Trunking (LAG)
Trunking in HP terms is bundling 2 or more ports together to create a larger bandwidth port. In Cisco terms it is referred to as Etherchannel. The connecting switch must also be configured for trunking.
#trunk 1-4 trk1 trunk (Creates a 4 port bundled static trunk)
#trunk 1-4 trk1 lacp (Creates a 4 port bundled LACP trunk)
#show trunk (Shows Port name, connection speeds, trunk group and type trunk | LACP)
#show trunk 4 (Shows trunk information for the interface 4 member)
#show lacp (Displays information about lacp status on port members)
Verifying Link Partner is using LACP Fast/Short vs. Slow/Long
I have not discovered if there is a parameter that allows you to set the Procurve to LACP short/long per port as no other switching platforms. The only way I know to do so this is to set the Procurve to be a passive LACP members, ensure the link partner is using active LACP and set the link partner (6300-AOS-CX in this case) to LACP short/fast. This will force the Procurve to set its interfaces to LACP short/fast.
Procurve
3810M(config)# trunk 1-2 trk127 lacp
3810M(config)# int 1-2
3810M(eth-1-2)# lacp static active
3810M(eth-1-2)# exit
Note: This sets the interface to be a static active LACP member which is kind of counter-intuitive. But if you use the 'lacp active' setting then this sets the ports to be part of a dynamic (or dyn) LAG which is not what we want here.

Link Partner
With the link partner (6300-AOS-CX in this case) set to LACP short/fast and LACP Active and the Procurve set to LACP active the link Partner sees the Procurve interfaces set to long/slow. I do not know if there is a way to manually set the Procurve to short/fast manually.

Forcing the Procurve to be LACP short/fast
With Link partner (6300-AOS-CX in this case) set to LACP short/fast and LACP Active and the Procurve set to LACP passive the Procurve will automatically match the settings on the Active LACP link members and the link Partner sees the Procurve interfaces set to short/fast. This is the only way to get the Procurve to set to LACP short/fast (that I know of.)
On the Procurve:
3810M(eth-1-2)# lacp static passive
3810M(eth-1-2)# exit
On the link partner (6300-AOS-CX in this case)
6300(config-lag-if)# show lacp interfaces
