The vRealize Automation Solution Is Required for Workload Placement to Operate Properly
Workload placement is based on individual machines, and placement is done at the machine level. When
vRealize Automation and vRealize Operations Manager are installed together, the vRealize Automation
Solution must also be installed.
The solution, which includes the management pack and adapter, identifies the clusters on which the
rebalance container or move VM actions are disabled. The rebalance action is disabled on the custom
data center to which the cluster belongs.
n
For unmanaged vRealize Automation clusters that belong to a custom data center that does not have
any managed vRealize Automation clusters, the move VM and rebalance container actions are
enabled. For managed vRealize Automation clusters, these actions are disabled.
n
In vRealize Operations Manager, the vRealize Automation Adapter causes VMs on clusters that map
reservations not to be available for move or rebalance.
Caution The vRealize Automation solution must only be installed on a single
vRealize Operations Manager instance.
High Availability Is Enabled, but Must Be Disabled
When HA is enabled, if vRealize Operations Manager is down, the timeout used for workload placement
to call vRealize Operations Manager might fail.
vRealize Automation logs workload placement errors in the catalina.out log file.
vSphere Endpoints in vRealize Automation Are Not Monitored
vRealize Operations Manager is not monitoring the vSphere vCenter Server instance that contains the
reservation clusters.
If vRealize Operations Manager does not recognize the vRealize Automation candidate reservations for a
cluster, datastore, or datastore cluster when it attempts to place them, it ignores them. In the placement
response, vRealize Operations Manager communicates to vRealize Automation that it does not recognize
them.
As a result, in the placement details on the request execution, vRealize Automation displays a warning
icon on the candidate reservation to indicate that it is unrecognized.
When Mismatches Occur, vRealize Automation Appears at the Top of the List
vRealize Automation and vRealize Operations Manager manage different views of the infrastructure. But
they must both manage the same instances of vCenter Server in the same infrastructure.
Must identify disconnects and mismatches, and display details.
What to Do If the vRealize Automation Adapter Is Down
The initial placement always honors the list of destination candidates that it receives from
vRealize Operations Manager, such as when a user adds a cluster immediately after installation.
