| 
 | |
|  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)
