my control is a 3ware 12 port control 9500s
and it worked perfect with the cli package 3DM2-CLI-Linux-X86-9.5.1.1.tgz
okay time to install on centos 5.3
log in as root
cd /tmp
wget http://www.3ware.com/download/Escalade9690SA-Series/9.5.1.1/3DM2_CLI-Linux-x86-9.5.1.1.tgz
wget http://www.sra.net.au/3dm2
tar -zxvf 3DM2_CLI-Linux-x86-9.5.1.1.tgz
./setupLinux_x86.bin -console
follow through the installer accept all defaults
mv 3dm2 /etc/init.d
chmod 755 /etc/init.d/3dm2
now let us see if it is running, this should show you it has a PID
/etc/init.d/3dm2 status
now lets set 3dm2 to start on boot
chkconfig --levels 2345 3dm2 on
now it is time to log in to the web interface
user=admin password=3ware
