The Health/Volumes inventory page displays information about the volumes in the storage systems that are monitored and enables you to modify the volume threshold settings.
Enables you to create a SnapMirror relationship for the selected volumes.
Enables you to create a SnapVault relationship for the selected volumes.
The volumes table displays the properties of all the discovered volumes. You can use the column filters to customize the data that is displayed:
You can move the pointer over the status to view more information about the event or events generated for the volume.
If the status of the volume 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 link to view more information about the event.
If the status of the volume 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.
You can move the pointer over a volume to view information such as the qtree quota overcommitted space, status of the last volume move operation, and space allocated in the volume. You can also view the details of related objects such as the SVM to which the volume belongs, the aggregate to which the volume belongs, and all the volumes that belong to this aggregate.
If an SVM with Infinite Volume is monitored, you can view details about the three types of constituents (data, namespace, and namespace mirror) in the SVM with Infinite Volume. The constituent details include the following information:
Read or write access to the volume is not allowed.
Read and write access to the volume is allowed.
Limited operations, such as parity reconstruction, are allowed, but data access is not allowed.
The constituents of a FlexGroup volume are not all in the same state.
You can click the name to display details in the Aggregate details page. For FlexGroup volumes, you can click the number to display the aggregates that are used in the FlexGroup in the Aggregates page.
A read/write volume with no outgoing or incoming SnapMirror or SnapVault relationships
A read/write volume with an outgoing SnapMirror or SnapVault relationship
A data protection (DP) volume or read/write volume with an incoming SnapMirror or SnapVault relationship
A volume for which protection roles do not apply, such as a load sharing volume, data constituent, or temporary volume
You can move your pointer over the protection role for a volume to display a graphical representation of the protection topology for the selected volume, including, if applicable, the source volume, the total number of outgoing SnapMirror relationships, and the total number of outgoing SnapVault relationships. Blue highlighting around the volume indicates the selected volume.
Clicking View Protection Details displays the Protection tab of the Health/Volume details page.
Logical space indicates the real size of the data that is being stored on the volume without applying the savings from using ONTAP storage efficiency technologies.
You can move the pointer over the status to view more information about the volume move operation, such as the source, destination, operation start time, operation end time, current phase of the volume move operation that is in progress, status (in percentage), and estimated end time.
Cache policy | Description |
---|---|
Auto | Read caches all the metadata blocks and randomly read user data blocks, and write caches all the randomly overwritten user data blocks. |
None | Does not cache any user data or metadata blocks. |
All | Read caches all the user data blocks that are read and written. The policy does not perform any write caching. |
All-Random Write | This policy is a combination of the All and
No Read-Random Write policies and performs the following actions:
|
All Read | Read caches all the metadata, randomly read, and sequentially read user data blocks. |
All Read-Random Write | This policy is a combination of the All Read and No Read-Random Write policies and performs the following actions:
|
All Read Random Write | Read caches all the metadata, randomly read, sequentially read, and randomly written user data blocks. |
All Read Random Write-Random Write | This policy is a combination of the All Read Random Write and No Read-Random Write policies and does the following:
|
Meta | Read caches only metadata blocks. |
Meta-Random Write | This policy is a combination of the Meta and
No Read-Random Write and does the following:
Read caches only |
No Read-Random Write | Write caches all the randomly overwritten user data blocks. The policy does not perform any read caching. |
Random Read | Read caches all the metadata blocks and randomly read user data blocks. |
Random Read-Write | Read caches all the metadata, randomly read, and randomly written user data blocks. |
Random Read-Write-Random Write | This policy is a combination of the Random Read Write and No Read-Random Write policies and does the following:
|
Cache the cold volume blocks for the lowest time
Cache the cold volume blocks for the default time
Cache the cold volume blocks for the highest time
You can click the node name to display details in the Node details page. For FlexGroup volumes, you can click the number to display the nodes that are used in the FlexGroup in the Nodes page.
The Filters pane enables you to set filters to customize the way information is displayed in the volumes list. You can select filters related to the Volume Status, State, and Annotation columns.
