- If the node is made functional in an unstable environment, it will likely move into a suspended state again.
- Remove the preempt option from the nodes until the monitoring status is stable.
- This will help the healthy node retain the Active state, while the node encountering flaps will remain in the non-functional/passive state for investigation.
- It is advised have to "Passive link state" setting to "Auto". Refer to "What is the Difference between Auto and Shutdown mode for Passive Link?"
- After following the steps in KB How to Recover HA Pair Member from the Suspended State, the affected node moves into "Passive" state and eventually to the "Active" state due to preemption and its high priority.
