In the latest code, xCAT does not support to set the query interval for the get next destiny (task).
If you set the runcmd=bmcsetup, the node will try to run the getdestiny to communicate with xcatd to get the next destiny every 5 seconds. If you set the standby as the next destiny, it will sleep 15-30 seconds and try to get again. So the question, what do you want the node to do after running of bmcsetup? If nothing to do, keep it to 'shell' is a good idea. BTW, I am wondering that which perl process used 100% CPU resource?
