Replication error only on some VMs - One or more source networks...

[briggs]

Hi. I am fairly sure I know the error, but I do not know why it's appearing now (didn't do before migrating to new ESXi8 hosts) and no idea at all why only 5 of 16 VM's.
The error is "One or more source networks were possibly mapped onto the same cloud network. Simultaneous partial failovers of VMs residing on those networks may result in issues
Processing finished with warnings"

I can't find the pattern. The VM's all have single NIC's, all on the same VLAN and network address range etc, mostly all Windows server OS's (the error exists for VMs Linux and Windows but only 5 of 16).

Where do I start in digging into more detail on this error please? As I say, the mapping networks process shouldn't be a thing as these VMs are no different to the others being backed up in terms of NIC config. I will run it past another pair of eyes internally in the mean time, but our Veeam replica's go to a third party DR providers datacentre, and their support team couldn't see why it's coming up now. As above, the same VM's on the old ESXi 6.7 were not triggering this error either.

Hello,

That sounds like a technical issue, if it has worked before. Please provide a support case ID for this issue, as requested when you click New Topic.
Without case number, the topic will eventually be deleted by moderators.

I assume the service provider and you have already checked out this KB:
https://www.veeam.com/kb2324

Maybe it make sense to have the service provider opening the case. We may need his Cloud Connect server logs as well to investigate the situation.

Best regards,
Fabian

PS: support can only help if you upload logs https://www.veeam.com/kb1832

Thanks Fabian, that alone is enough for me to pass this off to the service provider to resolve for now.

Do any of the VM's have multiple NIC's allocated on a different VLAN even disconnected?
