=head1 B<Description>
|
||
|
|
|
||
|
|
B<psh> is a utility used to run a command across a list of nodes in parallel.
|
||
|
|
|
||
|
|
B<ssh> must be set up to allow no prompting for B<psh> to work.
|
||
|
|
|
||
|
|
Note: this command does not support the xcatd client/server communication and therefore must be run on the management node.
