With the SmartIO feature, you can disable or enable caching for a volume or a mount point.
If automatic caching is configured, you do not need to explicitly enable caching for any data objects. The SmartIO feature caches all of the data objects of the same type as the cache area (VxVM or VxFS). The data objects have the caching state of auto, by default. If required, you can disable caching for a particular data object. If the system has an
auto cache area, the SmartIO feature caches any objects that have the auto state or the enabled state.
If automatic caching is not configured, you must explicitly enable caching for any data objects that you want the SmartIO feature to cache. If the system has a no-auto cache area, the SmartIO feature only caches the objects that have the enabled state. The SmartIO feature does not cache data objects with the caching state of auto, which is the default caching state.
