Unable to Pin a Volume

If you try to pin a volume and receive a "cache capacity exceeds available capacity" message, you have insufficient usable cache to pin the volume. There are two options:

  • Use another pool - you can use the array OS to display a list of other pools with sufficient cache. You have the option to switch your volume to that pool.
  • Unpin other pinned volumes - you can view the pinning capacity of other volumes by hovering over their names listed on the Caching dialog. A tooltip is displayed with the pinning capacity information for that volume. If your volume is already pinned but you want to free more usable cache, you can use the Caching facet on the volume's information page to view a list of pinned volumes.
