Configuring SnapVault relationships
When you configure SnapVault relationships, the primary storage controllers must have a valid SnapRestore and SnapVault license installed. The secondary storage must have a valid SnapVault license installed.
Enable SnapVault and NDMP on the primary and the secondary storage controllers.
hana1a> options snapvault.enable on hana1a> ndmp on hana1a> hana1b> options snapvault.enable on hana1b> ndmpd on hana1b hana2b> options snapvault.enable on hana2b> ndmpd on hana2b>
On all primary storage controllers, configure the access to the secondary storage controller.
hana1a> options snapvault.access host=hana2b hana1a> hana1b> options snapvault.access host=hana2b hana1b>
Using a dedicated network for replication traffic is recommended. In such cases, the host name of this interface at the secondary storage controller needs to be configured. Instead of hana2b, the host name could be hana2b-rep.
On the secondary storage controller, configure the access for all primary storage controllers.
hana2b> options snapvault.access host=hana1a,hana1b hana2b>
Using a dedicated network for replication traffic is recommended. In such cases, the host name of this interface at the primary storage controllers needs to be configured. Instead of hana1b and hana1a the host name could be hana1a-rep and hana1b-rep.
