Any special requirement to reboot node1 and node2 if Master for RDB's is all on node1?

Two HA's cluster, HA1: node1&node2; HA2: node3&node4

Any special requirement to reboot node1 and node2 (by failover/failback), if all RDB's masters are located on node1? for instance, Do I hve to move master's to node2 first before I could reboot node1, and then move master's back to node1 before reboot node2?

Hi,

No special requirements. In case of a reboot  the surviving node automatically becomes the RDB Master. Refer KB 3013879 What is Cluster HA and how is Epsilon utilized to maintain RDB Quorum?
