# DESCRIPTION:
# The Array Monitor Start/Stop Script is invoked by the system startup/
# shutdown processing.  It has three main functions:  (1) perform SNMP-
# related startup/shutdown processing (entails sending LINK UP/LINK DOWN
# traps), (2) start/stop the array monitor daemon, and (3) start/stop the
# RDAC (Redundant Disk Array Controller) daemons.  There is a single input
# argument, "start" or "stop" to indicate whether we are starting up or
# shutting down.

# PROCEDURE:	amdemon (main)
# SUMMARY:	Control SYMsm startup/shutdown operations
#
# DESCRIPTION:
# Below is the amdemon main procedure which implements the start/stop
# commands SYMsm startup and shutdown.  As described above, startup
# issues a LINK UP trap and launches the SYMsm daemons and shutdown
# issues a LINK DOWN trap and stops the SYMsm daemons.
#
# SYNTAX:
# amdemon <action>
# <action> = start | stop
# start -> initialize SNMP and daemons for SYMsm
# stop -> "close" SNMP link and stop SYMsm daemons
#
# NOTES:
#
# RETURNS:
# Nothing
