A PowerMax customer has an existing Masking View for a large database environment. The parent Storage Group in this Masking View has three child Storage Groups with different Service Levels (SLs).
The customer has been experiencing some database performance issues and wants to set the SL to Platinum for all the devices.
When the storage administrator attempts to set the SL on the parent Storage Group, they receive an error and the operation fails.
What is the cause of the error?
