=head1 NAME
|
|
|
|
B<mknb> - creates a network boot root image for node discovery and flashing
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<mknb> I<arch>
|
|
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The B<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
|
|
B<mknb> command yourself.
|
|
|
|
If you make custom changes to the network boot root image, you will need to run B<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.
