## NAME:	cl_db2mt_import
##
## DESCRIPTION:	Runs cl_db2import twice for mutual takeover.
##		Accepts the same set of arguments as cl_db2import, but
##		accepts a second set of arguments for the second instance
##
## ARGUMENTS:
##	 -A Application Name
##
##	 -a Add/change all necessary HACMP resources for the specified DB2
##	    instance.  If the resources already exist, they will be removed
##		and then added.  This is the change/modify mode.
##
##	 -r Remove all HACMP resources for the specified DB2 instance.
##		
##	 -N DB2 UDB first node.
##
##	 -n DB2 UDB second node(s). 
##
##	 -I and -i DB2 UDB instance name to be made highly available or removed.
##	    This is the only option required when removing (-r) the resources.
##
##	 -D and	-d DB2 UDB database name.  This database is used by the Custom
##		SQL Monitor.
##
##	 -I and	-l The TCP/IP service IP label used by DB2 to communicate with
##		other application tiers and/or clients.
##
##	 -M Delete the pre-existing configuration (change/show mode)
##
## RETURN:
##	0       Success (import completed without error)
##	1       Warning (import completed with warning(s))
##	2       Failure (import failed due to pre-verification failure)
##	3       Failure (import failed due to failure in adding resource)
