Sorry I misread your post. You've already installed MSCS.

Got this from metalink. This might help.

Did you recieve any errors during your Failsafe installation? Did the Fail Safe service create? Are you recieving this error after your initial installation or was Fail Safe working previously? Did you install Oracle Fail Safe Server on ALL cluster nodes sequentially, one node at a time? Did you reboot after your first installation of Fail Safe into a new Oracle home on the cluster node? Did you verify that Oracle Fail Safe Is in the Cluster Group? You will want to make sure that you have successfully performed all of the pre-installation tasks and installation procedures as documented within the Oracle Fail Safe Installation Guide.
