In the GFS Shared File Systems, TCP service ports within the range of 9100 to 9163, and 9200 are reserved.
If these port numbers conflict with those for other applications, change the entry port number beginning with sfcfs- and sfcfsrm in the /etc/services file. If you need to change the port numbers, be aware that the port numbers beginning with sfcfs- and sfcfsrm must be the same on all the nodes.
