coolingzones command

Note
If one or more fan modules in a cooling zone are missing, the components installed in that cooling zone might not cool sufficiently. Check the CMM event log for temperature event messages using the displaylog command.

If command syntax is not correctly entered, or if a command fails to run, an error message is returned. See Common errors for a list of error messages that apply to all commands or coolingzones command errors for a list of error messages that are specific to the coolingzones command.
