This VMware alarm shows that a secondary VM in a VMware Fault Tolerance group timed out while attempting to start.
VMware Fault Tolerance is a feature that provides guest redundancy for most mission-critical applications that cannot tolerate any interruption of service or data loss. It can be enabled onOracle VMware or SQL Server VMwarevirtual environments that reside in an HA cluster.
When VMware Fault Tolerance is enabled on a primary VM, a secondary VM is created on a different host in the cluster. The secondary VM runs in virtual lockstep with the primary VM. The following events are triggered when a failure occurs:
- A transparent failover takes place in which the secondary VM continues execution from the exact point where the primary left off.
- The secondary VM becomes the new primary VM.
- A new secondary virtual machine is started on another host.
During this failover, there is no data loss or noticeable service interruption.
Note: VMware Fault tolerance can only be enabled on VMs that meet specified Fault Tolerance requirements.
