Is there any kind of best practice procedure for installing Hotfixes on ClusterXL in HA mode without downtime?
I used to perform it in the following way:
1. Installing the HF on the Standby member
2. Performing the manual cluster switchover by issuing "clusterXL_admin down" on the Active cluster member
3. Installing the HF on the current Standby member and issuing "clusterXL_admin up" on it to push it back to the cluster
This procedure leads to the small drop of traffic during the switchover.
So, is there a better way to perform the installation on both member without, or with minimal, downtime?
I run into the following SK - sk107042 - ClusterXL upgrade methods and paths, and Connectivity Upgrade R77.x and R80.x Versions Best Practices document, but I'm not sure whether they are applicable for Hotfixes installation, or only for major/minor version upgrades.
