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)
