Pin a Volume
NOTE: Before you pin a volume, the performance policy associated with
that volume must have caching enabled.
Pin the volume.
vol
--edit
volume_name
--cache_pinned
yes
If the volume can be pinned, you will see additional capacity
information for that volume. If the volume cannot be pinned, you may see a
"cache capacity exceeds available capacity" message.
Pinning a volume:
vol --edit volume1 --cache_pinned yes
