Upgrade GigaVUE Fabric Components in GigaVUE-FM for OpenStack

This chapter describes how to upgradeGigaVUE V Series Proxy and GigaVUE V Series Nodes. For more detailed information about UCT-V Controller, GigaVUE V Series Proxy and Node Version refer GigaVUE‑FM Version Compatibility Matrix

Refer to the following topic for more information:

Prerequisite

Before you upgrade the GigaVUE V Series Proxy and GigaVUE V Series nodes, you must upgrade GigaVUE‑FM to software version 5.13. For better performance, Gigamon recommends you to upgrade to the latest version.

Upgrade UCT-V Controller

Note:  UCT-V Controllers cannot be upgraded. Only a new version that is compatible with the UCT-V's version can be added or removed in the OpenStack Fabric Launch Configuration page.

To change the UCT-V Controller version follow the steps given below:

To change UCT-V Controller version between different major versions

Note:  You can only add UCT-V Controllers which has different major versions. For example, you can only add UCT-V Controller version 1.8-x if your existing version is 1.7-x.

  1. Under Controller Versions, click Add.
  2. From the Image drop-down list, select a UCT-V Controller image that matches with the version number of UCT-Vs installed in the instances.
  3. From the Flavor drop-down list, select a size for the UCT-V Controller.
  4. In Number of Instances, specify the number of UCT-V Controllers to launch. The minimum number you can specify is 1.

You cannot change the IP Address Type and the Additional Networks details, provided at the time of UCT-V Controller configuration.

After installing the new version of UCT-V Controller, follow the steps given below:

  1. Install UCT-V with the version same as the UCT-V Controller.
  2. Delete the UCT-V Controller with older version.

To change UCT-V Controller version with in the same major version

Note:  This is only applicable, if you wish to change your UCT-V Controller version from one minor version to another with in the same major version. For example, from 1.8-2 to 1.8-3.

  1. From the Image drop-down list, select a UCT-V Controller image with in the same major version.
  2. Specify the Number of Instances. The minimum number you can specify is 1.
  3. Select the Network from the drop-down.
  • You cannot modify the rest of the fields.
  • After installing the new version of UCT-V Controller, install the UCT-V with the same version.

Upgrade GigaVUE V Series Nodes and GigaVUE V Series Proxy

GigaVUE‑FM lets you upgrade GigaVUE V Series Proxy and GigaVUE V Series Nodes at a time.

There are multiple ways to upgrade the GigaVUE V Series Proxy and nodes. You can:

■   Launch and replace the complete set of nodes and controllers at a time.

For example, if you have 1 GigaVUE V Series Proxy and 10 GigaVUE V Series nodes in your project, you can upgrade all of them at once. First, the new version of GigaVUE V Series Proxy is launched. Next, the new version of GigaVUE V Series Nodes are launched. Then, the old version of V Series Proxy and nodes are deleted from the project.

NOTES:

o   When the new version of nodes and controllers are launched, the old version still exists in the project until they are deleted. Make sure the flavor determined during the configuration can accommodate the total number of new and old fabric nodes present in the project. If the flavor cannot support so many Virtual Machines, you can choose to upgrade in multiple batches.
o   If there is an error while upgrading the complete set of controllers and nodes present in the project, the new version of the fabric is immediately deleted and the old version of the fabric is retained as before.
o   Prior to upgrading the GigaVUE V Series Proxy and Nodes, you must ensure that the required number of floating IP addresses are available in the respective subnets. Otherwise, the upgrade will fail.
o   Do not configure floating IPv4 for an IPv6-only management /data subnet. Floating IPv4 is not applicable for IPv6-only subnet.
■   Launch and replace the nodes and controllers in multiple batches.

For example, if there are 18 GigaVUE V Series Nodes to be upgraded, you can specify how many you want to upgrade per batch.

To upgrade the GigaVUE V Series Proxy and GigaVUE V Series Nodes:

1.   Go to Inventory > VIRTUAL > OpenStack, and then click Monitoring Domain. The Monitoring Domain page appears.
2. On the Monitoring Domain page, select the connection name check box and click Actions

3. Select Upgrade Fabric from the drop-down list. The Fabric Nodes Upgrade page is displayed.

4. To upgrade the GigaVUE V Series Nodes/Proxy, select the Upgrade checkbox.
5. From the Image drop-down list, select the latest version of the GigaVUE V SeriesProxy/Nodes.
6. Select the Change Flavor checkbox to change the flavor of the nodes/proxy, only if required.
7. To upgrade the GigaVUE V Series Nodes/Proxy, specify the batch size in the Batch Size box.

For example, if there are 7 GigaVUE V Series Nodes, you can specify 7 as the batch size and upgrade all of them at once. Alternatively, you can specify 3 as the batch size, and launch and replace 3 V Series nodes in each batch. In the last batch, the remaining 1 V Series node is launched.

8. Click Upgrade.

The upgrade process takes a while depending on the number of GigaVUE V SeriesProxy and Nodes upgrading in your OpenStack environment. First, the new version of the GigaVUE V Series Proxy is launched. Next, the new version of GigaVUE V Series Nodes is launched. Then, the older version of both is deleted from the project. In the V Series Proxy page, click the link under Progress to view the upgrade status.

The monitoring session is deployed automatically.
