The serialports file maps a host name to the Terminal Concentrator and Terminal Concentrator serial port to which the console of the host is connected. This file can be created as an NIS or NIS+ map or locally in the /etc directory.
The serialports file requires updating only if:
The host name(s) changes
The Terminal Concentrator name changes
The port number of the host on the Terminal Concentrator changes
Additional hosts are being added to this Terminal Concentrator
More cluster nodes are added
Refer to the Sun Cluster 2.2 Software Installation Guide for information about creating the /etc/serialports file. For more information about NIS and NIS+ maps, refer to the NIS/NIS+ System Administration Guide.
As root, create a serialports file in the /etc directory.
For a Sun Enterprise(TM) 10000 system, enter hostname sspname 23 in the serialports file. For all other hardware systems, enter hostname terminal_concentrator serial_port in the serialports file.
For Sun Enterprise 10000:
# Sun Enterprise Cluster nodes phys-hahost1 sspname 23 phys-hahost2 sspname 23 phys-hahost3 sspname 23 phys-hahost4 sspname 23 |
For all other hardware systems:
# Sun Enterprise Cluster nodes phys-hahost1 hacluster-tc 5002 phys-hahost2 hacluster-tc 5003 phys-hahost3 hacluster-tc 5004 phys-hahost4 hacluster-tc 5005 |
In an NIS+ environment, you need to create a serialports table. The entries in this table are the same as the entries in the /etc/serialports file.
To create a serialports table in a domain named mydomain in an NIS+ environment, use the following command:
# nistbladm -c key-value key=SI value=clusters.mydomain. |
The trailing period (.) at the end of the nistbladm command is required.
