In this article, we will discuss about FLR issue Specifically, how the FLR functionality breaks when a VDP IP/hostname reconfiguration is done. Thanks to one of our customer's who logged in a ticket with VMware for this issue. This would definitely be one of the most awaited workarounds.
So, in the vdp-configure page, under proxy you will have the proxy name as the hostname of the VDP appliance (If Internal proxy is being used) When a hostname change of VDP is done, this value does not get updated in addition to one of the proxy configuration files on which FLR is based. This causes FLR to give the error:
![]()
In the command line, you can run the below command to extract the name of the internal proxy:
In my case, I had a VDP with name vdp-dest.happycow.local with an IP. I changed this to vdp-new-dest.happycow.local. Then when I checked "hostname" and the proxy name using the above command, both of them reflected the updated address.
Due to this, your backups and full image restores continue to work without issues. FLR uses axionfs.cmd file to pull server parameters.
This file is located under:
If you vi this file, you will notice the --server parameter is still having the old FQDN.
--server=vdp-dest.happycow.local
--id=restoreonly

This causes FLR to give the error:
Failed to get disks: The VMDK filename is not valid or present. Verify that the proxy was correctly registered using the supported method in the documentation.

--primarybackupdir=by-number
--inactivity_timeout=172800
--encrypt=tls

So you will have to make sure the right FQDN is reflected under the --server parameter. Once this is done restart the axionfs service using:
# service axionfs restart
Post this, you should be able to perform FLR. The internal proxy would not reflect with the new hostname even if a re-register of proxy is done, however this should not be an issue.
Hope this helps.
