Procedure: Changing the service IP address of a node canister

This procedure identifies many methods that you can use to change the service IP address of a node canister.

When you change an IPv4 address, you change the IP address, the subnet, mask, and gateway. When you change an IPv6 address, you change the IP address, prefix, and gateway.

Which method to use depends on the status of the system and the other node canisters in the system. Follow the methods in the order shown until you are successful in setting the IP address to the required value.

You can set an IPv4 address, an IPv6 address, or both, as the service address of a node. Enter the required address correctly. If you set the address to 0.0.0.0 or 0000:0000:0000:0000:0000:0000:0000, you disable the access to the port on that protocol.

Change the service IP address.

Use the control enclosure management GUI when the system is operating and the system is able to connect to the node with the service IP address that you want to change.
1. Select Settings > Network from the navigation.
2. Select Service IP Addresses.
3. Complete the panel. Be sure to select the correct node to configure.
Use the service assistant when you can connect to the service assistant on either the node canister that you want to configure or on a node canister that can connect to the node canister that you want to configure:
1. Make the node canister that you want to configure the current node.
2. Select Change Service IP from the menu.
3. Complete the panel.
Use one of the following procedures if you cannot connect to the node canister from another node:
- Use the initialization tool to write the correct command file to the USB flash drive.
- Use a text editor to create the command file on the USB flash drive.
