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.
