Set REC Bandwidth Limit
Overview
This function sets the bandwidth limit for the copy path.
Registering the Advanced Copy function license or the Storage Cluster function license (*1) is required to use this function.
*1 : The Storage Cluster function license must be registered using ETERNUS SF Storage Cruiser.
This function enables the Initiator (copy source) to limit the bandwidth for sending data in the copy path. The bandwidth limit can be set for each path.
The bandwidth limit setting is not included in the copy path information. Therefore, a bandwidth limit setting for the unchanged path remains even when a copy path was created after the copy path information had been changed.
Note that the bandwidth limit for the path is also deleted when the copy path has been deleted.
