3.11 Modifying the serialports File

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 on creating the /etc/serialports file. For more information on NIS and NIS+ maps, refer to the NIS/NIS+ System Administration Guide.

3.11.1 How to Modify the serialports File

1. As root, create a serialports file in the /etc directory.

2. 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

3.11.2 How to Create the serialports Table

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.
