The ONTAP ARP feature for SAN volumes is not supported in ONTAP 9.16.1 and earlier. It's recommended that you disable ARP on SAN volumes before reverting to ONTAP 9.16.1 or earlier to prevent the feature from staying active and using CPU and disk resources without performing any actual detection on the reverted version.

Example 1. Steps
System Manager

  1. Select Storage > Volumes, then select the name of the volume.

  2. In the Security tab of the Volumes overview, select Status to switch from Enabled to Disabled.

CLI

  1. Disable ransomware protection on a volume:

    security anti-ransomware volume disable -volume <vol_name> -vserver <svm_name>
