Setting protection domain monitoring

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.

About this task

A chassis domain emphasizes the resiliency of the cluster to withstand a chassis-level failure. A node domain emphasizes a select group of nodes, potentially across 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.

Note: The selected cluster must be Element 11.0 or later to use protection domain monitoring; otherwise, protection domain functions are not available.

Steps

  1. Select NetApp Element Configuration > Clusters.
  2. Select the cluster on which you want to enable protection domain monitoring.
  3. Click Actions.
  4. In the resulting menu, click Set Protection Domain Monitoring.
  5. 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.
  6. Click OK.
