Azure Arc resource bridge maintenance operations

  • Статия

To keep your Azure Arc resource bridge deployment online and operational, you need to perform maintenance operations such as updating credentials, monitoring upgrades, and ensuring the appliance VM is online.

Prerequisites

To maintain the on-premises appliance VM, the appliance configuration files generated during deployment need to be saved in a secure location and made available on the management machine.

The management machine used to perform maintenance operations must meet all of the Arc resource bridge requirements.

The following sections describe the maintenance tasks for Arc resource bridge.

Update credentials in the appliance VM

Arc resource bridge consists of an on-premises appliance VM. The appliance VM stores credentials (for example, a user account for VMware vCenter) that are used to access the control center of the on-premises infrastructure to view and manage on-premises resources. The credentials used by Arc resource bridge are the same ones provided during deployment of the resource bridge. This allows the resource bridge visibility to on-premises resources for guest management in Azure.

If the credentials change, the credentials stored in the Arc resource bridge must be updated with the update-infracredentials command. This command must be run from the management machine, and it requires a kubeconfig file.

For more information, see Update the vSphere account credentials.

Troubleshoot Arc resource bridge

If you experience problems with the appliance VM, the appliance configuration files can help with troubleshooting. You can include these files when you open an Azure support request.

You might want to collect logs, which requires you to pass credentials to the on-premises control center:

  • For VMWare vSphere, use the username and password provided to Arc resource bridge at deployment.
  • For Azure Stack HCI, see Collect logs.

Delete Arc resource bridge

You might need to delete Arc resource bridge due to deployment failures, or when the resource bridge is no longer needed. To do so, you need the appliance configuration files.

The delete command is the recommended way to delete the Arc resource bridge. This command deletes the on-premises appliance VM, along with the Azure resource and underlying components across the two environments.
