"IPMP group failed on Solaris 9"

IPMP group failed on Solaris 9

Hi,

I have Solaris-9 server, V240.
I got alert that one of the interface on IPMP configuration, is failed. Found that two IPs (192.168.120.32 and 192.168.120.35) are not pingable from this server. These two IPs were plumbed on another server and that is decommissioned now. That is the reason, they are not pingable. For immediate fix, I plumbed both these IPs on another server and after that I was able to ping. I have seen this behaviour in other server, so I knew this may be the cause. But even after all IPs are pingable from routing table, I can't remove FAILED flag from ce0 interface.
Code:
# netstat -nr | grep 192.168.120.3

Please suggest, what I am missing here and should check ?

Thanks
