HP XP P9500 Storage - Manual (Page 132)

If you delete WWN from the PFC targets by using the PFC group name, the PFC setting and the
group under the specified port are deleted. If the same PFC group name is set to another port,
only the PFC setting of the specified port is deleted.
Resource group function and restrictions when running Performance Control
When you use the resource group function, the range of operation is limited per port of resource
group by Performance Control. The threshold value, the PFC name, and the PFC group name,
which are managed in the entire system, are common among the resource groups.
When you perform Performance Control operations using the resource group function, share the
threshold value that the storage administrator determines among users of resource groups. Determine
rules for PFC names and PFC group names including port names to avoid redundant names between
ports.
