FSPM uses the HP-UX 11i v3 multipathing driver to provide paths for reading and writing data to LUNs on the Oracle FS System.
The multipathing driver:
- Controls and manages all data paths to the Oracle FS System LUNs
- Groups multiple data paths to an Oracle FS System LUN and presents this group to the host operating system as a single LUN or drive
- Determines which data paths to use
- Identifies and uses optimized data paths when possible
- Handles data path failover and failback
- Manages data path errors
A path that provides the best performance is referred to as an optimized path and is the preferred path for data transfer.
