Aggregates page

The Aggregates page displays information about the aggregates that are monitored and enables you to view and modify the threshold settings.

Command buttons

The command buttons enable you to perform the following tasks for a selected aggregate:

Edit Thresholds
Displays the Edit Aggregate Thresholds dialog box, which enables you to edit the threshold settings for one or more aggregates.
Export
Enables you to export the details of all the monitored aggregates to a comma-separated values (.csv) file.

Aggregates list

The Aggregates list displays, in tabular format, the properties of all the discovered aggregates. You can use the column filters to customize the data that is displayed:

Status
Displays the current status of the aggregate. The status can be Critical (Icon for event severity – critical), Error (Icon for event severity – error), Warning (Icon for event severity – warning), or Normal (Icon for event severity – normal).

You can move the pointer over the status to view more information about the event or events generated for the aggregate.

If the status of the aggregate is determined by a single event, you can view information such as the event name, time and date when the event was triggered, the name of the administrator to whom the event is assigned, and the cause of the event. You can click the View Details button to view more information about the event.

If the status of the aggregate is determined by multiple events of the same severity, the top three events are displayed with information such as the event name, time and date when the events are triggered, and the name of the administrator to whom the event is assigned. You can view more details about each of these events by clicking the event name. You can also click the View All Events link to view the list of generated events.

Aggregate
Displays the name of the aggregate.

You can move the pointer over an aggregate to view information such as the last generated event, node that contains the aggregate, RAID type, Snapshot reserve, Snapshot copies, and space allocated in the aggregate. You can also view the number of volume move operations that are currently in progress.

State
Displays the current state of the aggregate, which can be one of the following:
  • Offline

    Read or write access is not allowed.

  • Online

    Read and write access to volumes hosted on this aggregate is allowed.

  • Restricted

    Limited operations, such as parity reconstruction, are allowed, but data access is not allowed.

  • Creating

    The aggregate is being created.

  • Destroying

    The aggregate is being destroyed.

  • Failed

    The aggregate cannot be brought online.

  • Frozen

    The aggregate is (temporarily) not serving requests.

  • Inconsistent

    The aggregate has been marked corrupted; contact technical support.

  • Iron Restricted

    Diagnostic tools cannot be run on the aggregate.

  • Mounting

    The aggregate is being mounted.

  • Partial

    At least one disk was found for the aggregate, but two or more disks are missing.

  • Quiesced

    The aggregate is quiesced.

  • Quiescing

    The aggregate is being quiesced.

  • Reverted

    The revert operation of the aggregate is completed.

  • Unmounted

    The aggregate is offline.

  • Unmounting

    The aggregate is being taken offline.

  • Unknown

    Specifies that the aggregate is discovered, but the aggregate information is not yet retrieved by the Unified Manager server.

Type
Indicates whether the aggregate is a Flash Pool aggregate (combines HDDs and SSDs), or whether the disks in the aggregate are standard disks (HDDs only) or SSD disks (SSDs only).

For standard disks and SSD disks, this column is blank when the monitored storage system is running clustered Data ONTAP version earlier than 8.3.

Node
Displays the name of the storage controller that contains the aggregate.
Used Data Capacity
Displays the amount of space (in MB, GB, and so on) used for data in the aggregate. By default, this column is hidden.
Used Data %
Displays the percentage of space used for data in the aggregate. By default, this column is hidden.
Available Data Capacity
Displays the amount of space (in MB, GB, and so on) available for data in the aggregate.
Available Data %
Displays the percentage of space available for data in the aggregate. By default, this column is hidden.
Total Data Capacity
Displays the total data size (in MB, GB, and so on) of the aggregate.
Committed Capacity
Displays the total space (in MB, GB, and so on) committed for all the volumes in the aggregate.
RAID Type
Displays the RAID configuration type, which can be one of the following:
  • RAID0: All the RAID groups are of type RAID0.
  • RAID4: All the RAID groups are of type RAID4.
  • RAID-DP: All the RAID groups are of type RAID-DP.
  • Mixed RAID: The aggregate contains RAID groups of different RAID types (RAID0, RAID4, and RAID-DP).

Filters pane

The Filters pane enables you to set filters to customize the way information is displayed in the aggregates list. You can select filters related to the Status column.

Note: The filters specified in the Filters pane override the filters specified for the columns in the aggregates list.
