Adjust settings for automatically generated ONTAP ARP/AI snapshots
Summary
ONTAP 9.18.1 and
later do not include the following options:
- arw.high.encryption.alert.enabled
- arw.high.encryption.percentage.thresh
However, the
current documentation states that these options are available in ONTAP 9.17.1
and later.
Based on our
testing, these options are available only in ONTAP 9.17.1 and are not present
in ONTAP 9.18.1 or later.
The
documentation currently contains the following descriptions:
| arw.high.encryption.alert.enabled |
Enables alerts for high levels of encryption. When set to on (default), ONTAP sends an alert when the percentage of encryption exceeds the threshold specified in arw.high.encryption.percentage.threshold. |
ONTAP 9.17.1 and later |
| arw.high.encryption.percentage.threshold |
Specifies the maximum percentage of encryption for a volume. If the percentage of encryption exceeds this threshold, ONTAP handles the increase as an attack and creates an ARP/AI snapshot. arw.high.encryption.alert.enabled must be set to on for this option to take effect. |
ONTAP 9.17.1 and later |
The
following JIRA and Confluence pages also suggest that these options were
removed starting with ONTAP 9.18.1.
