Volumes window

You can use the Volumes window to manage your FlexVol volumes and Infinite Volumes and to display information about these volumes.

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

Command buttons

Create
Opens the Create Volume dialog box, which enables you to add a new volume.

This button is disabled if an Infinite Volume already exists.

Edit
Opens the Edit Volume dialog box, which enables you to modify a selected volume.
Delete
Deletes the selected volume or volumes.
Clone
Provides a list of clone options, including the following:
  • Create

    Creates a clone of the selected volume or a clone of a file from the selected volume.

  • Split

    Splits the clone from the parent volume.

  • View Hierarchy

    Displays information about the clone hierarchy.

The Clone option is not available for Infinite Volumes.

Status
Changes the status of the selected volume or volumes to one of the following statuses:
  • Online
  • Offline
  • Restrict

An Infinite Volume can go into a mixed state, which means its constituents are not all in the same state. However, you cannot set the status of an Infinite Volume to a mixed state, which is a read-only state. A mixed state typically occurs when most constituents are online but one constituent is offline. For example, if you take an aggregate offline that contains constituents, you also cause the constituents to go offline.

When you change the status of an Infinite Volume, the status of the constituents is changed one after the other. The Infinite Volume is in mixed state until the operation is complete.

Snapshot Copies
Provides a list of Snapshot options, including the following:
  • Create

    Displays the Create Snapshot dialog box, which you can use to create a new Snapshot copy of the selected volume.

  • Configure

    Configures the Snapshot settings.

  • Restore

    Restores a Snapshot copy of the selected volume.

Resize
Opens the Volume Resize wizard, which enables you to change the volume size.

This option is not available for Infinite Volumes with storage classes.

Storage Efficiency
Opens the Storage Efficiency dialog box, which you can use to manually start deduplication or to abort a running deduplication operation. This button is displayed only if deduplication is enabled on the storage system.

This option is not available for Infinite Volumes with storage classes.

Mount
Enables you to mount an Infinite Volume on the namespace of the Storage Virtual Machine (SVM) with Infinite Volume.
Unmount
Enables you to unmount an Infinite Volume before you change the junction path or delete the Infinite Volume.
Storage QoS
Opens the Quality of Service details dialog box, which you can use to assign one or more volumes to a new or existing policy group.

This option is not available for Infinite Volumes.

Move
Opens the Move Volume dialog box, which you can use to move volumes from one aggregate or node to another within the same SVM.
Protect by
Provides the list of data protection features that you can use to back up your data, including the following:
  • Mirror

    The mirror option is not available for Infinite Volumes that are associated with storage classes.

  • Vault

    The vault option is not available for Infinite Volumes.

Refresh
Updates the information in the window.

Volume list

The volume list displays the volume name and storage information about each volume.

Name
Displays the name of the volume.
Aggregate
Displays the name of the aggregate.
Status
Displays the status of the volume.
Thin Provisioned
Displays whether space guarantee is set for the selected volume. Valid values for online volumes are Yes and No.
Type
Displays the type of volume: rw for read/write, ls for load sharing, or dp for data protection.
Root volume
Displays whether the volume is a root volume.
% Used
Displays the amount of space (in percentage) that is used in the volume.
Available Space
Displays the available space in the volume.
Total Space
Displays the total space in the volume. This includes space that is reserved for Snapshot copies.
Storage Efficiency
Displays whether deduplication is enabled or disabled for the selected volume.
Policy Group
Displays the name of the Storage QoS policy group to which the volume is assigned. By default, this column is hidden.
Clone
Displays whether the volume is a FlexClone volume.

Details area

The area below the volume list contains four tabs that display detailed information about the selected volume.

Details tab
Displays general information about the selected volume, such as the maximum and current file count on the volume, cache policy of the volume hosted on a Flash Pool aggregate, policy group to which the volume is assigned, maximum throughput of the policy group, and export policy. The tab also displays whether an Infinite Volume is associated with storage classes.
Space tab
Displays the allocation of space in the volume.
  • Bar graph

    Displays, in graphical format, details about the volume space.

  • Volume

    Displays the total data space of the volume and the space reserved for Snapshot copies.

  • Available

    Displays the amount of space that is available in the volume for data and for Snapshot copies, and the total space available in the volume.

  • Used

    Displays the amount of space in the volume that is used for data and for Snapshot copies, and the total volume space that is used.

The Space Allocation tab displays different information, depending on whether the volume is configured for NAS or SAN. For a NAS volume, the tab displays the following information:

  • Used data space
  • Available data space
  • Used Snapshot reserve space
  • Available Snapshot reserve space (this is applicable only if the Snapshot reserve is greater than zero)

For a SAN volume, the tab displays the following information:

  • Space used by data in LUNs
  • Available space
  • Space used by Snapshot copies
Snapshot copies tab
Displays, in tabular format, 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 new Snapshot copy of the selected volume.

  • Rename

    Opens the Rename Snapshot Copy dialog box, which enables you to rename a selected Snapshot copy.

  • Delete

    Deletes the selected Snapshot copy.

  • Restore

    Restores the Snapshot copy.

  • Refresh

    Updates the information in the window.

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

    Displays, in graphical format, the volume space used by data and Snapshot copies. You can view details about the space used before and after applying 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 applied on the data on the volume are also displayed.

Data Protection tab
Displays data protection information related to the volume.

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

  • Destination Storage Virtual Machine

    Displays the SVM that contains the volume to which data is mirrored or vaulted in a relationship.

  • Destination Volume

    Displays the volume to which data is mirrored or vaulted in a relationship.

  • Is Healthy

    Displays the health of a relationship as Good or Bad.

  • Relationship State

    Displays the state of the relationship as Snapmirrored, Uninitialized, or Broken Off.

  • Transfer Status

    Displays the relationship status such as Idle, Transferring, or Aborting.

  • Type

    Displays the type of relationship as Vault or Mirror.

  • Lag Time

    Displays the difference between the current time and the timestamp of the Snapshot copy that was last transferred successfully to the destination storage system. It indicates the time difference between the data that is currently on the source system and the latest data stored on the destination system. The value that is displayed can be positive or negative. The value is negative if the time zone of the destination system is behind the time zone of the source storage system.

  • Policy

    Displays the SnapMirror policy that is assigned to the relationship.

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 SnapMirror relationships relating to a healthy cluster peer relationship. SnapMirror relationships relating to unhealthy cluster peer relationships are not displayed.
