- -nosite
- (Optional) Resets the site value.

for at least one host in that host cluster. You do not have to specify this parameter if you
are changing site 0.
Remember: Using the force parameter might
result in a loss of access. Use it only under the direction of your product support

Description
This command changes the name, type, or a site on a host cluster object.
If you assign a host to a site and it is not specified as
site0, you must use
-force to change it.
Important: Do not specify -site
site0, instead use -nosite.
If you specify the -site and -type parameters, the
site and type properties that are changed are not attributes of the host cluster object. They
are properties of the individual hosts that are members of the host cluster. These properties
can be modified by using the chhostcluster command to change the attribute
values on every host in the host cluster simultaneously (rather than modifying each host
separately).
