If I have a situation where I am backing up a server by failing over to a backup standby inactive server that is performing no other function other than testing the pluse beat of the primary server. If someone causes the primary server to be rebooted is there any chance that the backup server will sense the primary gone and take over assuming it failed. What kind of failure needs to take place befor the backup replaces the primary/ Jim4522

Thanks. We'll let you know when a new response is added.

In a clustered environment the application will failover to the passive node if the active node is rebooted.

Best practice would be to manually failover the application before the reboot.

You could allow the application to failback once the original active has come back but I would recommend doing that under manual control

    RichS, is the failback always triggered manually, or can the original passive server (which presumable is now the active) sense when the original active server has come back. Jim4522

    The failback is triggered manually. It does not automatically go back to the original active node, no. The Node will stay active wherever it failed to unless that active node reboots for some reason or the cluster is manually failed back.

    Technochic, thanks for the info. Just to be sure will a reboot of an active node automatical cause a failover to a passive node, regadless of the reason for the reboot?
