#@ Reason : Set default return status to Unknown
#@---------------------------------------------------
#@ Date : 20100702
#@ Author : Aaron Rogers www.cloudmark.com
#@ Reason : GlobalStatus was incorrectly getting (re)set to OK with every CIM element check
#@---------------------------------------------------
#@ Date : 20100705
#@ Author : Claudio Kuenzler www.claudiokuenzler.com
#@ Reason : Due to change 20100702 all Dell servers would return UNKNOWN instead of OK...

#@---------------------------------------------------
#@ Date : 20101028
#@ Author : Claudio Kuenzler www.claudiokuenzler.com

#@ Author : Phil Randal
#@ Reason : URLise Dell model and tag numbers (as in check_openmanage)

#@---------------------------------------------------
#@ Date : 20110505
#@ Author : Phil Randal (phil.randal@gmail.com)
#@ Reason : Simplfy 'verboseoutput' to use 'verbose' as global variable instead of as parameter
