NOTICE

Description

This message occurs after the anti-ransomware feature has completed its workload evaluation on the volume and determined that the data entropy is high. Consequently, the anti-ransomware feature cannot effectively differentiate between expected workload characteristics and ransomware characteristics. Maintaining the anti-ransomware feature on this volume offers no benefit.

Corrective Action

If the specified volume contains only LUNs or NVMe namespaces, then it is recommended to disable the anti-ransomware feature. For more information, search on "ONTAP Autonomous Ransomware Protection"

Syslog Message

Volume "%s" in SVM "%s" is unsuitable for anti-ransomware block device analysis.

Parameters

volumeName (STRING): Name of the volume.
vserverName (STRING): Name of the SVM.
