You can manually enable protection domain monitoring using the NetApp Element Configuration extension point. You can select a protection domain threshold based on node or chassis domains.
Before you begin
- The selected cluster must be Element 11.0 or later to use protection domain monitoring; otherwise, protection domain functions are not available.
- Your cluster must have more than two nodes to use the protection domains feature. Compatibility with two-node clusters is not available.
About this task
A protection domain is a node or a set of nodes grouped together such that any node or all nodes in a domain might fail without causing the cluster to lose data availability. The protection domains feature allows you to monitor a cluster's resource capacity to ensure the cluster is still capable of healing from a failure event. You can select monitoring at either a node or chassis domain level:
- Node level defines each protection domain per individual node, with each node potentially located across chassis.
- Chassis level defines each protection domain by nodes that share a chassis.
A chassis domain requires more potential capacity resources than a node domain to be resilient to failure. When a protection domain threshold is exceeded, a cluster no longer has sufficient capacity to heal from failure while also maintaining undisrupted data availability.
Procedure
-
Select .
- Select the cluster on which you want to enable protection domain monitoring.
- Click Actions.
- In the resulting menu, click Set Protection Domain Monitoring.
- In the Set Protection Domain Monitoring dialog, select a failure threshold:
- Node: The threshold beyond which a cluster can no longer provide uninterrupted data during hardware failures at node level. The node threshold is the system default.
- Chassis: The threshold beyond which a cluster can no longer provide uninterrupted data during hardware failures at chassis level.
- Click OK.
Result
After you have set monitoring preferences, you can monitor protection domains from the
Reporting tab of the
NetApp Element Management extension point. See
Reporting overview.
