ESXi enables you to mark devices as local. This action is useful in cases when ESXi is unable to determine whether certain devices are local.
Make sure that the device is not shared.
Power off virtual machines that reside on the device and unmount an associated datastore.
- Browse to the host in the vSphere Web Client object navigator.
- Click the Configure tab.
- Under Storage, click Storage Devices.
- From the list of storage devices, select one or several remote devices to mark as local and click the All Actions icon.
- Click Mark as Local, and click Yes to save your changes.
