How to change IP Helper setting on an HP switch

After a recent change in DHCP servers, we had to update the IP helper setting so that workstations and phones on other VLAN’s could get DHCP addresses (they were getting 169.x addresses after changing DHCP servers).  Here is an example of the procedure:

Portland core switch (all their floors trunk into the core switch):
enable
config term

show ip helper-address
vlan 2 ip helper-address 192.168.0.45
show ip helper-address
no vlan 2 ip helper-address 192.168.0.12
show ip helper-address

Did same for VLAN 2 and 10

Seattle core switch:
enable
config term
show ip helper-address
vlan 1 ip helper-address 192.168.0.45
vlan 10 ip helper-address 192.168.0.45

show ip helper-address
no vlan 1 ip helper-address 192.168.0.12
no vlan 10 ip helper-address 192.168.0.12
show ip helper-address
