execute_dcp
|
|
|
|
This is the main driver routine for an instance of the dcp command.
|
|
Given the options configured in the $options hash table, the routine
|
|
configures the execution of the dcp instance, executes the remote copy
|
|
commands and processes the output from each target.
|
|
|
|
Arguments:
|
|
$options - options hash table describing dcp configuration options
|
|
|
|
Returns:
|
|
The number of targets that failed to execute a remote copy command
|
|

resolve_nodes.
|
|
|
|
Arguments:
|
|
$options - options hash table describing dsh configuration options
|
|
$resolved_targets - hash table of resolved targets and target properties
