Update the Appliance Software in a Central Management Cluster

To update the appliance software on Secure Web Gateway appliances that run as nodes in a Central Management cluster, perform the update procedure on one of the nodes and update this node as the last of all.

TIP: We recommend creating a backup of the current configuration before the update.

  1. Install a repository with the product version you want to update to on every appliance that is a node in the cluster:
    1.  Log on to an appliance from a system console using SSH.
    2. Run this command:

yum install yumconf-<version number>-mwg

yumconf-<version number>-mwg is the repository name. The digits of the version number must be separated by dots.

  1. Log on to the interface of one appliance in the cluster for performing the update.
  2. Update every appliance in the cluster, except the appliance where you are working:
    1.  On the appliances tree, select an appliance.
    2. On the toolbar above the settings pane, click Update appliance software.
  3. When all other appliances are running their updates, update the appliance where you are working:
    1. Select the appliance on the appliances tree.
    2. Click Update appliance software.

The appliance software is now updated on all nodes in the cluster.

If the nodes in a cluster are assigned to different network groups, with some nodes being members of more than one group, we recommend that you:

  • Perform the update procedure from one of the nodes with multiple membership.
  • Update any other node with multiple membership at the end of the procedure.
  • Update the node where you are working last.

For example, you have network group A with nodes 1, 2, 3, 4 and network group B with nodes 3, 4, 5, 6, where 3 and 4 are members of both groups:

  • Choose node 3 or 4 for performing the update procedure
  • Update nodes 1, 2, 5, 6 first, then 4 (if you have chosen 3 to perform the procedure), and finally 3.
