consadm(8) System Administration Commands consadm(8)
NAME
consadm - select or display devices used as auxiliary console devices
SYNOPSIS
/usr/sbin/consadm
/usr/sbin/consadm [-a device...] [-p]
/usr/sbin/consadm [-d device...] [-p]
/usr/sbin/consadm [-p]
DESCRIPTION
consadm selects the hardware device or devices to be used as auxiliary
console devices, or displays the current device. Only superusers are
allowed to make or display auxiliary console device selections.
Auxiliary console devices receive copies of console messages, and can
be used as the console during single user mode. In particular, they re‐
ceive kernel messages and messages directed to /dev/sysmsg. On Solaris
x86 based systems they can also be used for interaction with the boot‐
strap.
By default, selecting a display device to be used as an auxiliary con‐
sole device selects that device for the duration the system remains up.
If the administrator needs the selection to persist across reboots the
-p option can be specified.
consadm runs a daemon in the background, monitoring auxiliary console
devices. Any devices that are disconnected (hang up, lose carrier) are
removed from the auxiliary console device list, though not from the
persistent list. While auxiliary console devices may have been removed
from the device list receiving copies of console messages, those mes‐
sages will always continue to be displayed by the default console de‐
vice.
The daemon will not run if it finds there are not any auxiliary devices
configured to monitor. Likewise, after the last auxiliary console is
removed, the daemon will shut itself down. Therefore the daemon per‐
sists for only as long as auxiliary console devices remain active.
See eeprom(8) for instructions on assigning an auxiliary console device
as the system console.
OPTIONS
The following options are supported:
-a device Adds device to the list of auxiliary console devices.
Specify device as the path name to the device or devices
to be added to the auxiliary console device list.
-d device Removes device from the list of auxiliary console devices.
Specify device as the path name to the device or devices
to be removed from the auxiliary console device list.
-p Prints the list of auxiliary consoles that will be auxil‐
iary across reboots.
When invoked with the -a or -d options, tells the applica‐
tion to make the change persist across reboot.
EXAMPLES
Example 1 Adding to the list of devices that will receive console mes‐
sages
The following command adds /dev/term/a to the list of devices that will
receive console messages.
example# consadm -a /dev/term/a
Example 2 Removing from the list of devices that will receive console
messages
The following command removes /dev/term/a from the list of devices that
will receive console messages. This includes removal from the persis‐
tent list.
example# consadm -d -p /dev/term/a
Example 3 Printing the list of devices selected as auxiliary console
devices
The following command prints the name or names of the device or devices
currently selected as auxiliary console devices.
example# consadm

NOTES
Auxiliary console devices are not usable for kmdb or firmware I/O, do
not receive panic messages, and do not receive output directed to
/dev/console.
The consadm service is managed by the service management facility,
smf(7), under the service identifier:
svc:/system/consadm
Administrative actions on this service, such as enabling, disabling, or
requesting restart, can be performed using svcadm(8). The service's
status can be queried using the svcs(1) command.
