VM High Availability Reset

This event triggers in the event of system failure. HA VM Health Monitoring resets the virtual machine following a failure. It will also give a VM High Availability Error to inform Oracle VMware and SQL Server VMware database administrators of the failure.

Definition

When configured correctly, VMware High Availability (HA) can reduce or eliminate Oracle and SQL Server downtime due to system failure:

  • VMware HA responds to hardware failure by restarting the virtual machines on other hosts with available capacity in the cluster. An example of hardware failure is an isolation response, which generally occurs if a node of a VMware HA cluster is isolated from the network for 15 seconds or longer. VMware HA automatically monitors the availability of physical servers. VMware HA uses admission control to ensure that capacity is always available in order to restart all virtual machines affected by host failure.
  • VMware HA also protects against operating system failure by continuously monitoring a virtual machine's heartbeat and resetting it in when an operating system failure is detected.

VMware HA may be unable to power on virtual machines on alternate hosts or, in some cases, reset a virtual machine. When this occurs, AlarmVM will detect these situations and report on them.
