B.2.3 Warning Conventions
A Warning nnnn: message means that the command completed, but there is
a situation that you should be aware of. Typically, but not always, a warning
will result in an unusable configuration; you will have to either logically
reconfigure the cabinet using the CLI or physically reconfigure the cabinet by
moving the disks around.
Multiple warning messages may result from one command.
Items in angle brackets (<>) are replaced at run time with names, numbers,
and so on.
B.2.4 CLI Warning Messages

cache in the user guide.
