Use the following procedures to change the network addresses of the Cell Manager or the Cell Members:

Change Cell Manager's Internal Address

On the cell manager

1. Change the cell manager’s internal address:

   1. For Appliance mode, find the correct interface name using the following command and run steps 1-4 on Change Appliance Network Address.

      ip a | grep '<Old Manager's Internal IP Address>' | awk '{print $7}'

   2. For Non-Appliance mode, please consult with your network admin and linux admin how to change the network interface address.

2. Update hosts file:

   sed -i "3,1000 s/<Old Manager's Internal IP Address>/<New Manager's Internal IP Address>/" /etc/hosts

3. Run the following SQL using “ij” utility (using CLI on DPOD’s server):

   update node set esip='<New Manager's Internal IP Address>' where esip='<Old Manager's Internal IP Address>';
   quit;

On each of cell members

1. Update hosts file:

   sed -i "3,1000 s/<Old Manager's Internal IP Address>/<New Manager's Internal IP Address>/" /etc/hosts

Restart the application on the cell manager and all the cell members

1. Stop all the application services using app-util.sh → option 2 (stop all)

2. Start all the application services using app-util.sh → option 3 (start all)
