Scaling an existing network pod
You can update a pod after it has been onboarded. This capability enables you to scale a pod when necessary. This topic discusses scaling an existing network pod and contains the following sections:
The following BMC Communities video (3:02) describes how to scale pod-level networks and use them in BMC Cloud Lifecycle Management. This involves adding resources to a BMC Network Automation pod and then synchronizing the pod (and sometimes a virtual cluster) in BMC Cloud Lifecycle Management.
Use case for synchronizing
For example, a pod might be running out of virtual ports for virtual machine (VM) provisioning because the pod was originally configured with one vswitch and a maximum of 120 virtual ports. You can update the pod with an additional access switch, which will provide more virtual ports for any new network containers that are created for the pod. You might want to add pod-level networks to existing pods to add more capacity.
Other scenarios for updating a pod include adding new load balancer nodes, firewalls, pod-level VLANs, or pod-level management networks into the pod.
Adding resources to the pod in BMC Network Automation
To add resources to a pod, you can simply update the pod in BMC Network Automation. (See Editing a pod in BMC Network Automation.)
You can add components to the pod, or you can remove nodes (Switch, Firewall, or Loadbalancer) from the pod that are no longer being used. Prior to removal, ensure that the node is not referenced in any network container.
If you are removing a hypervisor switch node from a pod and it is the only hypervisor switch being referenced by an onboarded cluster, then the pod synchronization operation will fail in BMC Cloud Lifecycle Management. To remove a hypervisor switch node from the pod, there must be one or more alternate switches common between the pod and the on-boarded cluster; otherwise, the pod synchronization fails to remove the switch from BMC Cloud Lifecycle Management.
Synchronizing the pod in BMC Cloud Lifecycle Management
- From the BMC Cloud Lifecycle Management Administration Console, click the vertical Workspaces menu on the left side of the window and select Resources.
- Under Quick Links on the left, click Pods under the General section.
- Select the pod you want to synchronize.
Click the Synchronize Pod iconto synchronize the network pod with any changes to the pod since it was onboarded.
When you add a new pod-level management network to an existing pod, synchronizing the pod only adds the new network to the CloudDB. You must create a new network container to use the newly created management network. For more information, see Extending the network on hypervisor nodes in the POD (version 4.6.03 and later) below.
- After the pod is synchronized, the associated virtual cluster must also be synchronized, as described in the section below.
Synchronizing the virtual cluster in BMC Cloud Lifecycle Management
To update the virtual hosts, virtual resource pools, and virtual disk repositories associated with a virtual cluster, complete the following steps:
- Under Quick Links on the left, click Resources under the Compute section.
- Select the virtual cluster you want to refresh from the table.
- Click the Synchronize Virtual Cluster icon .
After the activity is marked as complete, you can click the Refresh iconin the upper-right corner of the window to refresh the Resources table so that the newly onboarded resources appear in the table.
