Bare Metal EASY Install

=====================

1) Network setup of UCS-D and BMA

  UCS-D Front: 172.17.32.155 (VM Network)

  UCS-D Back: 192.168.66.2 (VM Provision Net)

  BMA Front 192.168.66.3 (Vm Provision Net)

2) Cleaning instructions If there is a previous BMA setup on UCS-D

  Step 1) Enable root access on UCS Director (Option 22)

  Step 2) Login as root (Option 23)

  Step 3) Execute "sudo /opt/scripts/dbCNSAClean.sh” !!! Warning, this will delete all entries for any BMA servers you have !!

3) Import the BMA and IP in vCenter

4) ssh to the BMA (root/pxeboot) (Use UCS-D as jump server to get to BMA)

5) Setup dhcp

  cd /etc

  cat dhcpd.conf

  cp dhcpd.conf.sample dhcpd.conf

  vi dhcpd.conf  (fix up for your env)

  Example:

  2 lines are missing here….they are in the sample

  subnet 192.168.66.0  netmask 255.255.255.0 {

          option routers                  192.168.66.1;

          option subnet-mask              255.255.255.0;

          option nis-domain               "ciscodemo.local";

          option domain-name              "ciscodemo.local";

          option domain-name-servers      192.168.66.1;

          option time-offset              -18000; # Eastern Standard Time

          range dynamic-bootp 192.168.66.160 192.168.66.254;

          default-lease-time 21600;

          max-lease-time 43200;

          allow booting;

          allow bootp;

          next-server 192.168.66.3; # IP of my PXE server

          filename "/pxelinux.0";

  }

  /etc/init.d/dhcpd restart

6) Set up BMA -> UCSD

  ping 192.168.66.2 (ping the UCSD)

  cd /opt/infra

  ./stopInfraAll.sh

  ./configure.sh 192.168.66.2 (IP of UCSD) (Multi node this is the IP of the Inventory DB)

  ./startInfraAll.sh

7) Enable UCSD -> BMA

  ssh shelladmin@172.17.32.155 (UCSD) (changeme)

  16) Enable Database for BMA (enter IP of BMA (192.168.66.3))

  on multi node this needs to be enabled and configured on the Inventory DB server!

8) BMA

  cd /opt/infra

  ./stopInfraAll.sh

  ./startInfraAll.sh

9) Check UCSD

  administration -> Physical Accounts -> Network Services Agents

10) UCS-D (ASCII shell prompt)

  17) Add BMA Hostname/IP

  192.168.66.3 BMA

11) BMA

  vi /etc/hosts

  192.168.66.3 BMA

  192.168.66.2 UCSD

12) Update (BMA)

  vi /opt/infra/networkServices/run.sh with proper PXE and MGT IP's

  Make sure this is between -Dpxe.tftpd.enable=on and -cp

  -DpxeServer.ip=192.168.66.3 -DpxeServer.mgmt_vlan_ip=192.168.66.3

13) start httpd (BMA)

  service httpd start

  chkconfig --list | grep dhcp

  chkconfig --list | grep http

  chkconfig --level 345 httpd on

  chkconfig --level 345 dhcpd on

14) BMA

  cd /opt/infra

  /opt/infra/stopInfraAll.sh

  /opt/infra/startInfraAll.sh

Test PXE Setup

============

Create empty VM on PXE boot network

 

Grab MAC address from a sample VM (make sure vm is on the right network)

In UCSD go to

  Physical -> Compute -> PXE boot requests

  Set up the PXE boot request with above MAC address

  Select Setup PXE request

  The MAC address should show up a file in this directory

  cd /opt/cnsaroot/pxelinux.cfg

  ls -ltr

  [root@localhost pxelinux.cfg]# ls -ltr

  total 16

  -rw-r--r-- 1 root root 315 Feb 28  2011 01-d4-85-64-51-68-bc

  -rw-r--r-- 1 root root 315 Feb 28  2011 01-00-24-81-8a-46-0e.backup

  -rw-r--r-- 1 root root 596 Mar  1  2011 01-00-24-81-8a-46-0eoutput

  -rw-r--r-- 1 root root 914 Jun  7 18:43 01-00-50-56-a5-38-58

  [root@localhost pxelinux.cfg]#

  Boot the VM in vCenter

  Possible problems with

  /opt/cnsaroot/web/ks-repository/{this number changes}/ks.cfg

/optTop level ‘BMA’ directory folder
/opt/infraBMA infrastructure that has required start/stop scripts along with required Infrastructure, Properties for ‘CNSA’ runtime.

/opt/cnsarootTop level directory that has important ‘PXE’ related file(s) and subdirectories.

/opt/cnsaroot/pxelinux.cfg PXE configuration folder where configuration will be instantiated.

/opt/cnsaroot/templatesThis directory contains configuration file along with kick start file(s) that are required for bare metal to do PXE booting.

/opt/cnsaroot/imagesThis directory contains images of respective hypervisors that will be for installation over bare metal during PXE booting (e.g..esxi41_u1 directory contains PXE image for esx4i, etc.).

Trouble shooting (Thank you Davide PIZZA)

Discovered that the problem was not related to connection problems, in fact I had this as security warning and it was impossible to execute the script notify.ps1

Unknown.jpeg

tried all the possible modification of policies and even the Unblock-file cmdlets: nothing to do: the security warning appeared at each execution.

The solution was to move the notify.ps1 script into the C:\ volume (adding a command into the completed.bat file) and then it has been possible to bypass this security warning.

Hope this can help somebody.
