Error: command failed: Internal error. Failed to restore firewall policies
to prepare for revert of management and data network interface services.
Reason: Internal error. Failed to remove firewall service "none" because
this service is being used by firewall policy "data" on Vserver "Vserver name".
Use the "system services firewall policy show -service none" command
to review firewall policies referencing this service. If necessary,
use the "system services firewall policy delete" command to remove
references to this service. Wait a few minutes, then try the command again.
