=head1 OPTIONS
|
||||
|
||||
|
||||
B<-h |--help> Display usage message.
|
||||
|
||||
B<-v |--version> Display xCAT version.
|
||||
|
||||
|
||||
B<-n | --node> A remote host name or ip address that contains the install image to be updated.
|
||||
|
||||
|
||||
B<-p |--path> Path to the install image.
|
||||
|
||||
|
||||
=head1 RETURN VALUE
|
||||
|
||||
0 The command completed successfully.
|
||||
|
||||
1 An error has occurred.
|
||||
|
||||
=head1 EXAMPLES
|
||||
|
||||
1. To update the image on the local host.
|
||||
|
||||
I<updte_SNimage -p /install/netboot/fedora8/x86_64/test/rootimg>
|
||||
|
||||
|
||||
2. To update the image on a remote host.
|
||||
|
||||
I<updte_SNimage -n 9.112.45.6 -p /install/netboot/fedora8/x86_64/test/rootimg>
|
||||
|
||||
|
||||
=head1 FILES
|
||||
|
||||
$XCATROOT/bin/chdef
|
||||
|
||||
(The XCATROOT environment variable is set when xCAT is installed. The
|
||||
default value is "/opt/xcat".)
|
||||
|
||||
|
||||
=head1 NOTES
|
||||
|
||||
This command is part of the xCAT software product.
|
||||
When going to a remote host, the command uses scp. It is best to have ssh keys setup so you will not be prompted for a password on each copy.
