How to update VXLAN portgroup info in VMware Cloud Foundation DR implementation

Products

• VMware Cloud Foundation

Issue/Introduction

This article provides instructions for updating VXLAN portgroup info in a disaster recovery configuration within VMware Cloud Foundation.

Environment

VMware Cloud Foundation 3.0.x

Resolution

About the update_vrealize_portgroup.py utility

In the VVD guidance documentation, one of the steps is to move the vRealize VMs from the original VREALIZE VLAN to a VXLAN created on the NSX vRealize-Edge. As part of this, there is a need to update the Cassandra database with the VXLAN portgroup created for the vRealize-Edge.

Installation

Prerequisites:

• Network connectivity between management VLANs in RegionA and RegionB.
• IP address of the SDDC Manager VM in RegionA.
• root password of the SDDC Manager VM in RegionA.
• vRealize Automation and vRealize Operations components should be deployed in RegionA only.

For VMware Cloud Foundation 3.0.x / 3.5.x

1. Download the attached 59203_update_vrealize_portgroup.zip file.
2. Use a file transfer utility to copy the 59203_update_vrealize_portgroup.zip file to the /tmp directory on the RegionA SDDC Manager Controller VM.
3. SSH to the SDDC Manager Controller VM in RegionA as the vcf user. Issue the su - commands to switch to the root user.
4. Issue the following commands to extract the script:

unzip -d /tmp/ /tmp/59203_update_vrealize_portgroup.zip

Update vRealize portgroup

In the VVD guidance documentation, one of the steps is to move the vRealize VMs from the original VREALIZE VLAN to a VXLAN created on the NSX vRealize-Edge. The VXLAN portgroup created for the vRealize-Edge must be updated in the Cassandra database. Issue a command similar to the following on the SDDC Manager VM in RegionA to update the portgroup in Cassandra:

python /tmp/update_vrealize_portgroup.py --portgroup vxw-dvs-9-universalwire-2-sid-12002-Mgmt-xRegion01-VXLAN

Note: Replace the portgroup name in the previous command, vxw-dvs-9-universalwire-2-sid-12002-Mgmt-xRegion01-VXLAN, with the name that was created in the vSphere Web Client.
 

For VMware Cloud Foundation 3.7.x

In 3.7.x, the tables in the Cassandra database have been moved to the Postgres database. With this change the process has been simplified to a single SQL statement. 

1.  Open an SSH session to the SDDC Manager VM in RegionA and change to the root user

su -

1. Run the below query:

psql --host=localhost -U postgres -c '\c platform;' -c "update network set port_group_key_name = '<your-new-port-group-name>';" -c 'select * from network' -x
