B.3 Setting up the Active NOAM as Controller

1. Place the TPD OL7 DIU ISO and SDS 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: SDS DIU ISO name should be given

   For the SDS Dual hop upgrade, use the groups as mentioned below:

   • Divide the servers into the groups with the xmi IP of the servers that need to be upgraded, as shown in the example below.
   • group1 → We have included the IP of Stanby Noam in group1, as this would be the first server we want to upgrade.
   • group2 → In this group Active Noam IP is included. (Stanby noam after switchover) and Query Server
   • group3 → This group will contain the IP of Standby Soam.
   • group4 → This group will contain the IP of Active Soam.
   • group5 and group6→ These groups will contain 50% 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 OL7 DIU ISO
   image_name_sds=SDS DIU 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
   host3 ansible_host=<XMI IP of Query Server>  ansible_user=admusr ansible_port=22
   
   [group3]
   host4 ansible_host=<XMI IP of Standby SOAM> ansible_user=admusr ansible_port=22
   
   [group4]
   host5 ansible_host=<XMI IP of Active SOAM> ansible_user=admusr ansible_port=22
   
   [group5]
   host6 ansible_host=10.75.237.93  ansible_user=admusr ansible_port=22  -----> DMP00
   .
   .
   .
   [group6]
   host8 ansible_host=10.75.237.141ansible_user=admusr ansible_port=22  -----> DMP01
   .
   .
   .
