NOTES
Removing an entire host definition by issuing the removehost <hostname> command is
not equivalent to removing all of the paths associated with a host. The latter leaves a host
definition with no paths associated to it, whereas the former removes the entire host definition.
Verify the removal of hosts by issuing the showhost command.
