Cisco Prime Infrastructure patch 2.1.1 - HA issue

Question

Hello,
I have a problem with the Cisco Prime Infrastructure patched to version 2.1.1. I did exactly what Installation Guidelines say:
http://www.cisco.com/c/en/us/td/docs/net_mgmt/prime/infrastructure/2-1-1/release/notes/cpi_rn.html
– Install the Prime Infrastructure 2.1.1 patch by using the Administration > Software Updates page on the primary server.
– Restart the primary server.
– Verify that the patch installation is complete. If you find the installation complete, decommission and reinstall the secondary server and add it back to the primary server.
I reinstalled HA server and I'm trying to add it to HA but I get "Failed to authenticate - Primary(xx.xx.xx.xx) and Secondary(xx.xx.xx.xy) PI version does not match"
Can you help me with that? What I'm doing wrong? or maybe this patch is not prepared to work in HA mode?
Regards

Answer 1

Symptom:
The installation instructions of PI 2.1.1 patch in a High Availability environment are not accurate and following these steps will result in the inability to re-pair the Primary and Secondary servers.
Conditions:
If the instructions are followed, then when the user attempts to re-pair the servers, an error will be encountered:
"High Availability Registration Failed - Failed to authenticate - Primary (x.x.x.1) and Secondary (x.x.x.2) PI version does not match".
Instead, the following steps have proved to work correctly:
1. Upload and install patch on primary.
2. Upload and install patch on secondary.
3. Stop NCS services on secondary
4. Stop NCS services on primary
5. Start services on secondary
6. Start services on primary
7. Re-pair HA servers from primary
Workaround:
Workaround 1:
On the secondary, go under root and issue:
# cd /opt/CSCOlumos/bin/
# ./hamode.sh primary
Answer 'yes' when prompted.
Go to admin user and execute
# ncs stop
After the services are stopped:
# ncs start
When the services are back up, login to the secondary GUI as you would login to a primary server
Go under Administration > Software update, upload the patch and install it.
Go to admin user and execute
# ncs stop
After the services are stopped:
# ncs start
When the services are up, go under root and issue:
# cd /opt/CSCOlumos/bin/
# ./hamode.sh secondary
Answer 'yes' when prompted.
Go to admin user and execute
# ncs stop
After the services are stopped:
# ncs start
After the message that services started successfully on the secondary, initiate a new High Availability configuration from the primary. Now the synchronization between the two servers should succeed.
Workaround 2:
Redeploy or reinstall the Primary server, restore the backup which was taken prior to applying the patch, reconfigure the High Availability and continue with the steps described in the Conditions section.
