#
# COMPONENT_NAME: CSPOC Command Line Interface
#
# Name:
# cli_mkvg
#
# Description:
# Use C-SPOC to run the mkvg command with the given parameters and make the
# volume group definition known on all cluster nodes
#
# Arguments:
#
# Same as for the mkvg command; assumed validated by caller
#
# Physical volume names are assumed valid on the node this command is run
# on; C-SPOC will handle the case where the disk names are different on
# different nodes
#
# If '-n' (no autovaryon) is not supplied, it will be added
#
# Setting the environment variable _DEBUG to 1 -> 9 turns on levels of
# C-SPOC debugging
#
# Return Values:
# As set by cl_mkvg
#
# Notes:
# The '-f' flag is passed on cl_mkvg to surpress unnecessary checking. As a
# consequenc, the operation will proceed even if not all nodes are
# accessable.
