###############################################################################
#
#   COMPONENT_NAME: CSPOC Command Line Interface
#
# Name:
#   cli_replacepv
#
# Description:
#   Use C-SPOC to run the replacepv command with the given parameters and make the
#   volume group definition known on all cluster nodes
#
# Arguments:
#   Same as for the replacepv 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
#
#   Setting the environment variable _DEBUG to 1 -> 9 turns on levels of
#   C-SPOC debugging
#
# Return Values:
#   As set by cl_diskreplace
#
# Notes:
#   The '-f' flag is passed on cl_replacepv to surpress unnecessary checking.
#   As a consequenc, the operation will proceed even if not all nodes are
#   accessable

#   Variables needed by cl_diskreplace
#   _REFNODE - the node on which the hdisk names are chosen, since they
#           may differ across the cluster
#   _CSPOC_MODE - working with shared (as opposed to concurrent) volume
#           groups
#   _CSPOC_CALLED_FROM_SMIT - can skip checks on input

#   Construct the node list so that the local node shows up as first in the
