Health/Aggregates inventory page

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

Command buttons

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

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
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
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
The current state of the aggregate:
  • 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.

Node
The name of the storage controller that contains the aggregate.
Mirror Status
The mirror status of the aggregate:
  • Mirrored

    The aggregate plex data is mirrored.

  • Mirror degraded

    The aggregate plex data cannot be mirrored.

  • Mirror resynchronizing

    The aggregate plex data is being mirrored.

  • Failed

    The aggregate plex data mirroring failed.

  • Invalid configuration

    The initial state before an aggregate is created.

  • Uninitialized

    The aggregate is being created.

  • Unmirrored

    The aggregate is not mirrored.

  • CP count check in progress

    The aggregate has been assimilated and Unified Manager is validating that the CP counts for the plexes is similar.

  • Limbo

    There is an issue with the aggregate labels. The ONTAP system identifies the aggregate but cannot accurately assimilate the aggregate.

  • Needs CP count check

    The aggregate is assimilated but the CP counts on both plexes are not yet validated to be similar.

When an aggregate is in the mirror_resynchronizing state, then the resynchronization percentage is also shown.
In Transition
Whether the aggregate has completed transition or not.
Type
The aggregate type:
  • HDD
  • Hybrid

    Combines HDDs and SSDs, but Flash Pool has not been enabled.

  • Hybrid (Flash Pool)

    Combines HDDs and SSDs, and Flash Pool has been enabled.

  • SSD
  • SSD (FabricPool)

    Combines SSDs and an external capacity tier

  • VMDisk (SDS)

    Virtual disks within a virtual machine

  • VMDisk (FabricPool)

    Combines virtual disks and an external capacity tier

  • LUN (FlexArray)

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

SnapLock Type
The aggregate SnapLock Type. The possible values are Compliance, Enterprise, Non-SnapLock.
Used Data Capacity
The amount of space used for data in the aggregate.
Used Data %
The percentage of space used for data in the aggregate.
Available Data Capacity
The amount of space available for data in the aggregate.
Available Data %
The percentage of space available for data in the aggregate.
Total Data Capacity
The total data size of the aggregate.
Committed Capacity
The total space committed for all of the volumes in the aggregate.

For FabricPool aggregates, this value is relevant only to the local, or performance tier, capacity. The amount of space available in the external capacity tier is not reflected in this value.

Space Savings
The storage efficiency ratio based on the total logical space that is being used to store the data and the total physical space that would be required to store the data without using ONTAP storage efficiency technologies.

This field is applicable only to SSD aggregates, and only when the monitored storage system is running ONTAP version 9.0 or greater. This column is blank for other aggregate types and for older ONTAP versions.

RAID Type
The RAID configuration type:
  • RAID 0: All the RAID groups are of type RAID 0.
  • RAID 4: All the RAID groups are of type RAID 4.
  • RAID-DP: All the RAID groups are of type RAID-DP.
  • RAID-TEC: All the RAID groups are of type RAID-TEC.
  • Mixed RAID: The aggregate contains RAID groups of different RAID types (RAID 0, RAID 4, RAID-DP, and RAID-TEC).
External Capacity Tier Space Used
The amount of space being used in the external capacity tier; if the aggregate is a FabricPool aggregate.

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.
