Pairing clusters, storage domains, and LSUs
To support optimized duplication and Auto Image Replication (AIR), NetBackup must establish a replication relationship between the source and target SpanFS clusters, along with their associated storage domains and logical storage units (LSUs).
In NetBackup, the pairing for Auto Image Replication (AIR), is established when you add a replication target to a disk pool during disk pool creation or by updating an existing disk pool. For optimized duplication, it is done during SLP creation of optimized duplication.
Before you add the replication target, ensure that:
Source and target SpanFS clusters are reachable over the network.
Storage domains and LSUs exist on both the source and target SpanFS clusters.
Both SpanFS clusters are added as storage servers in NetBackup.
You have NetBackup administrator privileges.
When you add a replication target to a disk pool, NetBackup performs the following actions:
Associates the source disk pool with a target storage server.
Identifies the corresponding target storage domain and LSU.
Establishes trust and communication between the source and target SpanFS clusters.
Enables inter cluster data transfer required for replication.
To pair clusters, storage domains, and LSUs by updating an existing disk pool
- In the NetBackup web UI, click Storage > Disk storage, and then select the Disk pools tab.
- Select the disk pool to update.
- Click Edit.
- Navigate to the Replication page.
- Click Add to add a replication target.
- In the Add replication targets window:
Under Select trusted primary server, select the trusted primary server.
Under Select target storage server, select the target SpanFS storage server and the appropriate target volume (LSU).
These settings apply only to Auto Image Replication (AIR) between NetBackup domains.
- Click Add.
- Save the disk pool configuration.
