I have a Power 550 and a HMC，for testing HACMP, I create two lpar on the Power550,whose name is lpar1,lpar2

HMC using a eth0, ip address is 192.168.10.133

lpar1 using a eth0, ip address is 192.168.10.111

but when i want to move  physical adapters from lpar1 to lpar2，it appears:  

A RMC network connection to the source partition is not present. Verify the network settings on the partition and the HMC. If you select OK you will have to restart the partition for the resource changes to take effect.

here are some pictures for hmc configuration:
