mknb.8

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

  1. The command completed successfully.

  2. An error has occurred.
