Unexpected Connection error with NetWorker and VBA

I was really looking forward to another idyllic day as a Backup Administrator.

Those days usually begin troubleshooting a few backup failures, drinking a lot of coffee and planning world domination. Sadly, I actually had to do some work today instead.

I found all my VMware protection policies had failed the previous evening.

error: Unable to connect to VBA, error Cannot establish session to VBA.
Logged onto vSphere and attempted to browse the backup recover area. Where we found the following error:

error: An unexpected connection error occurred and the cause could not be determined, Please check your EBR configuration screen to troubleshoot, or contact an administrator.

We rebooted the appliance and and it seemed to fix the issue for one. Ended up delving into the nuts and bolts of the various resources required to create a VBA backup. Let’s review these components.

EBR Config GUI

You can access the configuration interface by browsing to:

https://VBA:8543/ebr-configure/

Login via the root credentials of the appliance. The default password is 8RttoTriz

Note: I don’t know about you, but try as I might I could not access this via chrome.

VMUSER

In the GUI you can view running service and restart if required. You can also configure the connection to NetWorker. To do this you will need to know the password for the vmuser account. Near as I can tell the is an ID internal to NetWorker that is used to establish communication. The default password is “changeme”

CHANGING THE VMUSER PASSWORD

We hadn’t change this password. If you would like to change the password this can be done on the NetWorker server properties page under the misc tab. We also were not sure what the password was? Yeah, I know.

Re-establish communication between the appliance and NetWorker

Go to the NetWorker Config tab. Here you can enter the password and save to re-establish (and confirm the password) the interface with NetWorker. You will need to reboot the appliance after this.

This did resolve our issue and we can now browse the Backup Recovery interface in vSphere. With this re-established backups should run tonight. Fingers crossed.
