This was not for 220s specifically.

This can be accomplished in many ways. Some of the recommended methods
are discussed below.

1.The file /etc/default/kbd can set a variable called KEYBOARD_ABORT.
Uncomment the line containing this variable in this file as shown below:

KEYBOARD_ABORT=disable

Then run the command "kbd -i" or simply reboot the system.The "kbd -i"
command will force the system to reread the /etc/default/kbd file.

This will permanently disable all the STOP+A and serial device break
signals on the system.

You can re-enable the break sequence by commenting out this line in the
/etc/default/kbd file and rebooting the system or running the "kbd -i"
command again.

2. You can enable/disable breaks with out changing any file entries
from the command line as well.

The " kbd -a enable" will enable the system to start accepting the
break signal and the "kbd -a disable" will disable the system from
accepting the break signal. These changes will be temporary and
be in effect only till the system reboots.

3. You can also reboot the system after setting the following variable
in /etc/system file as shown:

set abort_enable=0

This will disable all break signals on the system.

Solaris 8 introduced a new feature which gives the system the
ability to force a hanging system to halt when required, without
allowing random or spurious Breaks to cause an unintentional stop. The
new sequence to stop the system is <RETURN> <TILDE> <CONTROL B>.There
must be an interval of more than 0.5 seconds between characters, and
the entire string must be entered in less than 5 seconds. This is true
only with serial devices acting as consoles and not for systems with
keyboards of their own.

This feature has been backported to Solaris 2.6 and Solaris 7 as well. The
patch 105924-10 for Solaris 2.6 and 107589-02 or higher for Solaris 7 is
required to enable this feature.

To enable the alternate boot sequence, just type "kbd -a alternate" or
if this change needs to be permanent, reboot the system after
uncommenting the following line in the /etc/default/kbd file :

KEYBOARD_ABORT=alternate

Note: a) Do not uncomment the KEYBOARD_ABORT=disable line while doing this.
b) Do not set abort_enable=0 in /etc/system while doing this.

NAME

       scconf_transp_adap_qfe - configure the qfe transport adapter

DESCRIPTION

       Note -

	 Beginning  with  the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software
	 still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more  infor-
	 mation about the object-oriented command set, see the Intro(1CL) man page.

       You can configure qfe Ethernet adapters as cluster transport adapters. These adapters can only be used with transport type dlpi.

       The  qfe Ethernet adapter connects to a transport switch or to another Ethernet adapter on a different node. In either case, the connection
       is made through a transport cable.

       When a transport switch is used and the endpoints of the transport cable are configured by using scconf, scinstall, or other tools, you are
       asked to specify a port name on the transport switch.  You can provide any port name, or accept the default,  as long as the name is unique
       for the switch.

       The default is to set the port name to the node ID hosting  the adapter at the other end of the cable.

       There are no user configurable properties for cluster transport adapters of this type.
