Setting an Affinity for a Process

You can set an affinity for Commvault processes. This is also referred to as CPU pinning.

Procedure

1. To the client computer, add the appropriate additional setting as shown in the following table.

   For instructions on adding additional settings from the CommCell Console, see Adding or Modifying Additional Settings from the CommCell Console.

2. Property	Value
   Name	To set an affinity for all processes, add All_AffinityMask. To set an affinity for a specific process, add process_name_AffinityMask. Replace process_name with the name of the process, for example, cvd_AffinityMask. Note If you set process_name_AffinityMask for a specific process, it overrides All_AffinityMask for the specified process. For example, for the CVD process, cvd_AffinityMask set to 1 overrides All_AffinityMask set to 4.
   Category	Session
   Type	STRING
   Value	The CPUs the process will execute on. Match the value to the CPU number, for example, enter 0 for CPU 0. Use a comma to separate multiple values, for example: 1,4,7. Valid values are 0,1,2,3,4,5,6, and 7.

3. On the CommServe computer, restart the services.
