To avoid any ambiguity, it is preferable to use QMID rather than QMNAME.
The queue manager identifier can be found by commands such as DISPLAY QMGR
and DISPLAY CLUSQMGR.
If QMNAME is used, and there is more than one queue
manager in the cluster with that name, the command is not actioned.
If you use characters other than those listed
in Rules for naming WebSphere MQ objects in your object or variable names, for example in
QMID, you must enclose the name in quotes.
If you remove a queue manager from
a cluster using this command, you can rejoin it to the cluster by issuing
a REFRESH CLUSTER command. Wait at least 10 seconds before issuing a REFRESH
CLUSTER command, because the repository ignores any attempt to rejoin the
cluster within 10 seconds of a RESET CLUSTER command.
