API call 'perf-object-get-instances-iter-start' fails for a DR backup vfiler

Is it possible to get performance data for filers in DR mode?
We are trying to collect performance data from a filer which is running in DR mode (version 8.1.4). But 'perf-object-get-instances-iter-start' call fails with the following message: "Error 13070: vfiler is acting as a DR backup". Does it mean that this call is not supported for DR backups?


Any help would be very appreciated.
