Storage Volumes page in the Storage Systems view

The Storage Volumes page in the Storage Systems view enables you to obtain any information about the volumes available in your environment to be able to reclaim unused space.   

To access the page, in the TrueSight console navigation pane, click Capacity > Storage > Storage Systems, and in the Storage Systems page, click the Storage Volumes tab.

Metrics per storage volume are displayed in a tabular format.

By default, some columns are hidden. You can show or hide columns using the action menuthat is located next to the table title.

Each row in the table represents a storage volume and displays the following metrics:

Storage PoolName of the storage pool.Not applicableSP_CONTAINS_VOLUME
Volume TypeType of the volume.Not applicableST_VOLUME_TYPE
Volume Tiering PolicyTiering policy applied to the volume.Not applicableST_TIERING_POLICY
MappedIndicates whether the volume 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 volume.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 volume subscribed capacity that has been actually consumed by the host. Will be typically less than 100% for thin volumes. Will be exactly 100% for all traditional volumes. Can be greater than 100% when the storage system saves additional metadata that are not taken into account in the volume's capacity.Average on the latest dayST_VOLUME_CONSUMED_CAPACITY_PCT
