The Failover status of iHealth

Thanks for your advice！ I have 2 BigIP 7000S platforms and the module contain LTM V11.4.1 Following the initial set up flow（Run the Setup Utility） to create Sync-Fail status （I have created Device-Group and choose the Network failover function） Power off or changing the platform status Active-Standby to Standby-Active and working… But when I upload the qkview to iHealth… The list in iHealth Status->Failover->Network->Peer IP address show that I did’t configure Peer IP…. Here is the Link https://www.dropbox.com/s/tklth7xjmycwrn5/sampo.png But I truly trust each other and create Device-Group let failover function up… Why the peer IP show nothing? （I use LTM v10.1 VE upload again and the Peer IP is correct）
