Prepare to Replace a Node

Before you can replace a node in a cluster, consider the following. For detailed information about appliance installation and cluster configuration, refer to the following guides:

Note

This task does not apply to stand-alone deployments.

Take the following steps:

Gather the IP address settings of the failed node.
The following settings must match the values of the unit being replaced:
- ICC Interface IP Address
- 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 controller 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 Node Replacement procedure.
