You can add a trunk or access interface to a VM node after the node has been installed. The interfaces you add are displayed on the VLAN interfaces page and the HA groups page.

Before you begin

  • You have access to the instructions for installing StorageGRID on your VMware platform.

  • You have Admin Node and Gateway Node VMware virtual machines.

  • You have a network subnet that is not being used as Grid, Admin, or Client Network.

  • You have the Passwords.txt file.

  • You have specific access permissions.

Important Don't attempt to add interfaces to a node while a software upgrade, recovery procedure, or expansion procedure is active.
About this task

Use these steps to add one or more extra interfaces to a VMware node after the node has been installed. For example, you might want to add a trunk interface to an Admin or Gateway Node, so you can use VLAN interfaces to segregate the traffic belonging to different applications or tenants. Or you might want to add an access interface to use in a high availability (HA) group.

If you add a trunk interface, you must configure a VLAN interface in StorageGRID. If you add an access interface, you can add the interface directly to an HA group; you don't need to configure a VLAN interface.

The node might be unavailable for a brief time when you add interfaces.

Steps

  1. In vCenter, add a new network adapter (type VMXNET3) to an Admin Node and Gateway Node VM. Select Connected and Connect At Power On checkboxes.

    vCenter

  2. Use SSH to log in to the Admin Node or Gateway Node.

  3. Use ip link show to confirm the new network interface ens256 is detected.
