NAME
luxadm - administration program for the Sun Enterprise Net-
work Array (SENA), RSM, SPARCstorage Array (SSA) subsystems,
and individual Fiber Channel Arbitrated Loop (FC_AL) devices
SYNOPSIS
luxadm [ options ... ] subcommand [ options ... ] enclo-
sure [ ,dev ] | pathname ...
DESCRIPTION
The luxadm program is an administrative command that manages
the SENA, RSM, SPARCstorage Array subsystems and individual
FC_AL devices. luxadm performs a variety of control and
query tasks depending on the command line arguments and
options used.
The command line must contain a subcommand. The command line
may also contain options, usually at least one enclosure
name or pathname, and other parameters depending on the sub-
command. You need specify only as many characters as are
required to uniquely identify a subcommand.
Specify the device that a subcommand interacts with by
entering a pathname. For the SENA subsystem, a disk device
or enclosure services controller may instead be specified by
entering the World Wide Name (WWN) for the device or a port
to the device. The device may also be specified by entering
the name of the SENA enclosure, and an optional identifier
for the particular device in the enclosure. The individual
FC_AL devices may be specified by entering the WWN for the
device or a port to the device.
Pathname
Specify the device or controller by either a complete physi-
cal pathname or a complete logical pathname.
For SENA, a typical physical pathname for a device is:
/devices/sbus@1f,0/SUNW,socal@1,0/sf@0,0/ssd@w2200002037000f96,
0:a,raw
or
/devices/io-unit@f,e0200000/sbi@0,0/SUNW,socal@2,0/sf@0,0/ssd@34,
0:a,raw
For all SENA IBs (Interface Boards) on the system, a logical
link to the physical paths is kept in the directory /dev/es.
SunOS 5.8 Last change: 29 Jul 1999 1
Maintenance Commands luxadm(1M)
An example of a logical link is /dev/es/ses0.
The WWN may be used in place of the pathname to select an
FC_AL device or SENA subsystem IB. The WWN is a unique 16
hexadecimal digit value that specifies either the port used
to access the device or the device itself. A typical WWN
value is:
2200002037000f96
See NOTES for more information on the WWN formats.
For the SPARCstorage Array controller, a typical physical
pathname is:
/devices/.../.../SUNW,soc@3,0/SUNW,pln@
axxxxxxx,xxxxxxxx:ctlr
whereas, a typical physical pathname for an RSM controller
is:
/devices/sbus@1f,0/QLGC,isp@1,10000:devctl
In order to make it easier to address the SPARCstorage Array
or RSM controller, a logical pathname of the form cN is sup-
ported, where N is the logical controller number. luxadm
uses the cN name to find an entry in the /dev/rdsk directory
of a disk that is attached to the SPARCstorage Array or RSM
controller. The /dev/rdsk entry is then used to determine
the physical name of the SPARCstorage Array or RSM con-
troller.
For a SPARCstorage Array disk, a typical physical pathname
is:
/devices/.../.../SUNW,soc@3,0/SUNW,
pln@axxxxxxx,xxxxxxxx/ssd@0,0:c,raw
and a typical logical pathname is:
/dev/rdsk/c1t0d0s2
SunOS 5.8 Last change: 29 Jul 1999 2
Maintenance Commands luxadm(1M)
For an RSM a typical physical pathname is:
/devices/sbus@1f,0/QLGC,isp@1,10000/sd@8,0:c,raw
and a typical logical pathname is:
/dev/rdsk/c2t8d0s2
For individual FC_AL devices, a typical physical pathname
is:
/devices/sbus@3.0/SUNW,socal@d,10000/sf@0,0/ssd@w2200002037049fc3,0:a,raw
and a typical logical pathname is:
/dev/rdsk/c1t0d0s2
Enclosure
For SENA, a device may be identified by its enclosure name
and slotname:
box_name[,fslot_number]
box_name[,rslot_number]
box_name is the name of the SENA enclosure, as specified by
the enclosure_name subcommand. When used without the
optional slot_number parameter, the box_name identifies the
SENA subsystem IB.
f or r specifies the front or rear slots in the SENA enclo-
sure.
slot_number specifies the slot number of the device in the
SENA enclosure, 0-6 or 0-10.
See disks(1M) and devlinks(1M) for additional information on
logical names for disks and subsystems.
OPTIONS
The following options are supported by all subcommands:
-e Expert mode. This option is not recommended for the
novice user.

described with the subcommand in the USAGE section.
