Question

Live browse of guest files from a cloud library from a MA in the cloud

We have the following scenario:

Cloud library → shared between MA1(windows vm on prem) ; MA2(azure VM windows) 

VMware VM (backed up using VSA) backed up by MA1

Browse and restore from MA1 works

services stopped on MA1

Browse and restore from MA2 fails → “Browse failed due to error while mounting virtual machine.”

We see that the cvvd driver is not loaded on MA2 wheras it is on MA1. (As per https://documentation.commvault.com/11.24/expert/30807_live_browse_and_block_level_browse.html Block-level browse uses a block-level driver to mount a pseudo disk on the MediaAgent being used for browse and restore operations.; Cloud Library Support for Live Browse

For all VSA hypervisors that support live browse, you can perform live browse operations with the following cloud libraries: Microsoft Azure Storage: Default container storage using hot or cold access tiers with General Purpose v1 (GPv1) or General Purpose v2 (GPv2) storage account

 

Question is : Is live browse supported for MAs in Azure?

Hello @neuwiesener 

Does MA2 have the Virtual Server Agent installed on it? You can see if you go to the properties of the client and go to the “Version” tab.

@Dan White Yes it is.

@neuwiesener Are you able to specify the MA2 during the browse from the “advanced options” tab before submitting the browse?

What kind of storage is this located on? Archive cloud storage?

Hey @neuwiesener , following up to see if specifying the MA during the browse did the trick.

Thanks!

Hey @neuwiesener , following up one more time to see if you have anything you can add (or if the issue persists).

Thanks!

Another point here - Only one media agent can hold the index cache at once. There needs to be connectivity between Media Agents to allow the non-hosting MA to lookup the index cache info. So if MA1 holds the index, and the browse request happens through MA2, then MA2 will reach MA1 to read the index.

Using Media Agent here interchangeably for VSA as well (assume the MA has VSA installed :grinning:

@Damian Andre MA 1 and MA2 both have VSA installed. Shouldn't the index get restored from the backup if the MA holding index goes down due to DR? Issue persists.

@neuwiesener I have asked around about this and suggestions are to open a case.  Can you share the case number with me when you do?
