=head1 groupfiles4dsh
This tool will build a directory of files for each defined
nodegroup in xCAT. The file will be named the nodegroup name and
contain a list of nodes that belong to the nodegroup.
The file can be used as input to the AIX dsh command run in the DSH
context.
The purpose of this tool is to allow backward compatiblity with scripts
that were created using the AIX or CSM dsh command.
groupfiles4dsh -p <directory to place generated nodegroup files>
example: groupfiles4dsh -p /tmp/dshnodegrpfiles
Use: export DSH_CONTEXT=DSH ( default unless CSM is installed)
export DSH_NODE_RSH=/bin/ssh (default is rsh)
export DSH_NODEGROUP_PATH= /tmp/dshnodegrpfiles
dsh -N all date ( all is a group in xCAT)
dsh -a date ( see man dsh, DSH context)
