Last published : Jun 11, 2026
Copy the I/O fencing files from an existing node to the new node and start I/O fencing on the new node. This task starts I/O fencing based on the fencing mechanism that is configured in the existing cluster.
To start I/O fencing on the new node
  1. Copy the following I/O fencing configuration files from one of the nodes in the existing cluster to the new node:
    • /etc/vxfenmode
    • /etc/vxfendg - This file is required only for disk-based fencing.
    • /etc/default/vxfen
  2. Start I/O fencing on the new node.
    \# /etc/init.d/vxfen.rc start
    1. Run the GAB configuration command on the new node to verify that the port b membership is formed.
    \# gabconfig -a
