You can use Live Partition Mobility to perform a stateful migration of an LPAR in a VCS environment. During this period, you may see notifications if the migrating node is unable to heartbeat with its peers within LLT's default peer inactive timeout. To avoid false failovers, determine how long the migrating node is unresponsive in your environment. If that time is less than the default LLT peer inactive timeout, VCS operates normally. If not, increase the peer inactive timeout to an appropriate value on all the nodes in the cluster before beginning the migration. Reset the value back to the default after the migration is complete.
