## Examples

::: example
### Unmounting Object Storage Repository

This example shows how to unmount the `Amazon OS` object storage repository. The cmdlet will skip all notifications and warnings.

```
$repository = Get-VBRObjectStorageRepository -Name "Amazon OS"
Unmount-VBRObjectStorageRepository -Repository $repository -Force
```

Perform the following steps:

1. Run the [`Get-VBRObjectStorageRepository`](get-vbrobjectstoragerepository.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$repository` variable.
2. Run the `Unmount-VBRObjectStorageRepository` cmdlet. Set the `$repository` variable as the `Repository` parameter value. Provide the `Force` parameter.
