remote_copy_command
|
|
|
|
This routine constructs an rsync remote copy command using the
|
|
given arguments
|
|
|
|
Arguments:
|
|
$class - Calling module name (discarded)
|
|
$config - Reference to copy command configuration hash table
|
|
$exec_path - Path to rsync executable
|
|
$localhost - 1 indicates we are running on the Management Node
|
|
|
|
Returns:
|
|
A command array for the rsync command with the appropriate
|
|
arguments as defined in the $config hash table
|
|
|
|
Globals:
|
|
None
|
|
|
|
Error:
|
|
None
|
|
|
|
Example:
|
|
xCAT::RSYNC->remote_copy_command($config_hash, '/usr/bin/rsync');
|
|
|
|
Comments:
|
|
$config hash table contents:
|
|
|
|
$config{'dest-file'} - path to file on destination host
|
|
$config{'dest-host'} - destination hostname where file will be copied
|
|
$config{'dest-user'} - user ID of destination host
|
|
$config{'options'} - custom options string to include in scp command
|
|
$config{'preserve'} - configure the preserve attributes on scp command
|
|
$config{'recursive'} - configure the recursive option on scp command
|
|
$config{'src-file'} - path to file on source host
|
|
$config{'src-host'} - hostname where source file is located
|
|
$config{'src-user'} - user ID of source host
