You can use the Health/Volume details page to view detailed information about a selected volume, such as capacity, storage efficiency, configuration, protection, annotation, and events generated. You can also view information about the related objects and related alerts for that volume.

You must have the OnCommand Administrator or Storage Administrator role.

Command buttons

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

  • Switch to Performance View

    Enables you to navigate to the Performance/Volume details page.

  • favorite icon

    Enables you to add the selected volume to the Favorites dashboard.

  • Actions

    • Add Alert

      Enables you to add an alert to the selected volume.

    • Edit Thresholds

      Enables you to modify the threshold settings for the selected volume.

    • Annotate

      Enables you to annotate the selected volume.

    • Protect

      Enables you to create either SnapMirror or SnapVault relationships for the selected volume.

    • Relationship

      Enables you to execute the following protection relationship operations:

      • Edit

        Launches the Edit Relationship dialog box which enables you to change existing SnapMirror policies, schedules, and maximum transfer rates for an existing protection relationship.

      • Abort

        Aborts transfers that are in progress for a selected relationship. Optionally, it enables you to remove the restart checkpoint for transfers other than the baseline transfer. You cannot remove the checkpoint for a baseline transfer.

      • Quiesce

        Temporarily disables scheduled updates for a selected relationship. Transfers that are already in progress must complete before the relationship is quiesced.

      • Break

        Breaks the relationship between the source and destination volumes and changes the destination to a read-write volume.

      • Remove

        Permanently deletes the relationship between the selected source and destination. The volumes are not destroyed and the Snapshot copies on the volumes are not removed. This operation cannot be undone.

      • Resume

        Enables scheduled transfers for a quiesced relationship. At the next scheduled transfer interval, a restart checkpoint is used, if one exists.

      • Resynchronize

        Enables you to resynchronize a previously broken relationship.

      • Initialize/Update

        Enables you to perform a first-time baseline transfer on a new protection relationship, or to perform a manual update if the relationship is already initialized.

      • Reverse Resync

        Enables you to reestablish a previously broken protection relationship, reversing the function of the source and destination by making the source a copy of the original destination. The contents on the source are overwritten by the contents on the destination, and any data that is newer than the data on the common Snapshot copy is deleted.

    • Restore

      Enables you to restore data from one volume to another volume.

    Note

    The Restore button and the Relationship operation buttons are not available for FlexGroup volumes, or for volumes that are in synchronous protection relationships.

  • View Volumes

    Enables you to navigate to the Health/Volumes inventory page.

Capacity tab

The Capacity tab displays details about the selected volume, such as its physical capacity, logical capacity, threshold settings, quota capacity, and information about any volume move operation:

  • Capacity Physical

    Details the physical capacity of the volume:

    • Snapshot Overflow

      Displays the data space that is consumed by the Snapshot copies.

    • Used

      Displays the space used by data in the volume.

    • Warning

      Indicates that the space in the volume is nearly full. If this threshold is breached, the Space Nearly Full event is generated.

    • Error

      Indicates that the space in the volume is full. If this threshold is breached, the Space Full event is generated.

    • Unusable

      Indicates that the Thin-Provisioned Volume Space At Risk event is generated and that the space in the thinly provisioned volume is at risk because of aggregate capacity issues. The unusable capacity is displayed only for thinly provisioned volumes.

    • Data graph

      Displays the total data capacity and the used data capacity of the volume.

      If autogrow is enabled, the data graph also displays the space available in the aggregate. The data graph displays the effective storage space that can be used by data in the volume, which can be one of the following:

      • Actual data capacity of the volume for the following conditions:

        • Autogrow is disabled.

        • Autogrow-enabled volume has reached the maximum size.

        • Autogrow-enabled thickly provisioned volume cannot grow further.

      • Data capacity of the volume after considering the maximum volume size (for thinly provisioned volumes and for thickly provisioned volumes when the aggregate has space for the volume to reach maximum size)

      • Data capacity of the volume after considering the next possible autogrow size (for thickly provisioned volumes that have an autogrow percentage threshold)

    • Snapshot copies graph

      This graph is displayed only when the used Snapshot capacity or the Snapshot reserve is not zero.

