getslnodes.py was using argparse, which is not included on centos6.5
and not available in python 2.6... switched to using docopt for command line interface argument parsing. This python library is pulled in by the SoftLayer python bindings so it's not an extra step.

# Query the softlayer account for info about all of the bare metal servers and

# put the info in mkdef stanza format, so the node can be defined in the xcat db

"""
|

Usage: getslnodes.py [-h] [-v] [<hostname-match>]
|
||||
|
||||
Description:
|
||||
Query your SoftLayer account and get attributes for each bare metal server.
|
||||
The attributes can be piped to 'mkdef -z' to define the nodes into the xCAT
|
||||
Database so that xCAT can manage them.
|
||||
|
||||
getslnodes requires a the .softlayer configuration file defined which can
|
||||
be set by running "sl config setup" on the command line.
|
||||
|
||||
positional arguments:
|
||||
hostname-match Select servers that include this partial hostname.
|
||||
|
||||
Optional:
|
||||
-h, --help show this help message and exit
|
||||
-v, --verbose display verbose output
