If you encounter a
problem, such as network outage or application startup failure, even after
sequencing the NICs, check the downloaded version of the bundle. It is possible
that you might have downloaded a previous version of the bundle that resulted
in the inconsistent state of the NICs. Verify that the bundle has the following
If there is network
outage or application startup failure following upgrade, as a result of using
an older bundle, you can re-image the failed node with Cisco ISE 1.2 software,
register it to the old deployment, and restore the operations backup (if the
node had a Monitoring persona). Then, you can attempt to perform the upgrade
using the latest bundle again. This recovery step is suitable for a Secondary
Administration Node, which is the first node to be upgraded in a deployment.
For other nodes in the
deployment, you could use the same step or directly reimage the node with Cisco
software, register it to the new deployment, and restore the
operational backup, if applicable.
Ensure that you follow
the steps mentioned in the Sequence Network Interface Cards (NICs) after
Pre-Upgrade Check section.
If it is a standalone
node, you can re-image the node with Cisco ISE
software and restore the configuration and operations backup.
If all the above steps
fail and you encounter failed network connectivity for ISE post upgrade,
contact Cisco TAC.