    Both the graphs display the capacity by which the Snapshot capacity exceeds the Snapshot reserve if the used Snapshot capacity exceeds the Snapshot reserve.

  • Capacity Logical

    Displays the logical space characteristics of the volume. The logical space indicates the real size of the data that is being stored on disk without applying the savings from using ONTAP storage efficiency technologies.

    • Logical Space Reporting

      Displays if the volume has logical space reporting configured. The value can be Enabled, Disabled, or Not applicable. “Not applicable” is displayed for volumes on older versions of ONTAP or on volumes that do not support logical space reporting.

    • Used

      Displays the amount of logical space that is being used by data in the volume, and the percentage of logical space used based on the total data capacity.

    • Available

      Displays the amount of logical space that is still available for data in the volume, and the percentage of logical space available based on the total data capacity.

    • Logical Space Enforcement

      Displays whether logical space enforcement is configured for thinly provisioned volumes. When set to Enabled, the logical used size of the volume cannot be greater than the currently set physical volume size.

  • Autogrow

    Displays whether the volume automatically grows when it is out of space.

  • Space Guarantee

    Displays the FlexVol volume setting control when a volume removes free blocks from an aggregate. These blocks are then guaranteed to be available for writes to files in the volume. The space guarantee can be set to one of the following:

    • None

      No space guarantee is configured for the volume.

    • File

      Full size of sparsely written files (for example, LUNs) is guaranteed.

    • Volume

      Full size of the volume is guaranteed.

    • Partial

      The FlexCache volume reserves space based on its size. If the FlexCache volume's size is 100 MB or more, the minimum space guarantee is set to 100 MB by default. If the FlexCache volume's size is less than 100 MB, the minimum space guarantee is set to the FlexCache volume's size. If the FlexCache volume's size is grown later, the minimum space guarantee is not incremented.

    Note

    The space guarantee is Partial when the volume is of type Data-Cache.

  • Details (Physical)

    Displays the physical characteristics of the volume.

  • Total Capacity

    Displays the total physical capacity in the volume.

  • Data Capacity

    Displays the amount of physical space used by the volume (used capacity) and the amount of physical space that is still available (free capacity) in the volume. These values are also displayed as a percentage of the total physical capacity.

    When the Thin-Provisioned Volume Space At Risk event is generated for thinly provisioned volumes, the amount of space used by the volume (used capacity) and the amount of space that is available in the volume but cannot be used (unusable capacity) because of aggregate capacity issues is displayed.

  • Snapshot Reserve

    Displays the amount of space used by the Snapshot copies (used capacity) and amount of space available for Snapshot copies (free capacity) in the volume. These values are also displayed as a percentage of the total snapshot reserve.

    When the Thin-Provisioned Volume Space At Risk event is generated for thinly provisioned volumes, the amount of space used by the Snapshot copies (used capacity) and the amount of space that is available in the volume but cannot be used for making Snapshot copies (unusable capacity) because of aggregate capacity issues is displayed.

  • Volume Thresholds

    Displays the following volume capacity thresholds:

    • Nearly Full Threshold

      Specifies the percentage at which a volume is nearly full.

    • Full Threshold

      Specifies the percentage at which a volume is full.

  • Other Details

    • Autogrow Max Size

      Displays the maximum size up to which the volume can automatically grow. The default value is 120% of the volume size on creation. This field is displayed only when autogrow is enabled for the volume.

      Displays the space reserved in the quotas.

    • Qtree Quota Overcommitted Capacity

      Displays the amount of space that can be used before the system generates the Volume Qtree Quota Overcommitted event.

    • Fractional Reserve

      Controls the size of the overwrite reserve. By default, the fractional reserve is set to 100, indicating that 100 percent of the required reserved space is reserved so that the objects are fully protected for overwrites. If the fractional reserve is less than 100 percent, the reserved space for all the space-reserved files in that volume is reduced to the fractional reserve percentage.

