G.2.1 I want to change the netmask settings or the IP address in the host file without changing the GLS definitions for the cluster system.

Follow the procedure below to do the changes.

1. Stop RMS

   Execute the following command on any node.

   # hvshut -a

2. To make sure that the GLS service does not start, start the OS in single user mode.

3. Change the netmask by correcting /etc/inet/netmask or by using the ipadm(1m) command, and change the IP address in the /etc/inet/hosts file.

4. Restart the OS in multi-user mode.

5. Check that GLS is operating normally.

   Check that a GLS error message has not been output in the system log.

6. Check that the netmask and IP address changed in step 3. has been changed correctly.
