Appendix B.  Superdome Virtual Partitions


To assign the components that will be assigned to the vPars within an nPartition, you must run ioscan in the nPartition in which the vPars will be created. This provides a list of all I/O components, CPUs, and so on, available in the nPartition to be used in the vPars. The ioscan does not show components in the other nPartitions. The following full ioscan listing shows all the components in the nPartition in which we'll create our four vPars:

Note that the cell itself, which is for all intents and purposes a separate server, is at address 5. There are four processors, shown at the end of the listing, at 5/10, 5/11, 5/12, and 5/13. We're going to assign many of the I/O components in this listing to our four vPars, so you may end up referring back to the diagram.
