What precautions should I take into considerations before running the Load Balance Index Servers workflow?
The main precaution is to verify that you have other under-utilized index server MediaAgents that can receive the load from the overloaded one.
You should also verify that at least 5% of the total space on the disk that hosts the index cache on the overloaded index server is free. This disk space is used during the load balancing process.
Note
There is no need to disabled schedules or stop any jobs during the load balancing process; the index backend will take care of locking indexes and ensuring that everything is protected during the load balancing process.
Should I suspend any of the services on the main CommCell?
No, it is not required, and we do not recommended that you suspend services on the main CommCell. In order for the workflow to success, the CommCell must be up and running.
Should I run the workflow when there are no jobs running?
It is not required to run the workflow when there are no jobs running. However, the load balancing process may complete quicker if there are no jobs running.
What are the best practices I should follow when running this workflow?
There are three best practices that you should follow when running this workflow:
-
Verify that at least 5% of the total space on the disk that hosts the index cache on the overloaded index server is free.
-
Verify that the overloaded index server has shared data paths with other index servers, so those servers can be used for the load balancing operation. You can do this by verifying that there are more than one index server listed in the primary copies of the existing storage policies' data paths.
-
Verify that the index servers are connected, that Commvault processes are up and running on the servers, and that the servers can communicate with each other.
Note
You can also view the Index Server Load Report to view index load statuses, index load trends, and index size distributions across MediaAgents that are acting as index servers in a CommCell environment. For more information, see Index Server Load Report.
