Hi, question on remote copy.
Is it possible to limit (QoS) traffic over the fibers when activating full sync operations. It seems the sky is the limit and all resouces go to that full resync, triggering DELACK's etc. .

Not that I know of. Are you seeing delack on source or target and what type of array and configuration?

This a 20K configuration. In this case a SLD configuration with synchronous link between A and B an async link between A and C. Delack was seen on target C. Full,t inital sync was triggerd only between A and C. I do think due to wrong syntax used to delete/add VV to RCgroup . And yes again , it feels like all resources are used to make the sync asap. Throtteling would be nice to be in place, but no idea how to do. Maybe create VVset for all involved target VV's and put some QOS in place. No real issues seen but of course piek was seen on DWDM infra serving all replication trafic beteen all of our production 3PAR systems.
