You mentioned multiple RCGs. Can you start each one using "<FONT face="courier new,courier">startrcopygroup -wait</FONT>" so only one is re-syncing at a time?</P> Tue, 13 Jun 2017 15:28:38 GMT Sheldon Smith 2017-06-13T15:28:38Z https://community.hpe.com/t5/hpe-3par-storeserv-storage/starting-synchronous-remote-copy-with-low-priority/m-p/6967890#M3309 <P>Hi</P><P>We have to stop RC groups one by one for some maintenance operations. Starting groups again will cause a large impact to all hosts: 30 - 40 ms delays before the sync is ready. Starting only one group with 2 TB of volumes inside takes 20 minutes before the sync state is green and the whole time it causes delays.</P><P>Is there an option to start remote copy sync again with lower priority?</P><P>2-node 8200, 3.2.2 MU4</P> Tue, 13 Jun 2017 07:40:49 GMT https://community.hpe.com/t5/hpe-3par-storeserv-storage/starting-synchronous-remote-copy-with-low-priority/m-p/6967890#M3309 stomko 2017-06-13T07:40:49Z https://community.hpe.com/t5/hpe-3par-storeserv-storage/starting-synchronous-remote-copy-with-low-priority/m-p/6967956#M3311 <P>No. The "<FONT face="courier new,courier">startrcopygroup"</FONT> command has no priority option.<BR />It would be a trade-off, but could you wait and start it later during off-hours?
