Hi,
Here is the process of patch installation for the ACS cluster:
On the secondary servers:
- Go to each secondary server under System Administration - Operations - Local Operations - Deployment Operations.
- From here select the option Deregister from Primary . (This might take 5-10 minutes to be complete)
- This will restart the services on each secondary server while doing this process.
On the primary server:
- Go to the primary server under System Administration - Operations - Distributed System management.
- From here please select each secondary server under the Secondary Instances and make sure to deregister each entry first and then deleted from this section.
Once each secondary server is showing as primary / stand-alone unit please proceed and install the patch you need on each server through the CLI.
Instructions on how to install the patch
=================================
1. open CLI console
2. define new repository in which the patch file resides
3. issue: 'acs patch install *.tar.gpg repository YOUR_REPOSITORY'
4. verify installation by getting the following version information via CLI by issuing:
#show application version acs

Once the patch is install on each server you can now proceed and add servers back as secondary servers.
On each secondary server
- Go to System Administration - Operations - Local Operations - Deployment Operations.
- Fill out the registration fields (this information needs to be the one for the primary server) The credentials you will use here are the ones for the web GUI access. On the primary instance please include the IP address of the primary server.
- Wait 5 - 10 minutes for the process to be complete.
On primary server
- Monitor the synchronization process under the under System Administration - Operations - Distributed System management.
- This process might take around 5-10 minutes however this might be longer depending on your environment.
- All secondary instances under this section should show as updated after the synchronization is complete.
Hope the process is clear enough.

Aditya
