38.Dt SES 4
39.Os
40.Sh NAME
41.Nm ses
42.Nd SCSI Environmental Services Driver
43.Sh SYNOPSIS
44.Cd ses* at scsibus? target ? lun ?
45.Sh DESCRIPTION
46The
47.Nm ses
48driver provides support for all
49.Tn SCSI
50devices of the environmental services class that are attached to the system
51through a supported
52.Tn SCSI
53Host Adapter, as well as emulated support for SAF-TE (SCSI Accessible
54Fault Tolerant Enclosures).
55The environmental services class generally are enclosure devices that
56provide environmental information such as number of power supplies (and
57state), temperature, device slots, and so on.
58.Pp
59A
60.Tn SCSI
61Host
62adapter must also be separately configured into the system
63before a
64.Tn SCSI
65Environmental Services device can be configured.
66.Sh IOCTLS
67The following
68.Xr ioctl 2
69calls apply to
70.B SES
71devices.
72They are defined in the header file
73.Aq Pa scsi/ses.h
74(q.v.).
75.Pp
76.Bl -tag -width SESIOC_GETENCSTAT
77.It Dv SESIOC_GETNOBJ
78Used to find out how many
79.B SES
80objects are driven by this particular device instance.
81.It Dv SESIOC_GETOBJMAP
82Read, from the kernel, an array of SES objects which contains
83the object identifier, which sub-enclosure it is in, and the
84.B SES
85type of the object.
86.It Dv SESIOC_GETENCSTAT
87Get the overall enclosure status.
88.It Dv SESIOC_SETENCSTAT
89Set the overall enclosure status.
90.It Dv SESIOC_GETOBJSTAT
91Get the status of a particular object.
92.It Dv SESIOC_SETOBJSTAT
93Set the status of a particular object.
94.It Dv SESIOC_GETTEXT
95Get the associated help text for an object (not yet implemented).
96.B SES
97devices often have descriptive text for an object which can tell
98you things like location (e.g, "left power supply").
99.It Dv SESIOC_INIT
100Initialize the enclosure.

110.Sh DIAGNOSTICS
111When the kernel is configured with
112.Tn DEBUG
113enabled, the first open to an SES device will spit out overall enclosure
114parameters to the console.

120.Sh HISTORY
121The
122.Nm
123driver was written for the
124.Tn SCSI
125subsystem by Matthew Jacob. This is the functional equivalent of a similar
126driver available in Solaris, Release 7.
