- Organization of this subsection
(1) Preparing the shared disk
A shared disk is required for sharing information when the system switches from the active node to the standby node. Before configuring the environment, you need to set up so that the shared disk can be accessed by both the active and standby nodes.
(2) Registering the host name and the IP address
If you do not use a DNS server, you must register the host names and IP addresses of the physical hosts and the logical host in the hosts file on both the primary node and the secondary node.
