When configuring the environment for disaster recovery, the universal logical switch that is created in Region A is made available in region B and the virtual machines of vRealize Log Insight are moved to a different port group. You must update the SDDC Manager database in Region B to maintain connectivity for the virtual machines. You perform these steps in SDDC Manager in Region B only.

  2. Get the port group name for each Application Virtual Network.
    1. In the Networking inventory, expand the sfo01m01vc01.sfo01.rainpole.local tree and expand the sfo01-m01dc data center.
    2. Select the sfo01-m01-vds01 distributed switch, click the Networks tab, and click Distributed port groups.
    3. Locate the port group name for each Application Virtual Network and save the entries.
      Application Virtual Network Port Group Name
      Mgmt-xRegion01-VXLAN vxw-dvs-xxxx-Mgmt-xRegion01-VXLAN
      Mgmt-RegionB01-VXLAN vxw-dvs-xxxx-Mgmt-RegionB01-VXLAN
  3. Get the name of the UDLR.
    1. In the Networking and security inventory, click NSX Edges.
    2. From the NSX Manager drop-down menu, select 172.16.11.65.
    3. Locate the name of the sfo01m01udlr01 UDLR and write down the entry.
  4. Log in to SDDC Manager by using a Secure Shell (SSH) client.
    Setting Value
    FQDN lax01m01sddcmgr.lax01.rainpole.local
    User name vcf
    Password vcf_user_password
  5. Create a backup dump of the platform database as the root user by running the command.
    su -pg_dump --host=localhost -U postgres platform > platform.bak
  6. Login to platform database.
    psql -h localhost -U postgres -d platform
  7. Verify the current status of the AVN table by running the following command
    SELECT * FROM avn;
  8. Update the port group name for the Mgmt-xRegion01-VXLAN Application Virtual Network in SDDC Manager by using the entry you previously saved.
    update avn SET portgroup_name = 'vxw-dvs-xxxx-Mgmt-xRegion01-VXLAN' WHERE name = 'Mgmt-xRegion01-VXLAN';
  9. Update the port group and UDLR name for the Mgmt-RegionB01-VXLAN Application Virtual Network in SDDC Manager by using the entries you previously saved.
    update avn SET name = 'Mgmt-RegionB01-VXLAN' WHERE name = 'Mgmt-RegionA01-VXLAN';
    update avn SET portgroup_name = 'vxw-dvs-xxxx-Mgmt-RegionB01-VXLAN' WHERE name = 'Mgmt-RegionB01-VXLAN';
    update avn set region_type = 'REGION_B' WHERE name = 'Mgmt-RegionB01-VXLAN';
    update avn set router_name = 'm01udlr01' WHERE name = 'Mgmt-RegionB01-VXLAN';
  10. Verify that the values are updated and exit the platform database.
    SELECT * FROM avn;
