SvSAN & VMware - Plugin VM Error When Registering With vCenter "Device "eth0" Does Not Exist."

This article is intended for administrators wishing to solve the error message when registering the Plugin VM with vCenter "Device "eth0" does not exist".

Note:  Although the error is shown the registration can seem successful but there is no plugin displayed in vCenter thought it can be visible in Administration>Client Plugins

Resolution/Information

Edit the netplan config file to update the device from the currently allocated name to eth0. As the register script is looking for a device that has this name.

Description of Problem

When running the register plugin command the following error: "Device "eth0" does not exist" is thrown and despite what looks a successful deployment there is no visible plugin in the vCenter or Datacenter object in Inventory View in vCenter.

sudo /opt/stormagic/SvSAN/bin/configure_plugin.sh -o register -v <vcenter fqdn> -u <username> -p -

Steps to Resolve:

Step 1 

Unregister the plugin from vCenter using the following syntax (adjust where necessary).

sudo /opt/stormagic/SvSAN/bin/configure_plugin.sh -o unregister -v <vCenter fqdn> -u <user name> -p -

Step 2

Now edit the .yaml file to change the name of the interface to eth0.First make a backup of the current config using the following syntax:

cp /etc/netplan/01-netplan-ansible.yaml /etc/netplan/01-netplan-ansible-bk.yaml

Step 3

Edit the exiting .yaml file and update the set command:

sudo nano /etc/netplan/01-netplan-ansible.yaml

Change the value in "set-name" to eth0. In this example it was ens192 - updated this to eth0 and saved changes.

Step 4

Apply changes with the following command

sudo netplan apply

Step 5

Register the plugin VM once more with vCenter using the same command as before:

sudo /opt/stormagic/SvSAN/bin/configure_plugin.sh -o register -v <vcenter fqdn> -u <username> -p -

Verify that the command has completed without warnings and that the plugin has been successfully registered in vCenter.
