Recall queue

The Recall Queue panel of the management interface displays the list of virtual volumes in the recall queue. You can use this panel to promote a virtual volume or filter the contents of the table.

A recall of a virtual volume retrieves the virtual volume from a physical cartridge and places it in the cache. A queue is used to process these requests. Virtual volumes in the queue are classified into three groups:
  • In Progress
  • Scheduled
  • Unscheduled
Unscheduled volumes are identified in the table according to a number that represents their position in the queue.

Column Name Description
Position The position of the virtual volume in the recall queue. Possible values are:
In Progress
A recall is in progress for the volume.
Scheduled
The volume is scheduled to be recalled. If optimization is enabled, the TS7700 will schedule recalls to be processed from the same physical cartridge.
Position
A number that represents the volume's current position in the list of volumes that have not yet been scheduled.
These unscheduled volumes can be promoted using the Action menu.
Virtual Volume The virtual volume to be recalled.
Physical Cartridges The serial number of the physical cartridge that the virtual volume resides on. If the virtual volume is distributed across two physical cartridges, both cartridge numbers are displayed separated by a comma.
This column can be hidden.
Time in Queue Length of time the virtual volume has been in the queue, displayed in hours, minutes, and seconds as HH:MM:SS.
This column can be hidden.
You can change the appearance of the Recall Queue table.