OPERANDS
The following operands are supported:
enclosure
The box_name of the SENA.
pathname
The logical or physical path of a SENA IB,
SPARCstorage Array or RSM controller (cN name) or disk
device. pathname can also be the WWN of a SENA IB,
SENA disk, or individual FC_AL device.
USAGE
Subcommands
display enclosure[,dev]...| pathname...
display -p pathname...
display -r enclosure[,dev]...| pathname...
display -v enclosure[,dev]...| pathname...
Displays enclosure or device specific data.
Subsystem data consists of enclosure environmental
sense information and status for all subsystem dev-
ices, including disks.
Disk data consists of inquiry, capacity, and confi-
guration information.
-p Displays performance information for the device
or subsystem specified by pathname. This option
only applies to subsystems that accumulate per-
formance information.
-r Displays error information for the FC_AL device
specified by the pathname, or, if the path is a
SENA, for all devices on the loop. The -r option
only applies to SENA subsystems and individual
FC_AL devices.
-v Displays in verbose mode, including mode sense
data.
download [ -s ] [ -w WWN ] [ -f filename_path ] enclosure...
Download the prom image pointed to by filename_path to

Maintenance Commands luxadm(1M)
the SENA subsystem Interface Board unit or the
SPARCstorage Array controllers specified by the enclo-
sure or pathname. The SPARCstorage Array must be reset
in order to use the downloaded code.
When the SENA's download is complete, the SENA will be
reset and the downloaded code executed. If no filename
is specified, the default prom image will be used. The
default prom image for the SPARCstorage Array con-
troller is in usr/lib/firmware/ssa/ssafirmware. The
default prom image for the SENA is in the directory
usr/lib/locale/C/LC_MESSAGES and is named ibfirmware.
-s Save. The -s option is used to save the down-
loaded firmware in the FEPROM. If -s is not
specified, the downloaded firmware will not be
saved across power cycles. The -s option does
not apply to the SPARCstorage Array controller
as it always writes the downloaded firmware into
the FEPROM. When using the -s option, the down-
load subcommand modifies the FEPROM on the sub-
system and should be used with caution.
-w WWN
Change the SPARCstorage Array controller's World
Wide Name. WWN is a 12-digit hex number; leading
zeros are required. The -w option applies only
to the SPARCstorage Array. The new SPARCstorage
Array controller's image will have the least
significant 6 bytes of the 8-byte World Wide
Name modified to WWN.
enclosure_name new_name enclosure | pathname
Change the enclosure name of the enclosure or enclo-
sures specified by the enclosure or pathname. The new
name (new_name) must be 16 or less characters. Only
alphabetic or numeric characters are acceptable. This
subcommand applies only to the SENA.
fc_s_download [ -F ] [ -f fcode-file ]
Download the fcode contained in the file fcode-file
into all the FC/S Sbus Cards. This command is interac-
tive and expects user confirmation before downloading
the fcode.
Use fc_s_download only in single-user mode. Using
fc_s_download to update a host adapter while there is
I/O activity through that adapter will cause the
adapter to reset. Newly updated FCode will not be exe-
cuted or visible until a system reboot.
SunOS 5.8 Last change: 29 Jul 1999 5
Maintenance Commands luxadm(1M)
-f fcode-file
When invoked without the -f fcode-file option,
the current version of the fcode in each FC/S
Sbus card is printed.
-F Forcibly downloads the fcode, but the command
still expects user confirmation before the down-
load. The version of the FC/S Sbus Cards fcode
that was released with this version of the
Operating System is kept in the directory
usr/lib/firmware/fc_s and is named fc_s_fcode.
fcal_s_download [ -f fcode-file ]
Download the fcode contained in the file fcode-file
into all the FC100/S Sbus Cards. This command is
interactive and expects user confirmation before down-
loading the fcode.
Use fcal_s_download only in single-user mode. Using
fcal_s_download to update a host adapter while there
is I/O activity through that adapter will cause the
adapter to reset. Newly updated FCode will not be exe-
cuted or visible until a system reboot.
-f fcode-file
When invoked without the -f option, the current
version of the fcode in each FC100/S Sbus card
is printed. The version of the FC100/S Sbus
Cards fcode that was released with this version
of the operating system is kept in the directory
usr/lib/firmware/fc_s and is named fcal_s_fcode.
fcode_download [-p] [-d dir-name]
Locate the installed FC/S, FC100/S, FC100/P, or
FC100/2P host bus adapter cards and download the FCode
files in dir-name to the appropriate cards. The com-
mand determines the correct card for each type of
file, and is interactive. User confirmation is
required before downloading the FCode to each device.
