Sorry, I don't see a question or quite understand the issue (if there is one). |

Popular standard is to have 2 SAN switches connected to each array and host. With plain remote copy and RCFC, you will have to manually rezone and export to 'fail over'. Using "Peer Persistence" feature is probably what you want to deploy. Hosts are zoned to BOTH arrays and use ALUA to know which one is primary and which one is standby. If you only have 2 switches, you should configure them as SAN-A and SAN-B, and attach both arrays to both switches, same for your hosts. Make sure to read up on how Port Persistence works to make sure your cable it up correctly. |
