.Nd SCSI Environmental Services Driver
|
|
.Sh SYNOPSIS
|
|
.Cd ses* at scsibus? target ? lun ?
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm ses
|
|
driver provides support for all
|
|
.Tn SCSI
|
|
devices of the environmental services class that are attached to the system
|
|
through a supported
|
|
.Tn 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.
|
|
.Pp
|
|
A
|
|
.Tn SCSI
|
|
Host
|
|
adapter must also be separately configured into the system
|
|
before a
|
|
.Tn SCSI
|
|
Environmental Services device can be configured.
|
|
.Sh IOCTLS
|
|
The following
|
|
.Xr ioctl 2
|
|
calls apply to
|
|
.B SES
|
|
devices.
|
|
They are defined in the header file
|
|
.Aq Pa scsi/ses.h
|
|
(q.v.).

|
Used to find out how many
|
|
.B SES
|
|
objects are driven by this particular device instance.
|
|
.It Dv SESIOC_GETOBJMAP
|
|
Read, from the kernel, an array of SES objects which contains
|
|
the object identifier, which sub-enclosure it is in, and the
|
|
.B SES
|
|
type of the object.
|
|
.It Dv SESIOC_GETENCSTAT
|
|
Get the overall enclosure status.
|
|
.It Dv SESIOC_SETENCSTAT
|
|
Set the overall enclosure status.
|
|
.It Dv SESIOC_GETOBJSTAT
|
|
Get the status of a particular object.
|
|
.It Dv SESIOC_SETOBJSTAT
|
|
Set the status of a particular object.
|
|
.It Dv SESIOC_GETTEXT
|
|
Get the associated help text for an object (not yet implemented).
|
|
.B SES
|
|
devices often have descriptive text for an object which can tell
|
|
you things like location (e.g, "left power supply").
|
|
.It Dv SESIOC_INIT
|
|
Initialize the enclosure.

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

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