Configuring Synchronous Replication on a Volume Collection
You can configure synchronous replication for the volume collection. A volume collection includes a set of protection schedules for creating snapshots of each associated volume at set intervals. The protection schedule specifies the downstream partner where the volume and snapshot data is replicated.
- All upstream volumes in a synchronously replicated volume collection must belong to the same pool.
- Two different volumes with the same name in the downstream pool are not supported.
- All synchronous replication schedules must use the same downstream pool partner.
For a new synchronous replication configuration, downstream volumes are automatically created. If any downstream volumes exist from previous synchronous replication, they are re-used. The downstream volume inherits the state of the existing upstream volume (either online or offline).
- A downstream volume is created in the pool partner that has the same name and is automatically added to the volume collection.
- The volumes in the downstream volume collection inherit the serial number and the existing ACLs from the upstream volumes.
- The volumes in the downstream volume collection are brought online to export the iSCSI standby paths.
