Veeam B&R suddenly failing backup: Processing SERVER Error: VM 'SERVER' (ref: 'vm-68') is 'Disconnected'

Hi All,

Suddenly having an issue backup up VMs on VMWARE using Veeam B&R (up to date).

The backup fails with the error: Processing SERVER Error: VM 'SERVER' (ref: 'vm-68') is 'Disconnected'

The VM is not disconnected but in the logs I see:

When the back tries to run.

The storage is iSCSi presented on 10GB Ethernet dedicated links.

NAS is alive and well and operating normally and is a Synology RS3617xs+ running latest DSM Image.

The host, the VM and the NAS have all been rebooted.

What is happening to cause this error?

Thanks

Andy

Is the device "eui.00e04c2020202000" / "vmhba32:C0:T0:L0" the iSCSI LUN where the VM is located? If so, how many paths do you see for this LUN?

Which vCenter and ESXi Version are you running?

Are other hosts / VMs in your cluster also effected?
