Find out why the channel is down and then start it back up?

Check the properties of the channels ( cluster sender and cluster receiver )
They should be in UP state..if all is fine in the cluster. They used to come up automatically. If they are not then something is wrong and xmitq will have msgs on it. START the channel (cluster sender) after checking the channel properties. All should be fine.
Make sure the queues are able to accept the msgs that you are sending.

When the qmgrs are in cluster make sure the cluster channels NOT in retrying state. Check the msgs on the SCTQ where they are destined for. You can look into the CorrelId of the msgs on SCTQ which shows the destination channel and you can find the destination qmgr where the msgs are destined for. Make sure the destination qmgr is up and running and accepting the msgs.

Thanks.

There is no UP state. Channels must be in RUNNING state in order to transmit messages.

Cluster channels start automatically - unless there are errors. Take a look in the error logs.

Do a DISPLAY CHSTATUS(*) to see which channels are not RUNNING - look for RETRYING or some other non-STOPPED state. DIS CLUSQMGR(*) will yield similar information.

I know that... I meant to say It should be in UP and RUNNING mode... Ofcourse the RUN State

I knew that you knew that. But newbies might take your UP literally, and believe if the channel status doesn't say UP that it is a bad thing.

Endlessly struggling for clarity.
