7. Confirm that the Publisher node and all Subscriber nodes in the cluster are in sync before starting the
upgrade.
8. On the Software Updates page, enter the Subscription ID.
9. On the Publisher node, download the W-ClearPass 6.6 upgrade image from the Software Updates portal
(see Software Updates and OnGuard Settings on page 693).
The Upgrade tool automates the process of copying over the upgrade image to the selected subscribers in
the cluster.
10.If you are upgrading on a reverted system (retrying an upgrade), you will need to replace the contents of
certain directories first before triggering the new upgrade. Please contact Support (see Contacting Support
on page 1), who will assist you with the following tasks:
a. Copying the contents of the /var/avenda/platform/store/updates/backup/* directory to the
/var/avenda/platform/store/updates/ directory.
b. Clearing the contents of the /var/avenda/tips/upgrade/db/* directory.
c. Restarting the cpass-admin-server on the Publisher.
11.When a particular node's version information is set to "UNKNOWN," it means the Publisher is not able to
contact the remote node.
If a node has been disabled and gone out of sync, the Cluster Upgrade interface might not detect the status
until the patch failure has occurred, after which the failed or inaccessible node is marked as UNKNOWN.
In such cases, confirm the status of the cluster sync and the service status of Async network services
(navigate to the Administration > Server Manager > Server Configuration > Service Parameters
page, then select Async network services from the Select Service drop-down).
d. In virtual machine environments, W-ClearPass Policy Manager virtual machine host date and time
settings should be in sync with that of the VMware vSphere Hypervisor server, Microsoft Hyper-V server,
or KVM hypervisor server that is hosting the instance. Otherwise, you might see inconsistent data in
"Time Taken" columns of the Upgrade interface.
