Volumes window

You can use the Volumes window to manage your FlexVol volumes and FlexGroup volumes, and to display information about them.

You cannot view or manage volumes that are in storage virtual machines (SVMs) that are configured for disaster recovery (DR) by using System Manager. You must use the command-line interface (CLI) instead.

Note: The command buttons and list of columns will differ based on the type of volume that is selected. You can view only those command buttons and columns that are applicable for the selected volume.

Displays the total space in the volume, which includes the space that is reserved for Snapshot copies.
% Used
Displays the amount of space (in percentage) that is used in the volume.
Logical Used %
Displays the amount of logical space (in percentage), including space reserves, that is used in the volume irrespective of whether logical space reporting is enabled or not.
Note: This field is displayed only if you have enabled logical space reporting by using the CLI.
Logical Space Reporting
Displays whether logical space reporting is enabled on the volume.
Note: This field is displayed only if you have enabled logical space reporting by using the CLI.
Logical Space Enforcement
Displays whether to perform logical space accounting on the volume.
Type
Displays the type of volume: rw for read/write, ls for load sharing, or dp for data protection.
Protection Relationship
Display whether the volume has a protection relationship initiated.

If the relationship is between an ONTAP system and a non-ONTAP system, the value is displayed as No by default.

Storage Efficiency
Displays whether deduplication is enabled or disabled for the selected volume.
Encrypted
Displays whether the volume is encrypted or not.
QoS Policy Group
Displays the name of the Storage QoS policy group to which the volume is assigned. By default, this column is hidden.
SnapLock Type
Displays the SnapLock type of the volume.
Clone
Displays whether the volume is a FlexClone volume.
Is Volume Moving
Displays whether a volume is being moved from one aggregate to another aggregate, or from one node to another node.
Tiering Policy
Displays the tiering policy of a FabricPool-enabled aggregate. The default tiering policy is " snapshot-only".
Application
Displays the name of the application that is assigned to the volume.

Details area

You can select a volume to view information about the selected volume. You can click Show More Details to view detailed information about the selected volume.

Overview tab
Displays general information about the selected volume, and displays a pictorial representation of the space allocation of the volume, the protection status of the volume, and the performance of the volume. The Overview tab displays information about the encryption status of the volume, such as the conversion status or rekey status, information about a volume that is being moved, such as the state and phase of the volume move, the destination node and aggregate to which the volume is being moved, the percentage of volume move that is complete, the estimated time to complete the volume move operation, and details of the volume move operation. This tab also displays information about whether the volume is blocked for input/output (I/O) operations and the application blocking the operation.

For FlexCache volumes, details about the origin of the FlexCache volume are displayed.

The refresh interval for performance data is 15 seconds.

This tab contains the following command button:

Cutover
Opens the Cutover dialog box, which enables you to manually trigger the cutover.

The Cutover command button is displayed only if the volume move operation is in the "replication" or "hard deferred" state.

Snapshot Copies tab
Displays the Snapshot copies of the selected volume. This tab contains the following command buttons:
Create
Opens the Create Snapshot Copy dialog box, which enables you to create a Snapshot copy of the selected volume.
Configuration Settings
Configures the Snapshot settings.
Delete
Deletes the selected Snapshot copy.
More Actions > Rename

Data Protection tab
Displays data protection information about the selected volume.

If the source volume (read/write volume) is selected, the tab displays all of the mirror relationships, vault relationships, and mirror and vault relationships that are related to the destination volume (DP volume). If the destination volume is selected, the tab displays the relationship with the source volume.

If some or all of the cluster peer relationships of the local cluster are in an unhealthy state, the Data Protection tab might take some time to display the protection relationships relating to a healthy cluster peer relationship. Relationships relating to unhealthy cluster peer relationships are not displayed.

Storage Efficiency tab
Displays information in the following panes:
  • Bar graph

    Displays (in graphical format) the volume space that is used by data and Snapshot copies. You can view details about the space used before and after applying settings for storage efficiency savings.

  • Details

    Displays information about deduplication properties, including whether deduplication is enabled on the volume, the deduplication mode, the deduplication status, type, and whether inline or background compression is enabled on the volume.

  • Last run details

    Provides details about the last-run deduplication operation on the volume. Space savings resulting from compression and deduplication operations that are applied on the data on the volume are also displayed.

Performance tab
Displays information about the average performance metrics, read performance metrics, and write performance metrics of the selected volume, including throughput, IOPS, and latency.

Changing the client time zone or the cluster time zone impacts the performance metrics graphs. You must refresh your browser to view the updated graphs.
