Discarding Pinned Cache

If the controller loses access to one or more logical drives, the controller preserves the data from the logical drive. This preserved cache is called Pinned Cache. This cache is preserved until you import the logical drive or discard the cache. As long as there is pinned cache, you cannot perform certain operations on the logical drive.

ATTENTION  If foreign configurations exist, import the foreign configuration before you discard the pinned cache. Otherwise, you might lose data that belongs to the foreign configuration.

Perform the following steps to discard the pinned cache.

1.	Select More Actions > Discard Preserved Cache on the Controller dashboard.

NOTE  The Discard Preserved Cache option is displayed only if pinned cache is present on the controller.

A message appears, prompting you to confirm your choice.

2.	Select Confirm and click Yes, Discard.
