Issue

  • When a remote cluster's interfaces become unavailable, errors, EMS, and changes in the cluster peer health output are reported.
  • For example, the output below indicates that some of the nodes in cluster1 are unreachable from cluster2

cluster2::> cluster peer health show
Node       Cluster-Name                 Node-Name
             Ping-Status               RDB-Health Cluster-Health Availability
---------- --------------------------- --------- --------------- -----------
  
node1
           cluster1                    node1
             Data: unreachable
             ICMP: unreachable         true      true            false
                                       node2
             Data: interface_reachable
             ICMP: interface_reachable true      true            true
node2
           cluster1                    node1
             Data: unreachable
             ICMP: unreachable         true      true            false
                                       node2
             Data: unreachable
             ICMP: unreachable         true      true            false
4 entries were displayed.

  • If you try to create a protection relationship from system manager (GUI), below warning is displayed while choosing the destination cluster:

Cluster peering status is unhealthy.

  • The cpeer.unavailable EMS message is also reported each time the remote cluster becomes unavailable

cluster2::> event log show -messagename cpeer.unavailable -instance
   
           Node: node1
      Sequence#: 71687
           Time: 5/15/2012 14:02:37 
 
       Severity: ALERT
         Source: mgwd
   Message Name: cpeer.unavailable
          Event: cpeer.unavailable: Peer cluster cluster1 is no longer available.

  • When it becomes available again, no EMS message will be reported.
    • Each time the remote cluster transitions from available to unavailable, a message will be received.
    • There is an implicit transition to available between each cpeer.unavailable message.
