Why do I sometimes get an error message saying that the system configuration has
changed and that I should re-run the Policy Advisor?
■ Policy Advisor gathers internal state information for all of the various virtual volumes in the
system. If a virtual volume is deleted while this information is being processed, Policy
Advisor needs to be re-run in order to perform an accurate analysis of the entire system.
This only applies to virtual volumes that provision space from CPGs and virtual volumes that
provision space directly from LDs. Snapshots and TPVVs can be created and deleted without
effecting the Policy Advisor analysis and tuning operations.
I just added 15K FC drives to an InServ with 10K FC drives and PolicyAdvisor is not
suggesting tuning operations that include the new 15K drives.
■ Use the -norpm option to allow PolicyAdvisor to suggest tuning operations for all drives in
mixed speed FC drive configurations.
