 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)
