168 Installing and maintaining firmware
Message
Cannot download to 5.1 because Device Based routing policy is not supported by 5.1. Use
aptPolicy
to
change the routing policy before proceeding.
Probable Cause and Recommended Action
The firmware download operation was attempting to upgrade a system to Fabric OS v5.1.0 with
device-based routing policy selected. Device-based routing policy is not supported in firmware v5.1.0, so
the firmware download operation was aborted.
Disable the switch and change the routing policy selection to one of the following supported selections on
firmware v5.1.0 using the
aptPolicy
command, and then retry the firmware download operation. The
supported selections are described briefly below:
policy 1 Port-based routing policy
With this policy, the path chosen for an ingress frame is based on:
1. Ingress port on which the frame was received
2. Destination domain for the frame
The chosen path remains the same if Dynamic Load Sharing (DLS feature is not
enabled. If DLS is enabled, then a different path might be chosen on a fabric event.
Refer to the
dlsSet
command for the definition of a fabric event.
This policy may provide better ISL utilization when there is little or no oversubscription
of the ISLs.
NOTE:
Static routes are supported only with this policy.
policy 3 Exchange-based routing policy
With this policy, the path chosen for an ingress frame is based on:
1. Ingress port on which the frame was received
2. FC address of the SID for this frame
3. FC address of the DID for this frame
4. 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. Refer to the
dlsSet
command 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.
