Okay, obvious question i'm afraid, where is that device ie. what switch is it connected to and is that switch on the other end of the trunk ? Whether it is or it is further down the line on another switch can you check all the trunk links back to the 6500 from the switch the device is connected into and make sure vlan 222 is allowed on all trunk links and that it is not blocked.
Could you also check the device is up and running and that it has no inbuilt firewall that would stop it responding.
Oops, missed that, thanks for pointing it out. What is gi5/1 connected to ie. is it directly connected to the fw (by which i assume you mean firewall) or is there another switch in between (or multiple switches). Perhaps you could explain the topology.
If multiple switches can you check their status, specifically the vlan database ie. "sh vlan brief" and make sure vlan 222 is present.
