You can use the Volume / Health 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 Application Administrator or Storage Administrator role.
The command buttons enable you to perform the following tasks for the selected volume:
Enables you to add an alert to the selected volume.
Enables you to modify the threshold settings for the selected volume.
Enables you to annotate the selected volume.
Enables you to create either SnapMirror or SnapVault relationships for the selected volume.
Enables you to execute the following protection relationship operations:
Launches the Edit Relationship dialog box which enables you to change existing SnapMirror policies, schedules, and maximum transfer rates for an existing protection relationship.
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.
Temporarily disables scheduled updates for a selected relationship. Transfers that are already in progress must complete before the relationship is quiesced.
Breaks the relationship between the source and destination volumes and changes the destination to a read-write volume.
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.
Enables scheduled transfers for a quiesced relationship. At the next scheduled transfer interval, a restart checkpoint is used, if one exists.
Enables you to resynchronize a previously broken relationship.
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.
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.
Enables you to restore data from one volume to another volume.
Displays the data space that is consumed by the Snapshot copies.
Displays the space used by data in the volume.
Indicates that the space in the volume is nearly full. If this threshold is breached, the Space Nearly Full event is generated.
Indicates that the space in the volume is full. If this threshold is breached, the Space Full event is generated.
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.
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:
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.

No space guarantee is configured for the volume.
Full size of sparsely written files (for example, LUNs) is guaranteed.
Full size of the volume is guaranteed.
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.

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.
Displays the amount of space that can be used before the system generates the Volume Qtree Quota Overcommitted event.
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.
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.
Displays the estimated number of days remaining before the space reserved for the Snapshot copies in the volume reaches the specified threshold.
