HI,
I am trying to remove a Partial repos qmgr from the cluster.
i have removed the q's from the cluster .
Removed the clussdr and clusrcvr channels from the cluster.

now when i issue
dis clusqmgr(qmgrname) its not showing any details.
but when i issue
dis clusqmgr(*) its showing details of the full repos channels and other PR qmgr details.

also dis qc(*) is showing objects from other PR qmgrs.

All the clussdr and clusrcvr channels are in stopped state.

On the FR qmgr also the channels are removed from cluster.

This is something i see with dis clusqmgr(*)
the clusqmgr shown here is not the local qmgr.

CLUSQMGR(CMAS) CHANNEL(TO.CMAS)
CLUSTER(S.CMCC.EXL)
AMQ8441I: Display Cluster Queue Manager details.
CLUSQMGR(CMAS) CHANNEL(TO.CMAS)
CLUSTER(S.CMCC.BAT)

Somehow i see the put and get dates update on the system.cluster.command.queue

dis qs(SYSTEM.CLUSTER.COMMAND.QUEUE)
AMQ8450I: Display queue status details.
QUEUE(SYSTEM.CLUSTER.COMMAND.QUEUE) TYPE(QUEUE)

dis qs(SYSTEM.CLUSTER.COMMAND.QUEUE) type(handle) all

TID(1)
URID(XA_FORMATID[] XA_GTRID[] XA_BQUAL[])

Did i miss anything while removing the qmgr from the cluster or is this behaviour normal ?

There is a specific procedure to follow:
    * remove any cluster attributes from all the clustered queues
    * stop the cluster sender/receiver and remove it's cluster attribute
    * restart the cluster sender/receiver
    * verify on one of the FRs that the qmgr is no longer part of the cluster
    * and if the qmgr was part of a uniform cluster you first need to remove it from the uniform cluster (see qm.ini) before you can remove it from the cluster.

Have fun