    • Snapshot Daily Growth Rate

      Displays the change (in percentage, or in KB, MB, GB, and so on) that occurs every 24 hours in the Snapshot copies in the selected volume.

    • Snapshot Days to Full

      Displays the estimated number of days remaining before the space reserved for the Snapshot copies in the volume reaches the specified threshold.

      The Snapshot Days to Full field displays a Not Applicable value when the growth rate of the Snapshot copies in the volume is zero or negative, or when there is insufficient data to calculate the growth rate.

    • Snapshot Autodelete

      Specifies whether Snapshot copies are automatically deleted to free space when a write to a volume fails because of lack of space in the aggregate.

    • Snapshot Copies

      Displays information about the Snapshot copies in the volume.

      The number of Snapshot copies in the volume is displayed as a link. Clicking the link opens the Snapshot Copies on a Volume dialog box, which displays details of the Snapshot copies.

      The Snapshot copy count is updated approximately every hour; however, the list of Snapshot copies is updated at the time that you click the icon. This might result in a difference between the Snapshot copy count displayed in the topology and the number of Snapshot copies listed when you click the icon.

  • Volume Move

    Displays the status of either the current or the last volume move operation that was performed on the volume, and other details, such as the current phase of the volume move operation which is in progress, source aggregate, destination aggregate, start time, end time, and estimated end time.

    • If the volume is a FlexGroup volume

    • If the volume is in a synchronous protection relationship

    • When the volume ID is unknown, for example, when you have a intercluster relationship and the destination cluster has not yet been discovered Clicking another volume in the topology selects and displays information for that volume. A question mark (Icon for HA state – unknown ) in the upper-left corner of a volume indicates that either the volume is missing or that it has not yet been discovered. It might also indicate that the capacity information is missing. Positioning your cursor over the question mark displays additional information, including suggestions for remedial action.

      The topology displays information about volume capacity, lag, Snapshot copies, and last successful data transfer if it conforms to one of several common topology templates. If a topology does not conform to one of those templates, information about volume lag and last successful data transfer is displayed in a relationship table under the topology.

Clearing the Capacity check box hides all capacity information for all volumes in the topology.

    • Lag

      Displays the lag duration and the lag status of the incoming protection relationships. Clearing the Lag check box hides all lag information for all volumes in the topology. When the Lag check box is dimmed, then the lag information for the selected volume is displayed in the relationship table below the topology, as well as the lag information for all related volumes.

    • Snapshot

      Displays the number of Snapshot copies available for a volume. Clearing the Snapshot check box hides all Snapshot copy information for all volumes in the topology. Clicking a Snapshot copy icon ( Icon for the list of Snapshot copies associated with a volume ) displays the Snapshot copy list for a volume. The Snapshot copy count displayed next to the icon is updated approximately every hour; however, the list of Snapshot copies is updated at the time that you click the icon. This might result in a difference between the Snapshot copy count displayed in the topology and the number of Snapshot copies listed when you click the icon.

    • Last Successful Transfer

      Displays the amount, duration, time, and date of the last successful data transfer. When the Last Successful Transfer check box is dimmed, then the last successful transfer information for the selected volume is displayed in the relationship table below the topology, as well as the last successful transfer information for all related volumes.

  • History

    Displays in a graph the history of incoming SnapMirror and SnapVault protection relationships for the selected volume. There are three history graphs available: incoming relationship lag duration, incoming relationship transfer duration, and incoming relationship transferred size. History information is displayed only when you select a destination volume. If you select a primary volume, the graphs are empty, and the message No data found is displayed.

    You can select a graph type from the drop-down list at the top of the History pane. You can also view details for a specific time period by selecting either 1 week, 1 month, or 1 year. History graphs can help you identify trends: for example, if large amounts of data are being transferred at the same time of the day or week, or if the lag warning or lag error threshold is consistently being breached, you can take the appropriate action. Additionally, you can click the Export button to create a report in CSV format for the chart that you are viewing.
