A physical snapshot is full copy of the physical source LUN on the primary Oracle FS System at a specified point in time. You can map the LUN copy from the Oracle FS System to any host that has access to the Oracle FS System SAN.
To create a physical snapshot, you capture a given point in time and create a full copy of a physical source LUN on either the primary or the secondary Oracle FS System.
From the Oracle FS System Manager, you first create a LUN on the secondary Oracle FS System. This LUN must be the same size or larger than the target LUN on the secondary Oracle FS System. Then, on the secondary Oracle FS System, you map the LUN to an appliance initiator for a target (AIT) port. The mapping enables the Oracle MaxRep Replication Engine to see the LUN, so that you can create the physical snapshot. After you release the physical snapshot, you can map the snapshot to a different host for validation.
