Configuring I/O fencing on the new node

Last published : Sep 11, 2026
If the existing cluster is configured for I/O fencing, perform the following tasks on the new node:
  • Prepare to configure I/O fencing on the new node.
See Preparing to configure I/O fencing on the new node.
  • If the existing cluster runs server-based fencing, configure server-based fencing on the new node.
See Configuring server-based fencing on the new node.
If the existing cluster runs disk-based fencing, you need not perform any additional step. Skip to the next task. After you copy the I/O fencing files and start I/O fencing, disk-based fencing automatically comes up.
  • Copy the I/O fencing files from an existing node to the new node and start I/O fencing on the new node.
See Starting I/O fencing on the new node.
If the existing cluster is not configured for I/O fencing, perform the procedure to add the new node to the existing cluster.
See Adding the node to the existing cluster.
