Prepare to Replace a Node

Gather the IP address settings of the failed node.
Unless stated otherwise, you will set the new node with the same IP address values as the unit being replaced:
- ICC Interface IP Address—For the ICC interface, you must assign a new IP address to the replacement node.
- Data Port Interface IP Address
- DNS Server Address
- NTP Server Address
Configure the VRRP priority for the replacement node.

Note
To ensure that the replacement node successfully joins the cluster, set the VRRP node priority of the replacement node to a value that is lower than the value of the existing nodes. This ensures that the VRRP address is pointing at a working node in the cluster during the joining process. After the replacement node has joined the cluster, you can set the VRRP node priority to first priority if desired, but this is not required.
Use the Basic Configuration Wizard to configure the replacement unit.
This is required if you are replacing the unit hardware. Node Replacement initially resets the node connections. It may not require new hardware.
For information about the Basic Configuration Wizard, see the appropriate Deployment Guide.
Upgrade the Appliance Software for the new node to the current firmware version.

After you have gathered the necessary information and verified the firmware version of all nodes in the cluster, you can run the Replace a Node procedure.
