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 mknbcommand yourself.

If you do run mknb to add custom utilities to your boot root image, and you have an xCAT Hierarchical Cluster with service nodes that each have a local /tftpboot directory (site sharedtftp=0), you will also need to copy the generated root image to each service node.

Presently, only the arch x86_64 is supported.

OPTIONS

arch

The hardware architecture for which to build the boot image: x86_64

RETURN VALUE

0 The command completed successfully.

1 An error has occurred.
