NETGEAR 8800 Chassis Switch CLI Manual Table 6. Node States Node State BACKUP DOWN FAIL INIT MASTER STANDBY Description In the backup state, this node becomes the primary node if the primary fails or enters the DOWN state. The backup node also receives the checkpoint state data from the primary. In the down state, the node is not available to participate in leader election. The node enters this state during any user action, other than a failure, that makes the node unavailable for management. Examples of user actions are: • Upgrading the software • Rebooting the system using the reboot command • Initiating an MSM/MM failover using the run msm-failover command • Synchronizing the MSM's/MM's software and configuration in non-volatile storage using the synchronize command In the fail state, the node has failed and needs to be restarted or repaired. The node reaches this state if the system has a hardware or software failure. In the initial state, the node is being initialized. A node stays in this state when it is coming up and remains in this state until it has been fully initialized. Being fully initialized means that all of the hardware has been initialized correctly and there are no diagnostic faults. In the primary state, the node is responsible for all switch management functions. In the standby state, leader election occurs-the primary and backup nodes are elected. The priority of the node is only significant in the standby state. Example The following command displays the status of the node, the priority of the node, and the general health of the system: show node The following is sample output from this command: Node State Priority SwHealth HwHealth MSM-A MASTER 0 49 7 MSM-B BACKUP 0 49 7 If you specify the detail option, the same information is displayed on a per node basis rather than in a tabular format. Node MSM-A information: Node State: MASTER Node Priority: 0 Sw Health: 49 Hw Health: 7 Node MSM-B information: Node State: BACKUP Node Priority: 0 Chapter 3. Commands for Managing the Switch | 117
