How to Configure Prestoserve With DiskSuite (Command Line)

The following steps describe how to load and enable Prestoserve for use with DiskSuite. Basically, you edit the /etc/system file to load Prestoserve after the DiskSuite driver.

  1. Add the following line to the /etc/system file. 


    exclude: drv/pr

  2. Edit the /etc/init.d/lvm.init file and add the following lines to the end of the "start" clause. 


    'start')
	rm -f /tmp/.mdlock
	if [ -x "$METAINIT" -a -c "$METADEV" ]; then
		#echo "$METAINIT -r"
		$METAINIT -r
		error=$?
		#echo "$error"
		case "$error" in
		0|1)	;;
 
		66)
echo "Insufficient metadevice database replicas located."
echo ""
echo "Use metadb to delete databases which are broken."
echo "Ignore any \"Read-only file system\" error messages."
echo "Reboot the system when finished to reload the metadevice
database."
echo "After reboot, repair any broken database replicas which
were deleted."
			/sbin/sulogin < /dev/console
echo "Resuming system initialization. Metadevice database will
remain stale."
			;;
 
		*)	echo "Unknown $METAINIT -r failure $error."
			;;
		esac
    modload /kernel/drv/pr
    presto -p >/dev/null
	fi
	;;

  3. Edit the /etc/init.d/prestoserve file.

    Replace the following line:


    presto -u

    with the line:


    presto -u /filesystem...

    In this command, filesystem... is a list of every file system to be accelerated with Prestoserve. Do not include any of the following:

    • root (/)

    • /usr

    • /usr/kvm

    • /var

    • /var/adm
