Specifying interface for Snapvault?

PARISALLSTON — Thu, 05 Jun 2025 06:37:48 GMT

Hi All,

Does anyone know how to configure OnCommand so that filers use a particular interface for SnapVault? IHAC that is using a vif for replication, and want to use that IP.

Can't find aything in the docs on this

Thanks.

AFAIK one can configure the controller option:

options ndmpd.preferred_interface 'vif_name'

Then it should be used by the transfers OC is kicking off. Maybe need to upgrade to OC 5.0D1 first...

Hope this helps,

Peter

You can either upgrade to 5.0D1 or turn on the following options and live with the version you are

dfm options set ndmpDataUseAllInterfaces=yes.

One note on this setting. If you have a VIF with multiple sub-interfaces\VLANS you must set the preferred interface to one of those VLANs. For example if you have:

toplvl_vif and then

toplvl_vif-2 (VLAN2)

toplvl_vif-3 (VLAN3)

toplvl_vif-4 (VLAN4)

Let's say you want SnapVault to transfer over the VLAN4 network - you should set options ndmpd.preferred_interface to:

options ndmpd.preferred_interface toplvl_vif-4
