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:

LUN

Name of the LUN.Not applicableNAME
NetApp SystemName of the NetApp System.Not applicableNETAPP_CONTAINS_LUN
AggregateName of the Aggregate.Not applicableAGGREGATE_CONTAINS_LUN
VolumeName of the Volume.Not applicableVOLUME_CONTAINS_LUN
MappedIndicates whether the LUN is mapped or unmapped.Not applicableST_VOLUME_MAPPED
Time Since Last ActivityNumber of days since the last read or write operation has been observed on the monitored LUN.Not applicableST_VOLUME_TIME_SINCE_LAST_ACTIVITY
Host Visible Capacity [GB] Amount of capacity exposed to the host (i.e. subscribed capacity) in Gigabytes.Not applicableST_VOLUME_HOST_VISIBLE_CAPACITY
Consumed Capacity [GB] Capacity actually consumed in Gigabytes.Average on the latest dayST_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 dayST_VOLUME_CONSUMED_CAPACITY_PCT
