###### mknb.8 ###### .. highlight:: perl **** NAME **** \ **mknb**\ - creates a network boot root image for node discovery and flashing ******** SYNOPSIS ******** \ **mknb**\ \ *arch*\ *********** DESCRIPTION *********** The \ **mknb**\ command is run by xCAT automatically when xCAT is installed on the management node. It creates a network boot root image (used for node discovery, BMC programming, and flashing) for the same architecture that the management node is. So you normally do not need to run the \ **mknb**\ command yourself. If you make custom changes to the network boot root image, you will need to run \ **mknb**\ again to regenerate the diskless image to include your changes. If you have an xCAT Hierarchical Cluster with Service Nodes having local /tftpboot directories (site.sharedtftp=0), you will need to copy the generated root image to each Service Node. Presently, the architectures x86_64 and ppc64 are supported. For ppc64le, use the ppc64 architecture. ******* OPTIONS ******* \ *arch*\ The hardware architecture for which to build the boot image. ************ RETURN VALUE ************ 0. The command completed successfully. 1. An error has occurred. ******** SEE ALSO ******** makedhcp(8)|makedhcp.8
