Checkpoint my notes on setting up the control node. Eventually this

will become a wiki page ...

Setting up the control node:
Need the following info:
1. Hostname for the control node.
2. IP and netmask for the control node.
3. IP for the ilo interface on the control node (same netmask).
4. IP for your DNS server.
5. IP for your default router.
* Send Utah all of the above info so that we can "bake" an image
for you. Once you hear back from us, you may continue with these
Waiting, waiting, waiting ...
* Power on the control switch (Procurve 2610 in the top slot).
* Attach a console to the control node and power on the node. You will
wait a while for the "HP ProLiant" screen. Wait until it says "press
any key for Option ROM messages" and then right after the screen
switches, type F8 to get into the iLo configuration. Gotta be fast
on this. If you miss it, power cycle.
* Once the iLo screen comes up, right arrow to Network and choose the
DHCP option. You want to make sure DHCP is off. F10 to save and then
esc to go back. Then choose the NIC option. Fill in the iLo
IP/Mask/Router, then F10 to save and then esc to exit. iLo will
* At this point you can go back to your desk and work from there.
* Using your web browser, go to the iLo IP you set, and login using
Administrator and the iLo password that is stamped on top of the
control node, or in the data file you received.
* Click on the Remote Console tab, and then on remote console. Click
on the java launch button. Wait for the popup boxes that ask you
to trust it. Say yes of course, and wait for the console window to
* Go to the Virtual Media tab, and then on the right hand side specify
the url of the boot ISO image. This will be something like:
which is Utah's web server. Check the box to boot from the CD on the
next reset, and then click the reset button.
* Wait for the node to boot. It should boot from the virtual CD drive
since there is no other boot media, but if not you can hit F11 on
the next go around, which will give you a list of options. Type
whatever number is to the left of the CD choice.
* The ISO will load and give you a boot prompt. Just hit return. You
will evntually get a shell prompt after a lot of noisy output.
* Fire up the network:
ifconfig eth0 inet Control_IP netmask Control_Mask
route add default gw Gateway_IP
The Control_IP is *NOT* the iLo IP you used above. It is the IP you
have assigned to the control node itself.
* Transfer the control node image from Utah:
cd /tmp
This is about a 1GB so it will take a while.
* Write the image file to the disk using Emulab decompression tool:
/usr/bin/imageunzip -o genirack.ndz /dev/cciss/c0d0
This will take a little while.
* Set the boot order so that the control node does not try to boot
from the network, unless all else fails.
./setbootorder floppy cdrom usb hd pxe
* Type "reboot" at the shell prompt. With any luck, the node will boot
first time.
* At this point we need to configure the switches with static IP
addresses. This is a bit tricky since the only way to do this is to
have DHCP return a dynamic address so we can telnet to the switch
long enough to change its address. Yes, this is a pain but we cannot
have multiple DHCP servers running since that would confuse boss.
Login to the control node as root.
/usr/sbin/dhcpd -4 -cf /etc/dhcp/dhcpd.conf xenbr1 xenbr2
Now power on the experimental switch, and power cycle the control
switch so that it will restart its dhcp cycle. You will lose
connectivity to the control node for a moment or two.
Once you get connectivity back, tail the end of the /var/log/syslog to
see if the switches have made their DHCP requests.
* At some point you will be able to telnet to and
These are the IPs assigned by dhcp.
First telnet to This is the control switch (2610). You want
to issue the following commands at the prompt.
2610> config
2610(config)> vlan 1 ip address
2610(config)> ip default-gateway
2610(config)> vlan 1 ip igmp
2610(config)> vlan 1 ip igmp querier
2610(config)> no web-management
2610(config)> password all (type in same password for manager/operator)
2610(config)> no snmp-server community public
2610(config)> snmp-server community XXXXX manager unrestricted
2610(config)> write memory
2610(config)> reload
The switch will take moment to reset so you might lose your connection
to the control node.
* Now telnet to This is the experimental switch.
5400> config
5400(config)> vlan 1 ip address
5400(config)> ip default-gateway
5400(config)> no web-management
5400(config)> password all (type in same password for manager/operator)
5400(config)> no snmp-server community public
5400(config)> snmp-server community XXXXX manager unrestricted
5400(config)> write memory
5400(config)> reload
* The 5400 will take longer to reset. Be sure you can telnet back to the
both switches and login with the password you used above. Once you are
sure that is the case, kill off dhcpd on the control node.
sudo killall dhcpd
Make sure it died by doing:
ps auxwww | grep dhcpd
* Initialize the LVM partition. We use LVMs for the boss/ops filesystems.
