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

Switch to Performance View

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

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 volumes that are in synchronous protection relationships.

View Volumes

Enables you to navigate to the Health: All Volumes view.

Summary

Displays SnapMirror and SnapVault relationships properties for a selected volume. For any other relationship type, only the Relationship Type property is displayed. If a primary volume is selected, only the Managed and Local Snapshot copy Policy are displayed. Properties displayed for SnapMirror and SnapVault relationships include the following:

• Source Volume

  Displays the name of the selected volume's source if the selected volume is a destination.

• Lag Status

  Displays the update or transfer lag status for a protection relationship. The status can be Error, Warning, or Critical.

  The lag status is not applicable for synchronous relationships.

• Lag Duration

  Displays the time by which the data on the mirror lags behind the source.

• Last Successful Update

  Displays the date and time of the most recent successful protection update.

  The last successful update is not applicable for synchronous relationships.

• Storage Service Member

  Displays either Yes or No to indicate whether or not the volume belongs to and is managed by a storage service.

• Version Flexible Replication

  Displays either Yes, Yes with backup option, or None. Yes indicates that SnapMirror replication is possible even if source and destination volumes are running different versions of ONTAP software. Yes with backup option indicates the implementation of SnapMirror protection with the ability to retain multiple versions of backup copies on the destination. None indicates that Version Flexible Replication is not enabled.

• Relationship Capability

  Indicates the ONTAP capabilities available to the protection relationship.

• Protection Service

  Displays the name of the protection service if the relationship is managed by a protection partner application.

• Relationship Type

  Displays any relationship type, including Asynchronous Mirror, Asynchronous Vault, Asynchronous MirrorVault, StrictSync, and Sync.

• Relationship State

  Displays the state of the SnapMirror or SnapVault relationship. The state can be Uninitialized, SnapMirrored, or Broken-Off. If a source volume is selected, the relationship state is not applicable and is not displayed.

• Transfer Status

  Displays the transfer status for the protection relationship. The transfer status can be one of the following:

  • Aborting

    SnapMirror transfers are enabled; however, a transfer abort operation that might include removal of the checkpoint is in progress.

  • Checking

    The destination volume is undergoing a diagnostic check and no transfer is in progress.

  • Finalizing

    SnapMirror transfers are enabled. The volume is currently in the post-transfer phase for incremental SnapVault transfers.

  • Idle

    Transfers are enabled and no transfer is in progress.

  • In-Sync

    The data in the two volumes in the synchronous relationship are synchronized.

  • Out-of-Sync

    The data in the destination volume is not synchronized with the source volume.

  • Preparing

    SnapMirror transfers are enabled. The volume is currently in the pre-transfer phase for incremental SnapVault transfers.

  • Queued

    SnapMirror transfers are enabled. No transfers are in progress.

  • Quiesced

    SnapMirror transfers are disabled. No transfer is in progress.

  • Quiescing

    A SnapMirror transfer is in progress. Additional transfers are disabled.

  • Transferring

    SnapMirror transfers are enabled and a transfer is in progress.

  • Transitioning

    The asynchronous transfer of data from the source to the destination volume is complete, and the transition to synchronous operation has started.

  • Waiting

    A SnapMirror transfer has been initiated, but some associated tasks are waiting to be queued.

• Max Transfer Rate

  Displays the maximum transfer rate for the relationship. The maximum transfer rate can be a numerical value in either kilobytes per second (Kbps), Megabytes per second (Mbps), Gigabytes per second (Gbps), or Terabytes per second (Tbps). If No Limit is displayed, the baseline transfer between relationships is unlimited.

• SnapMirror Policy

  Displays the protection policy for the volume. DPDefault indicates the default Asynchronous Mirror protection policy, XDPDefault indicates the default Asynchronous Vault policy, and DPSyncDefault indicates the default Asynchronous MirrorVault policy. StrictSync indicates the default Synchronous Strict protection policy, and Sync indicates the default Synchronous policy. You can click the policy name to view details associated with that policy, including the following information:

  • Transfer priority
  • Ignore access time setting
  • Tries limit
  • Comments
  • SnapMirror labels
  • Retention settings
  • Actual Snapshot copies
  • Preserve Snapshot copies
  • Retention warning threshold
  • Snapshot copies with no retention settings

  In a cascading SnapVault relationship where the source is a data protection (DP) volume, only the rule sm_created applies.

• Update Schedule

  Displays the SnapMirror schedule assigned to the relationship. Positioning your cursor over the information icon displays the schedule details.

• Local Snapshot Policy

  Displays the Snapshot copy policy for the volume. The policy is Default, None, or any name given to a custom policy.

Views

Displays the protection topology of the selected volume. The topology includes graphical representations of all volumes that are related to the selected volume. The selected volume is indicated by a dark gray border, and lines between volumes in the topology indicate the protection relationship type. The direction of the relationships in the topology are displayed from left to right, with the source of each relationship on the left and the destination on the right.

