How to rename a cluster resource without stopping it

Environment

SUSE Linux Enterprise High Availability Extension 12
SUSE Linux Enterprise High Availability Extension 11

Situation

When renaming a resource in maintenance mode, it is observed the resource gets stopped under its old name and started under the new one.

Assuming there is a resource called dummy4 which should get renamed to dummy5, the following is reported by lrmd in /var/log/messages:

2017-02-24T11:32:12.984522+01:00 sles12cluster2 root: Dummy2 start
2017-02-24T11:32:12.985718+01:00 sles12cluster2 lrmd[2291]:   notice: finished - rsc:dummy5 action:start call_id:36 pid:2669 exit-code:0 exec-time:27ms queue-time:0ms
2017-02-24T11:32:12.987163+01:00 sles12cluster2 root: Dummy2 stop
2017-02-24T11:32:12.987988+01:00 sles12cluster2 lrmd[2291]:   notice: finished - rsc:dummy4 action:stop call_id:37 pid:2670 exit-code:0 exec-time:27ms queue-time:1ms

The desired behavior is to rename the resource without having a stop/start operation.

Resolution

The following steps will allow to rename a given resource without having the cluster to start/stop it:

crm configure property maintenance-mode=true
crm edit
<now apply desired changes to the cib>
crm resource reprobe
crm resource cleanup
crm configure property maintenance-mode=false

Additional Information
