VMware Adaptor

The adaptor for the VMware environment provides a set of availability checks and rule actions for the vSphere environment. These checks and rule actions the adaptor must be configured with a valid vCenter Administrator username and password, and the connection details to vCenter (Please refer to the Reference Guide for details).

  1. Fault Tolerance (FT) Availability Check  - enabled by default
  2. High Availability (HA) Check  - enabled by default
  3. vCenter Availability Check - enabled by default
  4. Service Protection
    • VMTools
  5. Rule Actions are available to application plug-ins installed with vAppHA. When the rule action triggers, the event is logged in vCenter.
    • VMRestart
    • VMotion to the target configured in the VMAdaptor
    • VMotion and Restart Application
  6. Standard service and rule actions available and applicable to vAppHA protected applications:
    • Recover Service
    • Restart Applications
    • Log Warning
  7. For health checks and rule actions to complete successfully the VMAdaptor must be configured with Username, Password, and vCenter details.
    • Warnings and Errors will be logged if these are not configured
    • If vCenter and the vAppHA VM are not on the same subnet these checks and rule actions will fail and must be disabled

VMotion Targets

  1. Provide a destination target host. This is the ESX host name, exactly as it appears in vCenter, or the IP address.
  2. Provide the name of the Resource Pool you wish to VMotion to:
    • This Resource Pool should not contain the current ESX host; DRS selects a host with the named Resource Pool
    • If the Resource Pool contains the host on which vAppHA VM is currently running, DRS recommends the current ESX host and VMotion will not take place.
