How to create port channels across the switches?

[airwolf09]

we have 5406 and 5412 switches. 5412 is the root switch with a trunk to 5406.

we have netapp 2040 bonding 4 nics as lacp vif on each head.

if I split the 4 nics to make 2 nics on 5412 and 2 nics onf 5406 switch. how can I create a port channels across the switches?

Creating an aggregated link (ie LACP) in ProCurve is easy:

trunk b1-b4 trk1 lacp

Doing that over 2 ProCurve switches with ProVision ASICs will require the use of distributed trunking. you create a dedicated link (ISC) between the 2 switches, and then you can create a distributed LACP link over the 2 switches. There are several documents and the manuals that explain that config.
