Chapter 5. Maintenance and serviceability 291Example 5-42 CEC node in xCAT database# lsdef f15cec01Object name: f15cec01groups=cec,all,f15cechcp=f15cec01hidden=0hwtype=cecid=3mgt=fspmtm=9125-F2Cnodetype=ppcparent=frame15postbootscripts=otherpkgspostscripts=syslog,aixremoteshell,syncfilesserial=02C4DB6sfp=c250hmc21supernode=2,0Example 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 moreinformation about the value to which this number must be set, see the Power Systems Highperformance clustering using the 9125-F2C Planning and Installation Guide, at this website:http://www.ibm.com/developerworks/wikis/display/hpccentral/IBM+HPC+Clustering+with+Power+775+Recommended+Installation+Sequence+-+Version+1.0#IBMHPCClusteringwithPower775RecommendedInstallationSequence-Version1.0-ISNMInstallationFSP nodeFSP node is a node with the hwtype set to fsp and represents one port on the FSP. In oneCEC with redundant FSPs, there are two FSPs and each FSP has two ports. There are fourFSP nodes that are defined by xCAT per server with redundant FSPs. Similar to therelationship between Frame node and BPA node, the system administrator always uses theCEC node for the hardware control commands. xCAT automatically uses the four FSP nodedefinitions and their attributes for hardware connections, as shown in Example 5-43 onpage 292.Important: In addition to setting the CEC supernode numbers, set the HFI switch topologyvalue in the xCAT site table.