Use fcode_download to load FCode only in single-user
mode. Using fcode_download to update a host adapter
while there is I/O activity through that adapter
causes the adapter to reset. Newly updated FCode will
not be executed or visible until a system reboot.
-d dir-name
Download the FCode files contained in the direc-
tory dir-name to the appropriate adapter cards.
When invoked without the -d option, the default

Maintenance Commands luxadm(1M)
directory usr/lib/firmware/fc_s is used.
-p Prints the current version of FCode loaded on
each card. No download is performed.
inquiry enclosure[,dev ]... | pathname...
Display the inquiry information for the selected dev-
ice specified by the enclosure or pathname.
insert_device [ enclosure,dev... ]
Assist the user in the hot insertion of a new device
or a chain of new devices. Refer to NOTES for limita-
tions on hotplug operations. This subcommand applies
only to the SENA, RSM, and individual FC_AL drives.
For the SENA, if more than one enclosure has been
specified, concurrent hot insertions on multiple
busses can be performed. With no arguments to the sub-
command, entire enclosures or individual FC_AL drives
can be inserted. For the RSM, only one controller can
be specified. For the SENA, this subcommand guides the
user interactively through the hot insertion steps of
a new device or chain of devices. If a list of disks
was entered it will ask the user to verify the list of
devices to be inserted is correct, at which point the
user can continue or quit. It then interactively asks
the user to insert the disk(s) or enclosure(s) and
then creates and displays the logical pathnames for
the devices.
For the RSM, the following steps are taken:
o Quiesce the bus or buses which support
quiescing and unquiescing.
o Inform the user that the device can be
safely inserted .
o Request confirmation from the user that the
device has been inserted.
o Unquiesce the bus or buses which support
quiescing and unquiescing.
o Create the logical device name for the new
device.
led enclosure,dev...| pathname...
Display the current state of the LED associated with
the disk specified by the enclosure or pathname. This
subcommand only applies to subsystems that support
this functionality.
SunOS 5.8 Last change: 29 Jul 1999 7
Maintenance Commands luxadm(1M)
led_blink enclosure,dev...| pathname...
Requests the subsystem to start blinking the LED asso-
ciated with the disk specified by the enclosure or
pathname. This subcommand only applies to subsystems
that support this functionality.
led_off enclosure,dev...| pathname...
Requests the subsystem to disable (turn off) the LED
associated with the disk specified by the enclosure or
pathname. On a SENA subsystem, this may or may not
cause the LED to turn off or stop blinking depending
on the state of the SENA subsystem. Refer to the SENA
Array Installation and Service Manual (p/n 802-7573).
This subcommand only applies to subsystems that sup-
port this functionality.
led_on pathname...
Requests the subsystem to enable (turn on) the LED
associated with the disk specified by the pathname.
This subcommand only applies to subsystems that sup-
port this functionality.
power_off [ -F ] enclosure[,dev]... | pathname ...
number
power_off pathname [ enclosure-
port ] ... | controller tray-
When a SENA is addressed, this subcommand causes the
SENA subsystem to go into the power-save mode. The
SENA drives are not available when in the power-save
mode. When an Enclosure Services card within the
SPARCstorage Array is addressed, the RSM tray is
powered down. When a drive in a SENA is addressed the
drive is set to the drive off/unmated state. In the
drive off/unmated state, the drive is spun
down (stopped) and in bypass mode.
-F The force option only applies to the SENA.
Instructs luxadm to attempt to power off one or
more devices even if those devices are being
used by this host (and are, therefore, busy).
Warning: Powering off a device which has data
that is currently being used will cause
unpredictable results. Users should attempt to
power off the device normally (without -F)
first, only resorting to this option when sure
of the consequences of overriding normal checks.
power_on enclosure[,dev]..
Causes the SENA subsystem to go out of the power-save

mode, when this subcommand is addressed to a SENA.
There is no programmatic way to power on the
SPARCstorage Array RSM tray. When this subcommand is
addressed to a drive the drive is set to its normal
start-up state.
probe [ -p ]
Finds and displays information about all attached SENA
subsystems and individual FC_AL devices, including the
logical pathname, the WWNs, and enclosure names. This
subcommand warns the user if it finds different SENAs
with the same enclosure names.
-p Includes the physical pathname in the display.
qlgc_s_download [ -f fcode-file ]
Download the FCode contained in the file fcode-file
into all the FC100/P, FC100/2P PCI host adapter cards.
