3ware Install and Configure

Some of these steps may be specific to the NRAO.

---

Setup System

• Add a fixed address for aoc-oss-X in the 10.64.1.XXX range. Use next available low order address.
• If the machine was purchased by someone else make a CNAME. e.g. cfa-oss-1, caltech-oss-1.
• Add dhcp entry with a fixed address line.
• Remove existing raid volumes from within 3ware interface (alt-3) at boot time. There are multiple controllers remove from all.
• Install RHEL5.7 64bit release, use the existing aoc-oss-1 kickstart as a template.
  • Should result in OS disk with / root directory, swap and rest in /export/home/`hostname`

• [ ! -d /export/home/`hostname`/services ] && mkdir -p /export/home/`hostname`/services

• ln -s /export/home/`hostname`/services /opt/services

Install RAID Software

Download the 3DM2 CLI Linux non-java installer (3ware9650SE-8LPML) from http://www.lsi.com/

Make an install area

mkdir -p /tmp/root
cd /tmp/root

Open tarball (NRAO keeps a local copy)

tar xfvz /home/src/3dm2/3dm2-CLI-non-java-linux-9.5.3.tgz

Run the installer

./install.sh -i -fN0

Install in /opt/services

mv /opt/3ware /opt/services/3ware
rm -f /usr/sbin/3dm2 && ln -s  /opt/services/3ware/3DM2/3dm2 /usr/sbin/3dm2
sed -i -e 's|/opt/3ware|/opt/services/3ware|g' /etc/3dm2/3dm2.conf

Configure (NRAO/AOC specific)

sed -ie 's/^Port 888/Port 443/' /etc/3dm2/3dm2.conf
sed -ie 's/^EmailEnable .*$/EmailEnable 1/' /etc/3dm2/3dm2.conf
sed -ie 's/^EmailSender .*$/EmailSender root@aoc.nrao.edu/' /etc/3dm2/3dm2.conf
