Cluster management (xCAT tool):

Example: <noderange> = compute001-compute005

Display node status (from xcat01):
# nodestat <noderange>

Reinstall node (from xcat01):
# rinstall <noderange>

Update nodes with xcat01 master configuration:
# updatenode <noderange>

Node power control (from xcat01):
# rpower <noderange> [on|onstandby|off|suspend|reset|stat|state|boot]

Run commands in parallel on all nodes:
# xdsh <noderange> command

Check Infiniband interface (from any node):
# ibstat
