4.1.9 Shutting Down 20% of DP Server

Perform the following procedure to shutdown 20% of DP Server.
  1. Remove DP from topology.
    1. Login to Active NOAM SDS GUI.
    2. Navigate to Status & Manage from Main Menu, then select HA.
    3. To change HA state of DP to Out of Service (OOS), perform the following steps:
      1. To change DP HA state to OOS, perform the following steps:
        1. Navigate to Status & Manage from Main Menu, then select HA.
        2. Click Edit and change Max Allowed HA Role of DP to OOS.
      2. To remove the DP from DP Server group, perform the following steps:
        1. Navigate to Configuration from Main Menu, then select Server Groups.
        2. Select DP (Level C) Server Group and click Edit.
        3. Uncheck DP from Server Group and click OK.
      3. Navigate to Configuration from Main Menu, then select Servers and select DP. Click Delete.
  2. Shutdown DP by running the following command:
    sudo shutdown -h now
  3. Install OL8 and KVM on the shutdown BM server.
  4. Create vSDS 9.0.X.

    Note:

    Create DP on the same host where NOAM, SOAM VM was created.
  5. Assign XMI IP to new vSDS 9.0.X.
    To configure netmask and XMI IP address values, run the following command:
    sudo /usr/TKLC/plat/bin/netAdm set --onboot=yes --netmask=<netmask> --device=eth0 --address=<IP address>
  6. Login to SDS Active vSDS 9.0.1 NOAM using XMI.
  7. Navigate to Configuration from Main Menu, then select Servers.
  8. Click Insert.
  9. Add the following details for DP server:
    • Enter DP hostname
    • Update Role as MP
    • Hardware Profile as SDS Cloud Guest
    • Configure XMI and IMI, XSI IP's and NTP server IP
  10. Click Ok.
  11. Select the required DP server (which was created in the previous step).
  12. Click Export, to export server configuration file to the file management folder on the Active NOAM.
  13. Now ssh to Active SDS 9.0.X NOAM and copy the TKLCConfigData.<hostname>.sh file to the newly created vSDS 9.0.X DP. After copying the file wait for 5 minutes.
    cd $FILE_MGMT_AREA
    sudo scp TKLCConfigData.<hostname>.sh admusr@<XMI IP of newly created vSDS 9.0.X DP>:/var/tmp/TKLCConfigData.sh
  14. SSH to newly created vSDS 9.0.X DP XMI IP and verify the /var/TKLC/appw/logs/Process/install.log log file for successfully running of TKLCConfigData.sh file. You can run following command to check logs.
    sudo tail -f /var/TKLC/appw/logs/Process/install.log
    Output:

  15. Wait for 10 minutes for server to configure with the IP configuration, then reboot the VM using sudo init 6 command on CLI.
  16. Login to Active vSDS NOAM GUI.
  17. Navigate to Configuration from Main Menu, then select Server Groups.
  18. Select the DP (Level C) Server group and click Edit.
  19. Select the newly added vSDS 9.0.X DP to add to the DP Server group, then click Ok to save the changes and wait for 5 minutes.
  20. If the Max Allowed HA Role of new 9.0.X vSDS DP is not Active then navigate to Status & Manage from Main Menu, then select HA and change Max Allowed HA Role of that server to Active by clicking Edit.
  21. SSH to new vSDS 9.0.X DP.
  22. Run the following commands to disable the upgrade barrier feature:
    iset -fvalue=1 IdbParamDef where "param='IdbDisableUpgBarrier'"
sudo init 6
  23. Login to Active vSDS NOAM GUI.
  24. Navigate to Status & Manage from Main Menu, then select Server and select the newly added vSDS 9.0.X DP. Click Restart.

    Note:

    • To configure remaining DPs, repeat procedure Shutting Down 20% of DP Server for each 20% of DP until you reach 100% of DP server.
    • DP leader must be migrated last.
