The VIP one or two times a day switches over to the other node and back.
FAilover works fine, but WHY it fails over?
Network ping times are superb good and i dont have an idea WHY the cluster algorithm thinks the other node should be better.
We have the exact same issue. Seems really odd to me that this would be normal behavior.
This isn't normal, there is a reason why the IVE is failing over. Many network checks are running at all times to ensure that the VIP owner is the most stable device in the cluster.
What do your event logs show at the time of the fail over?
has anyone found the solution to this problem? i am experiencing this scenario and my mgmt is worried about stability.
What SA version are you running?I remember we have a known issue in 7.1.r11 with VIP failing over which is fixed in 7.1r12.
Is "reason other node is better" the only message that appears in the event log? Normally, a cluster will split if the ARP ping between the two nodes fail more than 3 times. If this is the case, then the node sending the arp ping determines the other node is down. JTAC will need to review the event logs first and possibly require enabling debug logging on the SA to provide more details.
Is there a case already open for this issue?
