This page provides information on how to edit vCenter compute resources and how to manage their data store joins. 

Edit Details of vCenter Compute Resource

  1. Go to your Control Panel > AdminSettings menu.
  2. Click the Compute Resources icon.
  3. Click the Actions button next to the vCenter compute resource that you want to edit, and then click Edit.
  4. On the page that follows, change details as required:
    • Label - enter a compute resource label
    • Compute Resource Type - select the vCenter compute resource type
    • Operating System Type - select the operating system type of the virtual servers that can live on this compute resource:
      • Any OS - when this option is selected, any VS with any operating system will live on compute resource. By default, each compute resource will be created with the Any OS option. The existing compute resources also will have the Any OS set.
      • Windows only - when this option is selected, only VSs with the operating system Windows will be living on this compute resource. This compute resource will not be available for selection when creating a Linux or FreeBSD VS, nor when migrating a VS.
      • Non-Windows - when this option is selected, only VSs with the operating system Linux or FreeBSD will be possible to create on this compute resource. This compute resource will be skipped for Windows-based VSs in VS creation wizard, or when migrating a VS. Also when failover happens, Windows-based VSs won’t migrate to this compute resource.
    • CPU Units - adjust the slider to set the desired amount of CPU units for this compute resource
    • Enabled - whether the compute resource is enabled or not (compute resources that are not enabled cannot be used to host VSs)
    • Collect Stats - move the slider to the right to collect statistics for this compute resource
    • Compute Zone - the compute zone to which the compute resource is assigned
    • API URL - set the vCenter API URL - e.g.
    • Login - specify the vCenter login
    • Password - specify the vCenter password
  5. Click Save.
  6. Go to vCenter compute resource's label > Actions > Resource Options.

  7. Click Resync vCenter to import all networks and datastore that are not currently synchronized in OnApp from vCenter.

Manage vCenter Compute Resource Data Stores

Data stores can easily be attached and removed from vCenter compute resources. This association between a compute resource and a data store is called a data store join.

You can add data stores to a compute resource only if they are assigned to the zones of the same type. For more information, refer to Zone Types.

To add/remove data store joins:

  1. Go to your Control Panel > AdminSettings menu.
  2. Click the Compute resources icon.
  3. Click the vCenter compute resource's label that you want to manage data stores for.
  4. On the page that appears, click the Actions button, point to Management Options, and select Manage Data Stores.
  5. On the following page, you'll see a list of all data stores currently associated with this vCenter compute resource.

To remove a data store join, click the Delete icon next to it. You'll be asked for confirmation before the store is removed.

To add a new data store join, select a data store from the drop-down list, and then click Add Data Store.
