SCSI Environmental Services
Driver
SYNOPSIS
ses* at scsibus? target ? lun ?
DESCRIPTION
Theses
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
<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.
