Use this procedure if you need to configure or change OpenBoot PROM settings.
Connect to the terminal concentrator port.
# telnet tc_name tc_port_number |
Specifies the name of the terminal concentrator.
Specifies the port number on the terminal concentrator. Port numbers are configuration dependent. Typically, ports 2 and 3 (5002 and 5003) are used for the first cluster installed at a site.
Shut down the cluster node gracefully by using the scswitch(1M) command to evacuate any resource or disk device groups and then shutdown(1M) to bring the node to the OBP prompt.
# scswitch -S -h node[,...] # shutdown -g0 -y -i0 |
Do not use send brk on a cluster console to shut down a cluster node. If you use send brk and then type go at the OBP prompt to reboot, the node will panic. This functionality is not supported within a cluster.
Execute the OBP commands.
