unable to monitor Raid controller/logical/Disk drivers in IBMDirector5.20.3   

I have IBM Director server 5.20.3 and Server Raid Manager 9 installed. I can monitor Raid through SRM but in the IBM Director Console Inventory query results for Raid controller, Raid logical drivers, Raid Disk drivers display "There is no inventory data available for this query at this time." message as in attachment

Please let me know if i miss any thing.
--OS: Win2k3 sp2 R2-32 bit
--X236 server

Thanks a lot Graham. :) The problem is resolved after installting 'serveraid_9.00_server_windows.exe'.
I have few more questions.
But 1) using GetIf for below ODIs(mentiond few) not geting any values
2) I have one more x64 2008 environment with IBM system director 6.1. Could you let me path for plug-ins /extention for server raid.

I was trying to resolve this issue quite long time. Please help me out.
