regrding host id in disks

Hi,

I have set up & initialised a disk and output of 'vxdisk list <disk>'
shows
...
hostid:    ochpt9
disk:      name=testdisk id=1171622480.1304.ochpt9
group:     name=testdg id=1171622578.1307.ochpt9
...
...

Now, we realized that the host id is not correct and changed it to ochpt10
using the command 'vxdctl hostid ochpt10'

Now, the hostid alone has been changed but, the old hostid still remains
in the the diskid part and groupid part.. 
....
hostid:    ochpt10
disk:      name=testdisk id=1171622480.1304.ochpt9
group:     name=testdg id=1171622578.1307.ochpt9
...
...
What will be the impact of having the old hostid and how to change it to
ochpt10?
