During installation, you configure the Data Director cluster with vSphere DRS and vSphere HA enabled, and with certain monitoring settings. You can later edit the Data Director cluster configuration to change the monitoring sensitivity for virtual machines.

As part of the installation process, you configure the Data Director cluster. See the vFabric Data Director Installation Guide. After installation, you can customize the cluster to work in your environment. See the vSphere Availability documentation and the vSphere Resource Management documentation for background information.

Not all changes that you can make to a vSphere cluster are compatible with Data Director. You must make sure that the cluster settings remain compatible with Data Director. Data Director checks the following settings.

DRS must be enabled. DRS automation level can be any of the supported options. Partially automated works best with Data Director in most situations.

Admission control must be enabled.

If cluster settings are not compatible with Data Director, and if you create a resource pool in the cluster, you cannot import the resource pool into a Data Director resource bundle.

If you change cluster settings from Data Director compatible to Data director incompatible, Data Director displays alerts but does not revert the settings. You must revert the settings to make the cluster compatible again.


Do not disable DRS because you lose all resource pools. Reenabling DRS does not resolve the issue. See Resource Bundles Become Unusable Because DRS Is Disabled.

If you customize the HA settings for a virtual machine, and if those settings are not compatible with Data Director, an alert appears. You are responsible to make the cluster compatible again.

Verify that you have log-in privileges and privileges for cluster modification for the vCenter Server system on which the Data Director cluster runs.


Log in to a vSphere Client that is connected to the vCenter Server on which the Data Director cluster runs.
