Reclaiming Unused Storage Capacity 11.5.00

Over time, as servers connected to a SAN get decommissioned, administrators find an increasing number of unmapped volumes that are no longer used by any server. These volumes, while unused, still occupy disk space in the storage system. Being able to identify such unmapped volumes and reclaim the disk space uselessly consumed by these volumes will help administrators avoid unnecessary upgrades and extensions of their storage systems.

• • Identifying unmapped volumes
  • Identifying unused volumes

The following video (1:38) illustrates how you can use the Storage views to easily identify the unmapped and unused volumes that are allocated to decommissioned servers that can help you to reclaim unused storage capacity.

Identifying unmapped volumes

1. Access the Storage Systems page:
   1. Log on to the TrueSight console
   2. In the Navigation pane, click Capacity > Storage > Storage Systems
      
      
      
      
2. Click the Storage Volumes tab.
3. Display unmapped volumes:
   1. Click  next to No Mapped Filter and select Select Mapped Filter
   2. Select Not Mapped
   3. Click Apply. 
      

You can now reclaim the disk space uselessly consumed by these volumes to avoid unnecessary upgrades and extensions.

Identifying unused volumes

1. Access the Storage Systems page:
   1. Log on to the TrueSight console
   2. In the Navigation pane, click Capacity > Storage > Storage Systems
      
2. Click the Storage Volumes tab.
   
3. If needed, apply filters.
4. Apply a filter to the Time Since Last Activity column:
   1. Click the Time Since Last Activity column
   2. From the operator pull-down list, select equals.
   3. Type the number of days required (e.g.: 30).
   4. Click Filter.

The list of volumes that have not been used for 30 days is displayed. You can now take the necessary actions and reclaim the unused space.
