Recalling Data to the Data Fabric File System
Prerequisites
- You must be a fabric manager or a fabric user to perform this operation.
- Data tiering must have been enabled on the volume during the volume creation, to be able to offload/recall data.
- Offloaded data must be present on the cold tier.
About this task
When you read data that has been offloaded to a remote target (or cold tier), data is automatically recalled to the file system to allow the read to succeed.
The recalled data is automatically:
- Purged based on the expiration time period set at the volume level for recalled data if there are no changes (for example, read operation).
- Offloaded based on the rule and the expiration time period set at the volume level for recalled data if there are changes (for example, overwrite operation).
For a cold tiering volume, you must explicitly recall the volume before running any analytics jobs.
Follow the steps given below to recall data manually from a volume to a cold tier.
Procedure
- Log on to the Data Fabric UI.
- Select Fabric user on the Home Page.
- Click the Table view icon on the Resources card. In the tabular list of fabrics, click the down arrow for the fabric that contains the volume.
- Click the ellipsis under Actions for the required volume.
- Select Recall data.
