SAN Switch 200E FOS Upgrade From v5.2.1b to v5.3.0 Question-2

I need to make a Upgrade in a SW 200E from v5.2.1b to v5.3.0.

 

I have read in the Release Notes v5.3.0 this:

 

"In addition, prior to upgrading to v5.3.0 Device-based routing must not be in use, otherwise the upgrade will fail.

 

You can use the aptPolicy command to verify the routing policy."

 

I have executed this command and the results:

 

 

SAN_IBM_SW1:admin> aptpolicy
 Current Policy: 3

 

 3: Default Policy
 1: Port Based Routing Policy
 3: Exchange Based Routing Policy
SAN_IBM_SW1:admin>

 

I dont see Device-based routing , I see Port-Based Routing and Exchange-Based Routing.

 

Is ready for the upgrade?

 

Could anyone help me?

 

And if not too much trouble could someone explain which is device-based routing and Why is not in the command options?

 

Thanks a Lot.

Hi,

 

Yes, the switch is ready for the upgrade because it is using Exchange Based Routing.

 

On the other hand, the definition of Device based routing is:

 

device-based routing, in which the choice of routing path is based on the Fibre Channel addresses of the source device (S_ID) and the destination device (D_ID), improving path utilization for better performance

 

And it seems that it is no longer used since FOS 5.

 

Rgds,
