The manual states that "...Before you restart a failed queue manager, you must disconnect your applications from that instance of the queue manager. If you do not, the queue manager might not restart correctly...", so did you? Anything in the queue manager error logs or general error logs?

Are there any error messages, in the qmgr error logs, or in /var/mqm/errors ? |

That'll be <MQ_FILE_PATH>\errors as it's Windows

the error log is:
Process(2204.1) User(mq_user) Program(amqzxma0.exe) Host(FIRSTNODE)
AMQ6184: An internal WebSphere MQ error has occurred on queue manager test101.
EXPLANATION:
An error has been detected, and the WebSphere MQ error recording routine has
been called. The failing process is process 2204.
ACTION:
Use the standard facilities supplied with your system to record the problem
identifier and to save any generated output files. |

Were you able to identify what PID 2204 was? It being Windows, and a test environment, I'd reboot both nodes, ensure no applications are running against the queue manager, snapshot the running processes, and retest the fail-over. If it fails again then it should be easier to identify the issue, or reboot again and switch on trace. I'm assuming the Windows Sys Admins don't mind their DCs being bounced!

| Could slow server connections cause this problem? when I use two windows servers and use one of them to hold shared directories, if the stand by server run on the machine which holding shared data, switch over takes place but when I use 3 windows servers and shared directories reside in a separate machine from servers running MQ, switch over doesn't take place at all and I receive the error mentioned at previous post. |

It's possible, time-outs etc. But your Sys Admins and network people should be able to identify if that's a factor.

Open a PMR for this. There should be FDC files in MQMDIR\errors that you can supply to IBM. |
