+# SCRIPT: stale_PP_mon.ksh
+#
+# AUTHOR: Randy Michael
+# DATE: 01/29/07
+# REV: 1.2.P
+# 
+# PLATFORM: AIX only
+#
+# PURPOSE: This shell script is used to query the system for stale PPs.
+#         The method queries the system for all of the currently vaied-on
+#         volume groups and then builds a list of the PVs to query. If a PV
+#         query detects any stale partitions notification is sent to the
+#         screen. Each step in the process has user notification
+#
+# REVISION LIST:
+#
+#
+# set -x # Uncomment to debug this shell script
+# set -n # Uncomment to check command syntax without any execution
