Dhcp static binding, WS-X45-SUP7-E, sso

Question

Hello, i try to use dhcp static mapping. At WS-X45-SUP7-E in sso mode. It's already good working for me, but i receive this error:
000243: 000202: *Nov 15 14:01:29.540: %DHCPD-4-HA_CONFIG_MISMATCH: STANDBY:DHCP pool mit_stb configuration on Active is not matched on the Standby.
This is my dhcp config.
ip dhcp pool mit_stb
   origin file ftp://10.6.1.240/static_pool_mit_stb.txt
   default-router 10.50.0.254
How can i solve this error?
UPD: In scope of fixing this error i trying a force-switchover and in result all static bindings was drop, because standby supervisor doesnot know about it. After "no service dhcp" and "service dhcp" commands static bindings is up and network still working good, but upper error was comeback in logs. Therefore my system have no redundancy for this function.
my running-config redundancy section:
redundancy
mode sso
main-cpu
  auto-sync standard
Has anyone used this function in SSO mode?

Hi,
In this case you need to make sure that the new sup module is running the same IOS version that the current supervisor, if that is the case then when you insert the new one it will get in sync with the active module and all config will be loaded into the new module, at that point you can use the show module and show redundancy to ensure that the 2 supervisors are in SSO mode once you confirm that then you can force a switchover to the supervisor in slot 3 and once he has take over the box control then you can remove the slot 4 sup.
Hope this helps.
