Perform Advanced Cluster Configuration
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.
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
HA, host monitoring, and admission control must be enabled.
n
VM Monitoring is set to VM and Application Monitoring.
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 to 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 restore the resource
pools. See “Resource Bundles Become Unusable Because DRS Is Disabled,” on page 188.
If you customize the HA settings for a virtual machine, and if those settings are not compatible with Data
Director, an alert appears. You must make the cluster compatible again.
Prerequisites
Verify that you have log-in privileges and privileges for cluster modification for the vCenter Server system on
which the Data Director cluster runs.
Procedure
1 Log in to a vSphere Client that is connected to the vCenter Server on which the Data Director cluster runs.
2 Right-click the cluster and click Edit Settings.
3 Click VM Monitoring.
4 Select the Custom check box and specify custom settings.
These are the lowest acceptable settings. Values can be higher.