This command is interactive and expects user confirma-
tion before downloading the FCode to each device. Only
use qlgc_s_download in single-user mode. Using
qlgc_s_download to update a host adapter while there
is I/O activity through that adapter will cause the
adapter to reset. Newly updated FCode will not be exe-
cuted or visible until a system reboot.
-f fcode-file
When invoked without the -f option, the current
version of the FCode in each FC100/P, FC100/2P
PCI card is printed.
release pathname
Release a reservation held on the specified disk. The
pathname should be the physical or logical pathname
for the disk. If the pathname is of the SPARCstorage
Array controller, then all of the disks in the
SPARCstorage Array will be released.
This subcommand is included for historical and diag-
nostic purposes only.
remove_device [ -F ] enclosure[,dev]...| pathname...
Assists the user in hot removing a device or a chain
of devices. This subcommand can also be used to remove
entire enclosures. This subcommand applies to the
SENA, RSM, and individual FC_AL drives. Refer to NOTES
for limitations on hotplug operations. For the SENA
and individual FC_AL devices, this subcommand guides
the user through the hot removal of a device or dev-
ices. During execution it will ask the user to verify
SunOS 5.8 Last change: 29 Jul 1999 9
Maintenance Commands luxadm(1M)
the list of devices to be removed is correct, at which
point the user can continue or quit. It then prepares
the disk(s) or enclosure(s) for removal and interac-
tively asks the user to remove the disk(s) or
enclosure(s).
For the RSM, the steps taken are:
o Take the device offline.
o Quiesce the bus or buses which support quiescing
and unquiescing.
o Inform user that the device can be safely
removed.
o Request confirmation from the user that the dev-
ice has been removed.
o Unquiesce the bus or buses which support quiesc-
ing and unquiescing.
o Bring the (now removed) device back online.
o Remove the logical device name for the removed
device.
-F Instructs luxadm to attempt to hot plug one or
more devices even if those devices are being
used by this host (and are, therefore, busy or
reserved), to force the hotplugging operation.
Warning: Removal of a device which has data that
is currently being used will cause unpredictable
results. Users should attempt to hotplug nor-
mally (without -F) first, only resorting to this
option when sure of the consequences of overrid-
ing normal hotplugging checks.
replace_device [ -F ] pathname
This subcommand applies only to the RSM. Refer to
NOTES for limitations on hotplug operations. This sub-
command guides the user interactively through the hot
replacement of a device.
For the RSM, the steps taken are:
o Take the device offline.

o Request confirmation from the user that the dev-
ice has been replaced.
o Unquiesce the bus or buses which support quiesc-
ing and unquiescing.
o Bring the device back online.
-F Instructs luxadm to attempt to hot plug one or
more devices even if those devices are busy or
reserved, (that is, to force the hotplugging
operation).
Warning: Removal of a device which has data that
is currently being used will cause unpredictable
results. Users should attempt to hotplug nor-
mally (without -F) first, only resorting to this
option when sure of the consequences of overrid-
ing normal hotplugging checks.
reserve pathname
Reserve the specified disk for exclusive use by the
issuing host. The pathname used should be the physical
or logical pathname for the disk. If the pathname is
of the SPARCstorage Array controller, then all of the
disks in the SPARCstorage Array will be reserved.
This subcommand is included for historical and diag-
nostic purposes only.
set_boot_dev [ -y ] pathname
Set the boot-device variable in the system PROM to the
physical device name specified by pathname, which can
be a block special device or the pathname of the
directory on which the boot file system is mounted.
The command normally runs interactively requesting
confirmation for setting the default boot-device in
the PROM. The -y option can be used to run it non-
interactively, in which case no confirmation is
requested or required.
start [ -t tray-number ] pathname...
Spin up the specified disk(s). If pathname specifies

NOTES
See the SENA Array Installation and Service Manual for addi-
tional information on the SENA. Refer to Tutorial for SCSI
use of IEEE Company_ID, R. Snively, for additional informa-
tion regarding the IEEE extended WWN. See SEE ALSO.
Currently, only some device drivers support hot plugging. If
hot plugging is attempted on a disk or bus where it is not
supported, an error message of the form:
luxadm: can't acquire "PATHNAME": No such file or directory
will be displayed.
You must be careful not to quiesce a bus that contains the
root or the /usr filesystems or any swap data. If you do
quiesce such a bus a deadlock can result, requiring a system
reboot.
