Example 5-42 CEC node in xCAT database
# lsdef f15cec01
Object name: f15cec01
groups=cec,all,f15cec
hcp=f15cec01
hidden=0
hwtype=cec
id=3
mgt=fsp
mtm=9125-F2C
nodetype=ppc
parent=frame15
postbootscripts=otherpkgs
postscripts=syslog,aixremoteshell,syncfiles
serial=02C4DB6
sfp=c250hmc21
supernode=2,0
Example 5-42 includes the following attributes:
hcp: The hardware control point for this CEC. For DFM, the HCP always is set to itself.
id: The cage number of this CEC in a 24-inch frame.
mgt: This attribute is set to fsp.
mtm: Indicates the machine type and model.
parent: The frame node in which this CEC is located.
serial: The serial number of the CEC.
sfp: The HMC that is connected to this CEC for collecting hardware-serviceable events.
supernode: The HFI network supernode number of which this CEC is a part. For more
information about the value to which this number must be set, see the Power Systems High
performance clustering using the 9125-F2C Planning and Installation Guide, at this website:

Important: In addition to setting the CEC supernode numbers, set the HFI switch topology
value in the xCAT site table. For more information about the value to which this number
must be set, see the Power Systems High performance clustering using the 9125-F2C
Planning and Installation Guide, at this website:

FSP node
FSP node is a node with the hwtype set to fsp and represents one port on the FSP. In one
CEC with redundant FSPs, there are two FSPs and each FSP has two ports. There are four
FSP nodes that are defined by xCAT per server with redundant FSPs. Similar to the
relationship between Frame node and BPA node, the system administrator always uses the
CEC node for the hardware control commands. xCAT automatically uses the four FSP node
definitions and their attributes for hardware connections, as shown in Example 5-43 on
page 292.
