In this lab I have used a custom core count to add a cluster to an SDDC and then delete this cluster:
Add a Cluster to the SDDC
Add Hosts to the Cluster
Remove a Host from the Cluster
Delete the Cluster from the SDDC
Add a Cluster to the SDDC:
You add a new cluster to the SDDC and configure a custom core count for the hosts.
From the VMware Cloud console browser tab, access the Summary tab of your Zerocloud SDDC. A Zerocloud label appears on the SDDC tile
On the VMware Cloud home page, click SDDCs on the left pane
Click the name of your Zerocloud SDDC. The Summary tab of the SDDC opens
On the Summary tab, click ADD CLUSTER on the Capacity and Usage tile. The Review SDDC Information page opens
In the Number of CPU Cores Per Host drop-down menu, select 16
In the Number of Hosts drop-down menu, select 1
Click ADD CLUSTER
A tile for the New Cluster and a tile for the existing Cluster-1 appear.
This process takes approximately 20 minutes when you use an SDDC that is supported with physical resources. In this Zerocloud lab, the process takes approximately 1 minute
Add Hosts to the Cluster:
You add hosts to the newly created cluster in the SDDC.
On the Summary tab, click ADD HOST on the Cluster-2 tile.
A warning appears: Elastic DRS is enabled for this cluster. Are you sure you want to manually add a host?
Click CONTINUE. The Add Hosts page opens
In the Number of Hosts drop-down menu, select 3
Click ADD HOSTS
The label DEPLOYING_HOSTS appears on the Cluster-2 tile. This process takes a few minutes.
A notification appears, confirming that the host is successfully added.
Remove a Host from the Cluster:
You remove a single host from an existing cluster in the SDDC.
On the Summary tab, select Remove Host in the ACTIONS drop-down menu on the Cluster-2 tile
A warning appears: Elastic DRS is enabled for this cluster. Are you sure you want to manually remove a host?
Click CONTINUE. The Remove Hosts page opens
In the Number of Hosts to Remove drop-down menu, select 1
Select the I understand that this action cannot be undone check box
Click REMOVE
The label DELETING_HOSTS appears on the Cluster-2 tile. The host removal process takes a few minutes.
A notification appears, confirming that the host is successfully removed.
Delete the Cluster from the SDDC:
You delete the cluster that you added
On the Summary tab, select Delete Cluster in the ACTIONS drop-down menu on the Cluster-2 tile
Confirm that you are aware of the consequences of deleting your cluster
Select the All workloads in this cluster will be terminated check box
Select the You will lose all data and configuration settings in this cluster check box
Select the You will lose all UI and API access to this cluster check box
Select the All public IP addresses for this cluster will be released check box
Click DELETE CLUSTER
The label DELETING_CLUSTER appears on the Cluster-2 tile.
The deletion process takes a few minutes. A notification appears, confirming that the cluster is successfully removed.
NOTE: The Cluster-1 tile no longer appears. The Cluster-1 tile is visible only when the SDDC has multiple clusters.
