Example 5-43 FSP node in xCAT database
# lsdef -S 40.14.1.1
Object name: 40.14.1.1
groups=fsp,all,f14fsp
hcp=40.14.1.1
hidden=1
hwtype=fsp
id=3
ip=40.14.1.1
mac=00215ee990dc
mgt=fsp
mtm=9125-F2C
nodetype=ppc
parent=f14cec01
postbootscripts=otherpkgs
postscripts=syslog,aixremoteshell,syncfiles
serial=02C5096
side=A-0
Example 5-43 shows the following attribute meanings:
side - <FSP>-<port>: The side attribute refers to the FSP (A or B) that is determined by
the slot value that is returned from lsslp command. It also lists the physical port within
each FSP, which is determined by the IP address order from the lsslp response. This
information 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 the
FSP nodes in the nodels or lsdef output, use the -S flag.
DFM: For the Power 755 cluster, we use DFM to communicate directly to the Power
Systems server's service processor without the use of the HMC for management.
LPAR types of nodes
There are four types of nodes in a Power 755 cluster:
Service node
This is an LPAR node that helps the hierarchical management of xCAT by extending the
capabilities of the EMS. The service node features a full disk image and is used to serve
the diskless OS images for the nodes that it manages, as shown in Example 5-44.
