Removing all mirror relationships

This procedure is useful for replacing all the backup SDs in a span.

1. To prevent the server from trying to load the on-disk configuration from the S-Vols in a later step, use the span-deny-access --secondaries command.
2. To remove the mirror relationships from the span, use the span-break-mirrors command.
3. Use your storage configurator to break the mirror relationships.
4. Do one of the following:
   • Use your storage configurator to delete or reinitialize the former S-Vols, leaving the production SDs intact.
   • Use the sd-wipe-cod-signature --danger-ignore-sd-licensing command to erase the on-disk configuration signatures on the former S-Vols, so that they do not confuse the server.
   • Use the sd-span-cod-reads --resume command to tell the server to resume loading the on-disk configuration.
5. To reuse the former S-Vols on this cluster, use the sd-allow-access command to relicense them.
