NAME

consadm - select or display devices used as auxiliary con- sole 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 mes- sages, and can be used as the console during single user mode. In particular, they receive kernel messages and mes- sages directed to /dev/sysmsg. On Solaris or IA based sys- tems they can also be used for interaction with the bootstrap. By default, selecting a display device to be used as an aux- iliary console 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 auxili- ary console devices. Any devices that are disconnected (hang up, lose carrier) are removed from the auxiliary con- sole 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 device. The daemon will not run if it finds there are not any auxi- liary devices configured to monitor. Likewise, after the last auxiliary console is removed, the daemon will shut itself down. Therefore the daemon persists for only as long as auxiliary console devices remain active.

OPTIONS

The following options are supported: -a device Adds device to the list of auxiliary console devices. SunOS 5.8 Last change: 15 Dec 1998 1 User Commands consadm(1m) Specify device as the path name to the device or dev- ices 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 auxiliary across reboots. When invoked with the -a or -d options , tells the application to make the change persist across reboot.

EXAMPLES

Example 1: Adding to the list of devices that will receive console messages The following command adds /dev/term/a to the list of dev- ices 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 persistent list. example# consadm -d -p /dev/term/a Example 3: Printing the list of devices selected as auxili- ary console devices The following command prints the name or names of the device or devices currently selected as auxiliary console devices. example# consadm
