Here is the quick-n-dirty on how to configure HP ProCurve series switch ports for dynamic LACP. My direct experience so far is with the HP ProCurve 2510G-24 and the HP ProCurve 2910al-24, but it should translate to similar switches. From other examples I've seen around the Intertubes, the differences you may encounter will be with the port names.

In the below example I am configuring a 4-port LACP trunk. That said, this exact configuration would work for two 2-port trunks.

Here we go: First, log into your switch. Then follow these series of commands:

 HP2910al> 
 HP2910al> config
 HP2910al(config)# int 1-4 disable
 HP2910al(config)# int 1-4 lacp passive
 HP2910al(config)# int 1-4 enable
 HP2910al(config)# 

Next, check the status of the ports. If you have no cables connected then it should look like this.

 HP2910al(config)# show lacp

                           LACP

   PORT   LACP      TRUNK     PORT      LACP      LACP
   NUMB   ENABLED   GROUP     STATUS    PARTNER   STATUS
   ----   -------   -------   -------   -------   -------
   1      Passive   1         Down      No        Success
   2      Passive   2         Down      No        Success
   3      Passive   3         Down      No        Success
   4      Passive   4         Down      No        Success

 HP2910al(config)# 

If you do have cables connected, and the attached network node is properly configured, then this is what you should see after executing the show lacp command.:

 HP2910al(config)# show lacp

                           LACP

   PORT   LACP      TRUNK     PORT      LACP      LACP
   NUMB   ENABLED   GROUP     STATUS    PARTNER   STATUS
   ----   -------   -------   -------   -------   -------
   1      Passive   Dyn1      Up        Yes       Success
   2      Passive   Dyn1      Up        Yes       Success
   3      Passive   Dyn1      Up        Yes       Success
   4      Passive   Dyn1      Up        Yes       Success

 HP2910al(config)# 

Dynamic LACP configuration can be done only in the ProCurve command line interface. Static LACP trunks can be configured at the CLI or the ProCurve's menu system. For an example of this read How to configure Ethernet Bonding with LACP on Debian 5 Linux.
