Displaying OS host name in OM Enterprise on 11G servers

Dear All,

We have a bunch of 11G modular servers like m710s and m610s, and even though the  "Operating System Information" (hostname and OS version) fields are filled out on their iDRACs, it is not recognized/displayed in Open Manage Enterprise after discovering these servers. Other fields like CPU and Service Tag are displayed though without problem. I checked and the idrac firmware version is newer than 3.65 which is required for 11G servers.

Anyone has an idea how can we fix this? Thanks
