WebSphere MQ support for MSCS includes the following utility programs that you can run at a command prompt:
After you unregister the WebSphere MQ MSCS resource type you can no longer create any resources of that type. MSCS does not let you unregister a resource type if you still have instances of that type within the cluster:
haregtyp /u
If you want to register the type (or re-register it at a later time), enter the following command at a command prompt:
haregtyp /r
Consider the case where you have had a queue manager in your cluster, it has been moved from one node to another, and now you want to destroy it. Use the WebSphere MQ Explorer to delete it on the node where it currently is. The registry entries for it still exist on the other computer. To delete these, enter the following command at a prompt on that computer:
hadltmqm /m qmname
where qmname is the name of the queue manager to remove.
This utility presents a dialog showing full details of your WebSphere MQ MSCS Support setup, such as might be requested if you call IBM support. There is an option to save the details to a file.
