Hi,

 

as we are getting more Linux VM on our Nutanix AHV Environment, we just now deployed the Commvault FREL for AHV (Version 11.24).

The deplyoment and the registration wasn’t to difficult and we got it up and running.

But we still can’t browse a Linux VM, everytime we try to access the VM, we get the following error message:

 

“"Browse failed due to error while mounting virtual machine: Failed to retrieve VM information from Index Cache."”

We checked the connection between FREL, VSA and MediaAgent and they can communicate without any problems

The Brwose.log on the MediaAgent is showing this error:

On the FREL itself, i don’t have a FBR.log, only the cvd.log, but the network connection it is mentioning, are working, at least between the systems.

I already setup One-Way-Network Rules, to make sure, the connections are established and open.

But now im out of Ideas.

Can you please look under Device Manager/SCSI devices and tell me if you see ”Commvault Virtual Disk Controller”?  If so, does it show as enabled?

I raised a ticket with the support and we found some issues with the Commvault Virtual Disk Controller.

After starting the Browse and reveiving the error message in the GUI, we noticed that the CVVD is now disabled.

Support took some more logfiles and will look into it.

Thank you for the update.  Please update this thread with the progress of the case.

We finally got the problem solved.

The issue was with the commserver name, after we fixed it, the FREL is now working fine.
