NAME

ses - SCSI enclosure services device driver

SYNOPSIS

ses@target,lun

DESCRIPTION

The ses device driver is an interface to SCSI enclosure services
devices. These devices sense and monitor the physical conditions in an
enclosure as well as allow access to the status reporting and
configuration features of the enclosure (such as indicator LEDs on the
enclosure.)

ioctl(9E) calls may be issued to ses to determine the state of the
enclosure and to set parameters on the enclosure services device.

No ses driver properties are defined. Use the ses.conf file to configure
the ses driver.

IOCTLS

The SES driver currently supports the SES, SAFTE and SEN enclosure
service chipsets. SEN and SAFTE protocols are translated internally in
the driver into SES compliant data structures. This enables the SES
driver to work seamlessly with different protocols and eliminates the
need to enhance user applications.

SESIOC_GETNOBJ
Returns an unsigned integer that represents the
number of SES data structures in the enclosure
services chip.

SESIOC_GETOBJMAP
Returns a size array containing ses_object elements
communicated through SESIOC_GETNOBJ(). ses_object is
defined in sesio.h.

SESIOC_INIT
Instructs the device to perform a self-diagnostic
test. Currently SES & SEN devices always return
success.

SESIOC_GETENCSTAT
Returns an unsigned character that represents status
enclosure as defined by Table 25 in Section 7.1.2 of
the SES specification NCITS 305-199x.

SESIOC_GETOBJSTAT
This ioctl is passed an ses_objarg containing the
obj_id you want to set, then fills in the remaining
fields according to element status page of the SES
specification.

SESIOC_SETOBJSTAT
Sets options in the control field. You set control
field options by filling out all fields in
ses_objarg. Field definitions are presented in
Section 7.2.2 of the SES specification.
