The TCP port number on which the xfs server daemon listens is normally the “fs” port, typically defined as 7100 in the /etc/services file. However, the -port option that the cluster administrator includes with the xfs command enables the cluster administrator to override the default setting.
You can use the Port_list property in the SUNW.xfnts resource type to set the default value and to enable the cluster administrator to use the -port option with the xfs command. You define the default value of this property as 7100/tcp in the RTR file. In the SUNW.xfnts Start method, you pass Port_list to the -port option on the xfs command line. Consequently, a user of this resource type is not required to specify a port number (the port defaults to 7100/tcp). The cluster administrator can specify a different value for the Port_list property when the cluster administrator configures the resource type.
