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.
n
DRS must be enabled. DRS automation level can be any of the supported options. Partially automated
works best with Data Director in most situations.
n
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.
CAUTION 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,” on page 116.
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.
