LUNs page in the NetApp Systems view
The LUNs page in the NetApp Systems view enables you to obtain any information about the LUNs available in your environment to be able to reclaim unused space.
To access the page, in the TrueSight console navigation pane, click Capacity > Storage > NetApp Systems, and in the NetApp Systems page, click the LUNs tab.
Metrics per LUN are displayed in a tabular format. Each row in the table represents a LUN and displays the following metrics:
|Name of the LUN.||Not applicable||NAME|
|NetApp System||Name of the NetApp System.||Not applicable||NETAPP_CONTAINS_LUN|
|Aggregate||Name of the Aggregate.||Not applicable||AGGREGATE_CONTAINS_LUN|
|Volume||Name of the Volume.||Not applicable||VOLUME_CONTAINS_LUN|
|Mapped||Indicates whether the LUN is mapped or unmapped.||Not applicable||ST_VOLUME_MAPPED|
|Time Since Last Activity||Number of days since the last read or write operation has been observed on the monitored LUN.||Not applicable||ST_VOLUME_TIME_SINCE_LAST_ACTIVITY|
|Host Visible Capacity [GB]||Amount of capacity exposed to the host (i.e. subscribed capacity) in Gigabytes.||Not applicable||ST_VOLUME_HOST_VISIBLE_CAPACITY|
|Consumed Capacity [GB]||Capacity actually consumed in Gigabytes.||Average on the latest day||ST_VOLUME_CONSUMED_CAPACITY|
|Consumed Capacity [%]||Percentage of the LUN subscribed capacity that has been actually consumed by the host. Will be typically less than 100% for thin LUNs. Will be exactly 100% for all traditional LUNs. Can be greater than 100% when the NetApp system saves additional metadata that are not taken into account in the LUN's capacity.||Average on the latest day||ST_VOLUME_CONSUMED_CAPACITY_PCT|
To view details for a specific LUN
To view the details page for a particular LUN, click its (hyper-linked) name under the LUN column.
The details page displays information for the selected LUN under the following sections or panels:
|Section or Panel||Description|
A quick summary of all the capacity and traffic information available for the LUN.
|Configuration Details page||Configuration information about the LUN. The information displayed in this page depends on the configuration data metrics available in the entity. They are described in the ETL User Documentation.|
To find a specific NetApp System
Use the sorting and filtering options on the page to find a specific NetApp System.For more information, see Sorting a table in the TrueSight console and Using filtering options in views in the TrueSight console.
To find mapped or unmapped LUNs
Use the sorting and filtering options on the page to find mapped or unmapped LUNs. For more information, see Sorting a table in the TrueSight console and Using filtering options in views in the TrueSight console.
