Used on hosts with Solaris Disksuite volume management. The script parses metastat output and checks the status of metadevices. Any errors are collated and a status report is emailed.

# Quickie script to catch Disksuite breakage
#
# We store a temp file in /tmp with our errors - once the script is complete, if
# that file has anything in it we know something has gone wrong - so we 
# email it off

# Some vars
PATH=/usr/sbin:/usr/opt/SUNWmd/sbin:/usr/bin
# Odd path is easier than trying to work out where ODS tools have been
# hidden in this OE release :-)
HOSTNAME=`uname -n`
# Who do we want to know about breakage?
SYSADMINS=<email_address_here>

# Setup our temp file
OUTPUT=/tmp/ods_breakage.txt

# We don't want any old rubbish lying around
if [ -f $OUTPUT ]
then
	rm $OUTPUT
fi

# Let's check to see if we actually have ODS, shall we?
if [ -z  "`pkginfo | grep SUNWmdg`" ]
then
	# If we silently bail, we can just roll this out across an
	# estate as part of a standard toolkit
	# Easier to support a common toolset installed on all machines
	# than lots of local machine customisations
	exit 1
fi

# Get metastat to list our mirrors
MIRRORS=`metastat | grep Mirror | cut -d: -f1`

# Cycle through the mirrors, looking for breakage
# Feel free to add extra if loops looking for specific issues
for MIRROR in $MIRRORS 
do
	if [ "`metastat $MIRROR | grep \"Needs maintenance\"`" != "" ]
	then
		echo "" >> $OUTPUT
		echo "WARNING:" >> $OUTPUT