Double bold lines specify an Asynchronous Mirror relationship, a single bold line specifies an Asynchronous Vault relationship, double single lines specify an Asynchronous MirrorVault relationship, and a bold line and non-bold line specifies a Synchronous relationship. The table below indicates if the Synchronous relationship is StrictSync or Sync.

Right-clicking a volume displays a menu from which you can choose either to protect the volume or restore data to it. Right-clicking a relationship displays a menu from which you can choose to either edit, abort, quiesce, break, remove, or resume a relationship.

The menus will not display in the following instances:

• If RBAC settings do not allow this action, for example, if you have only operator privileges
• If the volume is in a synchronous protection relationship
• When the volume ID is unknown, for example, when you have an 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 ( ) 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. In that case, the highlighted row in the table indicates the selected volume, and, in the topology view, bold lines with a blue dot indicate the relationship between the selected volume and its source volume.

Topology views include the following information:

• Capacity

  Displays the total amount of capacity used by the volume. Positioning your cursor over a volume in the topology displays the current warning and critical threshold settings for that volume in the Current Threshold Settings dialog box. You can also edit the threshold settings by clicking the Edit Thresholds link in the Current Threshold Settings dialog box. 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 ( ) 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.

Protection history graphs display the following information:

Relationship Lag Duration

Displays seconds, minutes, or hours on the vertical (y) axis, and displays days, months, or years on the horizontal (x) axis, depending on the selected duration period. The upper value on the y axis indicates the maximum lag duration reached in the duration period shown in the x axis. The horizontal orange line on the graph depicts the lag error threshold, and the horizontal yellow line depicts the lag warning threshold. Positioning your cursor over these lines displays the threshold setting. The horizontal blue line depicts the lag duration. You can view the details for specific points on the graph by positioning your cursor over an area of interest.

Relationship Transfer Duration

Displays seconds, minutes, or hours on the vertical (y) axis, and displays days, months, or years on the horizontal (x) axis, depending on the selected duration period. The upper value on the y axis indicates the maximum transfer duration reached in the duration period shown in the x axis. You can view the details of specific points on the graph by positioning your cursor over the area of interest.

Note: This chart is not available for volumes that are in synchronous protection relationships.

Relationship Transferred Size

Displays bytes, kilobytes, megabytes, and so on, on the vertical (y) axis depending on the transfer size, and displays days, months, or years on the horizontal (x) axis depending on the selected time period. The upper value on the y axis indicates the maximum transfer size reached in the duration period shown in the x axis. You can view the details for specific points on the graph by positioning your cursor over an area of interest.

Note: This chart is not available for volumes that are in synchronous protection relationships.

History area

The History area displays graphs that provide information about the capacity and space reservations of the selected volume. Additionally, you can click the Export button to create a report in CSV format for the chart that you are viewing.

Graphs might be empty and the message No data found displayed when the data or the state of the volume remains unchanged for a period of time.

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 the volume usage is consistently breaching the Nearly Full threshold, you can take the appropriate action.

History graphs display the following information:

Volume Capacity Used

Displays the used capacity in the volume and the trend in how volume capacity is used based on the usage history, as line graphs in bytes, kilobytes, megabytes, and so on, on the vertical (y) axis. The time period is displayed on the horizontal (x) axis. You can select a time period of a week, a month, or a year. You can view the details for specific points on the graph by positioning your cursor over a particular area. You can hide or display a line graph by clicking the appropriate legend. For example, when you click the Volume Used Capacity legend, the Volume Used Capacity graph line is hidden.

Volume Capacity Used vs Total

Displays the trend in how volume capacity is used based on the usage history, as well as the used capacity, total capacity, and details of the space savings from deduplication and compression, as line graphs, in bytes, kilobytes, megabytes, and so on, on the vertical (y) axis. The time period is displayed on the horizontal (x) axis. You can select a time period of a week, a month, or a year. You can view the details for specific points on the graph by positioning your cursor over a particular area. You can hide or display a line graph by clicking the appropriate legend. For example, when you click the Trend Capacity Used legend, the Trend Capacity Used graph line is hidden.

Volume Capacity Used (%)

Displays the used capacity in the volume and the trend in how volume capacity is used based on the usage history, as line graphs, in percentage, on the vertical (y) axis. The time period is displayed on the horizontal (x) axis. You can select a time period of a week, a month, or a year. You can view the details for specific points on the graph by positioning your cursor over a particular area. You can hide or display a line graph by clicking the appropriate legend. For example, when you click the Volume Used Capacity legend, the Volume Used Capacity graph line is hidden.

Snapshot Capacity Used (%)

Displays the Snapshot reserve and Snapshot warning threshold as line graphs, and the capacity used by the Snapshot copies as an area graph, in percentage, on the vertical (y) axis. The Snapshot overflow is represented with different colors. The time period is displayed on the horizontal (x) axis. You can select a time period of a week, a month, or a year. You can view the details for specific points on the graph by positioning your cursor over a particular area. You can hide or display a line graph by clicking the appropriate legend. For example, when you click the Snapshot Reserve legend, the Snapshot Reserve graph line is hidden.
