Viewing volume protection status

Contributors
PDFs

The Data Protection page presents a holistic view of the data protection details for all the protected volumes in a single cluster, or all clusters in a data center.

Steps

  1. In the left navigation pane, click Dashboard.

  2. Depending on whether you want to view data protection status for all monitored clusters or for a single cluster, select All Clusters or select a single cluster from the drop-down menu.

  3. Click the right-arrow at the top of the Data Protection panel. The Data Protection page is displayed.

Depending on whether you selected a single or all clusters in your data center, this page displays the data protection status of the volumes protected by Snapshot copies or SnapMirror policies, and also displays the count of the unprotected volumes.

Selecting a cluster from the Individual Cluster list displays the Snapshot protection and SnapMirror relationship status of the protected volumes in that cluster.

Clicking the events on this page takes you to the Event details page. You can click the View All link to view all active protection events in the Event Management inventory page. You can hover your mouse to view the respective counts and legends. You can click:

  • The bar charts for unprotected volumes and volumes protected by Snapshot copies to go to the Volumes page and view the details.

  • The bar charts for all relationships to go to the Relationships page, where the details are filtered by the source cluster.

View protection status of volumes protected by Snapshot copies

Snapshot Copies Overview: An overview of the volumes protected by Snapshot copies, such as:

  • The total number of volumes protected and not protected by Snapshot copies.

  • The total number of volumes that are using or exceeding the reserve space for the Snapshot copies.

Snapshot Copies Analysis details the following information:

  • Individual events for Snapshot copies, including the events raised in the last 24 hours.

  • Detailed chart for volumes protected and not protected by Snapshot copies.

  • Volumes using, not using, and breaching the reserved Snapshot copy capacity.

  • Break-up of the volume counts in terms of the number of their Snapshot copies.

Points to note for Snapshot copies

  • For counting the volumes protected by Snapshot copies, both source and destination volumes are considered.

  • The number of Snapshot copies returned is for only the volumes that are online and available.

  • The graph range for the number of Snapshot copies is dynamic. It is generated based on the number of snapshots present in the selected cluster.

  • For considering a volume as protected, the schedule for the Snapshot copy of the volume should be enabled.

  • The value for the reserve space for Snapshot copies is important for viewing the amount of disk space utilized or for calculating the space that can be reclaimed if one or more Snapshot copies are deleted.

View protection status for SnapMirror relationships

SnapMirror Overview: An overview of the volumes protected by SnapMirror policies, such as:

  • The number of volumes protected by the respective SnapMirror policies, such as, volume SnapMirror relationships, storage VM disaster recovery (SVM-DR), and their combinations.

  • The total number of SnapMirror relationships experiencing recovery point objective (RPO) lag based on the lag status.

SnapMirror Analysis details the following information:

  • Individual events raised for SnapMirror relationships, including the events raised in the last 24 hours

  • The number of volumes protected by each type of SnapMirror policy.

  • The number of relationships protected by the SnapMirror relationship types, such as Asynchronous Mirror, Asynchronous Vault, Asynchronous MirrorVault, StricxtSync, SnapMirror active sync consistency group, and Sync.

  • The number of healthy and unhealthy relationships.

  • Break-up of the volume relationship count. You can toggle the charts by RPO lag time and status.

  • Lag thresholds for unmanaged relationship. You can click the settings icon (Icon for lag threshold settings) to configure the lag threshold settings. For more information, see Configuring lag threshold settings for unmanaged protection relationships.

Points to note for SnapMirror relationships

  • For counting SnapMirror relationships, the source volumes, which are enabled for reading and writing, are counted. Destination and root volumes are not considered.

  • For SnapMirror relationship, the events are displayed for the source cluster.

  • The SnapMirror relationship count includes the number of volumes with sources and destinations on the same or different clusters.

  • The lag duration of the RPO lag in data replication is based on the SnapMirror relation. The status is categorized as ok, warning, or error, based on the relationship threshold set. You can look at the status to determine whether the parameters are working as expected, or whether you need to address any issue.

  • If a volume has multiple SnapMirror relationships, each relationship type is counted for the RPO lag.

  • Volume relationships are considered unhealthy if there are issues in data replication between the source and destination, for example, when the relationship is broken.

View clusters protected by MetroCluster configuration

The MetroCluster Protection panel on the Data Protection page displays the number of clusters protected or not protected by MetroCluster over FC or IP configuration at your site. Clicking the bar charts on this panel takes you to the Clusters page where the cluster details are filtered based on the protected or unprotected clusters. For information about monitoring your MetroCluster configuration, see Monitoring MetroCluster configurations.
