1. If both trunk UTP cable connected, I can't ping gateway but can if only 1 utp cable connected

 

INFO:

-gateway 10.0.0.1

-connection like this

JUNIPER EX2200 -> HP Procurve 3400CL -> Gateway

-trunk ports in HP 21-24

in EX2200 44-47

As I read correct you are having two trunk ports between the HP device and ten Juniper switch?
With the same vlans on it ?? If ao you are creating a loop!!! That is why the Traffic stops flowing when you connect both utp cables between them.

The way this Works is to build aan aggregated ethernet channel between the two switchen based on lacp

To build an lacp link on an HP you must Google a bit

Marc solution work for me.

Now with 2 cable connected, I can still ping the gateway
