Hello, Please I need your advice regarding the below: We have 3 x HP 3PAR V400 with 2 nodes each, we are using the SLD synchronous long distance scenario for the replication as follow: [from A > B Sync and A > C Periodic] I need to test failover of one Remote Copy group selectively from A to C while keeping the synchronous replication from A to B operational (for the same RC group) And then after test working on the C storage, revert back and restore replication from A to C (i.e. smashing all altered data on C while doing the test). I know how to do it in normal 1 to 1 replication but I’m not sure in SLD scenario. Thank You and Regards, Ziad Melhem |

only what I need to know, is it possible to failover only the periodic part a RC group in an SLD scenario, and keeping the synchronous replication working normally? Thanks, Ziad |

According to this video's diagram, it should be possible. However, it may require you to temporarily cut the connection between A -> C during testing. May want to check with support to confirm. http://www.youtube.com/watch?v=bZN_9024xsM Interesting design and concept though. -Jason |
