Pin and Unpin a Volume
You can pin a volume to cache as part of the volume creation process, or you can pin an existing volume in the Data Storage page.
Note:
If you enable deduplication when creating a new volume, or if an existing volume had deduplication enabled, you cannot enable volume caching (pinning) for the volume.
Before you pin a volume, the performance policy associated with that volume must have caching enabled.
Procedure
- Go to .
- Check the name of the volume you want to pin or unpin.
- Click the pencil icon to edit the volume. The Edit Volume dialog opens.
- On the Edit Volume page, click Performance on the progress bar.
-
Perform one of the following two actions:
- To pin a volume, select Pinned in the Caching pane.
- To unpin a volume, select Normal (default).
- Click Save. If you tried to pin a volume and the volume can be pinned, you will see additional capacity information for that volume. If the volume cannot be pinned, you may see a "not enough cache in the pool" message. For more information, see Unable to Pin a Volume.
