.g, "left power supply").

     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.
