[Sunhelp] Sorry, a few Sun novice questions

[David Watson]

Assuming that you have the server license for Solaris, it should have come
with a CD-ROM containing Sun Disksuite. This is a software RAID
implmentation. You don`t need to do anything with the disks until after you
have installed Solaris, which seems a little counter intuitive to NT RAID
users!

Take a look this for more info:

http://docs.sun.com:80/ab2/@LegacyTocView?toc=SUNWab_68_1%3A%2Fsafedir%2Fspa
ce3%2Fpkgs%2Fcollections%2Fab1%2FSUNWabmd%2Ftoc%2FDISKSUITEADMIN%3ADISKSUITE
ADMIN;bt=Solstice+DiskSuite+4.0+Administration+Guide

I`ve used the following shell script as part of an automated disksuite
install under Jumpstart, if you want to just jump straight in. Apoligies to
any code purists: ;-)

#!/bin/sh
#
# Install and configure Solstice Disksuite
# WARNING - Only run this script if you understand it!
# WARNING - You will probably trash your disks...
#
# This configuration will create a two disk stripe for performance and
mount it on /projects
#
echo
echo "Installing Solstice Disksuite 4.0..."

tar xvf /opt/src/core/disksuite.tar
pkgadd -d . all << EOF

mkdir /projects
mount /dev/md/dsk/d0 /projects/
cd /opt
rm -rf tmp
echo "Done."

Hope that helps,

David
