If VMware vSphere VMs store their disks on Cisco HyperFlex storages, they access the storage with the help of special Cisco HyperFlex HX Data Platform controllers. The controllers are dedicated VMs deployed on the same VMware ESX host that hosts the VMs.
By default, the controllers are configured to receive traffic only from the ESX host where they are located. To provide communication between Veeam Backup & Replication and Cisco HyperFlex storage, you need to manually enable the Direct NFS access mode between the backup proxy and the controllers.
To enable the Direct NFS access on a data platform controller:
- Log on to the controller with an account that has root privileges:
#ssh <user account>@<Controller IP Address>
- Enable the NFS traffic between the backup proxy and nfs share:
stcli security whitelist add --ips <Veeam NFS Data IP>
To verify backup proxy settings, use the following command:
stcli security whitelist list
Veeam Backup & Replication cannot back up VMs that have vSphere or HyperFlex snapshots created.
