Caution:
  • When rebooting the nodes of a cluster, reboot the other (slave) node first to avoid unnecessary takeovers.

  • When shutting down the nodes of a cluster, shut down the other (slave) node first. When powering on the nodes, start the master node first to avoid unnecessary takeovers.

  • When both nodes are running, avoid interrupting the connection between the nodes: do not unplug the Ethernet cables, reboot the switch or router between the nodes (if any), or disable the HA interface of SSB.
