the parameter ha= ?

[antares atlantide]

Hi,


# /etc/bootptab example for FAI
# replace FAISERVER with the name of your install server

.................

# now one entry for each install client
demohost:ha=0x00105A240012:bf=demohost:tc=.failocal:T172="verbose sshd 
createvt debug":
ant01:ha=0x00105A000000:bf=ant01:tc=.failocal:T172="sshd":

I want to know how you obtain the parameter ha= ?

Thanks Antares
