Clearing UNKNOWN status of CRS resources

If you get the following errors whilst starting up nodeapps on a 10G RAC cluster

bart-> srvctl start nodeapps -n bart
CRS-1028: Dependency analysis failed because of:
CRS-0223: Resource 'ora.bart.gsd' has placement error.
CRS-1028: Dependency analysis failed because of:
CRS-0223: Resource 'ora.bart.ons' has placement error.

Check the status of these resources.

bart-> ./ShowCRS | grep UNK
ora.bart.gsd ONLINE UNKNOWN on bart
ora.bart.ons ONLINE UNKNOWN on bart

To clear the state of the resource you have to use the force option
in the crs_stop command

bart-> crs_stop ora.bart.gsd -f
Attempting to stop `ora.bart.gsd` on member `bart`
Stop of `ora.bart.gsd` on member `bart` succeeded.

bart-> crs_stop ora.bart.ons -f
Attempting to stop `ora.bart.ons` on member `bart`
Stop of `ora.bart.ons` on member `bart` succeeded.

bart-> srvctl start nodeapps -n bart
bart-> ./ShowCRS | grep UNK

bart-> ./ShowCRS | grep bart
ora.bart.gsd ONLINE ONLINE on bart
ora.bart.ons ONLINE ONLINE on bart
ora.bart.vip ONLINE ONLINE on bart
