The resource definitions that you have created for the tutorial can be
removed; this allows other people to follow the tutorial, and ensures that
your CSD file space is not being used unnecessarily. Using the DELETE command,
you can delete the whole of groups AAA1 and AAA2 from your CSD file:
CEDA DELETE ALL GROUP(AAA1)
CEDA DELETE ALL GROUP(AAA2)
Note that you cannot delete the group itself;
it ceases to exist only when it contains no resource definitions. See
The CEDA DELETE command for more information on the DELETE command.
