Failover Warnings

Failover issues warnings when certain tasks cannot be performed.

Failover Appliance Unavailable

When the failover membership cannot be formed, following message is displayed. The warning message describes the nature of the failover issue.

Failover in Degraded Mode

When the failover appliances appear to get out of sync, a message is displayed.

In this situation, a permanent failure of one of the appliances can result in data loss. If both nodes are mostly in sync, this resynchronization operation is relatively fast. However, if the data size difference is large, the operation time depends mainly on the network, CPU, and I/O bandwidth available. There are multiple phases involved in resynchronizing the failover, each with their own status and percentage to completion.
