Unable to run crsctl check with crs parameter

I'm trying to install Grid Control 11.2 on Linux 5, but have hit some problems for which I have raised a SR with Oracle.  However I have been asked to run crsctl check crs, but whenever I try this I get:

[root@rugrat bin]# ./crsctl check crs
Parse error:
  'crs' is an invalid argument

Brief usage:
  crsctl check has
     Check status of OHAS

  crsctl check resource {<resName> [...]|-w <filter>} [-n <server>] [-k <cid>] [-d <did>]
     Check status of resource(s)

  crsctl check css
     Check status of Cluster Synchronization Services

For complete usage, use:
    crsctl [-h | --help]
For detailed help on each command and object and its options use:
