It also lists the physical port withineach FSP, which is determined by the IP address order from the lsslp response. Thisinformation is used internally when communicating with the FSPs. parent: Set to the CEC in which this FSP is located. mac: The mac address of the FSP, which is retrieved from lsslp. hidden: Set to 1 means that xCAT hides the node by default in nodels and lsdef output.FSP nodes are hidden because you use only the CEC nodes for management. To see theFSP nodes in the nodels or lsdef output, use the -S flag.LPAR types of nodesThere are four types of nodes in a Power 755 cluster: Service nodeThis is an LPAR node that helps the hierarchical management of xCAT by extending thecapabilities of the EMS. The service node features a full disk image and is used to servethe diskless OS images for the nodes that it manages, as shown in Example 5-44.Example 5-44 The NIM OS image in a service node# lsnim | grep GOLD_71BdsklsGOLD_71Bdskls resources spotGOLD_71Bdskls_dump resources dumpGOLD_71Bdskls_paging resources pagingGOLD_71Bdskls_shared_root resources shared_rootGOLD_71Bdskls_resolv_conf resources resolv_confDFM: For the Power 755 cluster, we use DFM to communicate directly to the PowerSystems server's service processor without the use of the HMC for management. |
