HP StorageWorks Fabric OS 5.X Command Reference Guide (AA-RVHVB-TE, September 2005)

50 Fabric OS commands
Examples
To display the current policy and then change it from an exchange-based to a device-based policy:
• Exchange-based routing policy
With this policy, the path chosen for an ingress frame is based on:
Ingress port on which the frame was received
• FC address of the SID for this frame
• FC address of the DID for this frame
• FC Originator Exchange ID (OXID) for this frame
This policy allows for optimal utilization of the available paths as I/O traffic
between different (SID, DID, OXID) pairs can use different paths. All frames
received on a ingress port with the same (SID, DID, OXID) parameters takes the
same path unless there is a fabric event. See dlsSet for the definition of a
fabric event.
This policy does not support static routes. DLS always is enabled and the DLS
setting cannot change with this policy.
