L.3 Setting up the Active NOAM as Controller

1. Place the TPD OL7 DIU ISO and DSR DIU ISO on /var/TKLC/db/filemgmt of Active NOAM.
2. Create diuMajHosts file in /home/admusr of Active NOAM.

   Note:

   Description of diuMajHosts file:

   • image_name_tpd: TPD OL7 DIU ISO name should be given
   • image_name_dsr: DSR DIU ISO name should be given

   For DSR dual hop upgrade, use the groups as mentioned below:

   • Divide the servers into the groups with the XMI IP of the servers, which are required to be upgraded.
   • group1: We have included IP of Standby NOAM in group1, as this would be the first server that must be upgraded.
   • group2: In this group Active NOAM IP is included (Standby NOAM after switchover).
   • group3: This group contains the IP of Standby SOAM.
   • group4: This group contains the IP of Active SOAM.
   • group5 and group6: These groups contains the 50% of IP's of C level servers respectively.

   There can be n number of groups in the below file.

   Host name (host1, host2....) must be different for different groups.

   For example:

   [all:vars]
   image_name_tpd=TPD.install-8.0.0.0.0_90.12.0-OracleLinux7.4-x86_64-DIU.iso
   image_name_dsr=DSR-9.0.2.0.0_98.5.0-x86_64.iso
   
   [group1]
   host1 ansible_host=<XMI IP of StandBy NOAM> ansible_user=admusr ansible_port=22
   
   [group2]
   host2 ansible_host=<XMI IP of Active NOAM> ansible_user=admusr ansible_port=22
   
   [group3]
   host3 ansible_host=<XMI IP of Standby SOAM> ansible_user=admusr ansible_port=22
   
   [group4]
   host4 ansible_host=<XMI IP of Active SOAM> ansible_user=admusr ansible_port=22
   
   [group5]
   host5 ansible_host=10.75.237.93  ansible_user=admusr ansible_port=22  -----> DMP00
   host6 ansible_host=10.75.236.97  ansible_user=admusr ansible_port=22  -----> DIP00
   .
   .
   .
   [group6]
   host7 ansible_host=10.75.237.141ansible_user=admusr ansible_port=22  -----> DMP01
   host8 ansible_host=10.75.237.161ansible_user=admusr ansible_port=22  -----> DIP01
   .
   .
   .
