# HALB maintenance

When you need to replace or repair a HALB device (virtual machine), you can simply remove it from the Virtual Server configuration and then add the repaired or new device later. If you need to temporarily remove all HALB devices from a Virtual Server configuration, you can do that too.

You can also disable the Virtual Server during maintenance by clearing the **Enable HALB** option on the **General** tab in the Virtual Server properties dialog.
