HWNPM4028W Performance data cannot be collected because the security role authority of the user account user name for accessing device identifier is not sufficient.

Explanation

The user account that is used to log on to the storage system does not have the required authority for collecting performance data. For versions of IBM Spectrum Virtualize earlier than 8.3.1.2, the user must have the Administrator or SecurityAdmin role.

Action

If the resource is a Spectrum Virtualize storage system, complete one of the following tasks:
  • Open the management GUI for the storage system and change the role of the user account to either 'Administrator' or 'SecurityAdmin'.
  • In the IBM Spectrum Control GUI, go to the Block Storage Systems page, right-click the resource, and select Connections -> Modify Connection. Enter a different user name that has sufficient authority for collecting performance data. You might need to stop and restart the performance monitor to have these changes take effect. Right-click the resource again and select the appropriate Data Collection options.
