You must determine whether you want to modify your caching policy.

In most cases, the default caching policy of auto is the best caching policy that you can use. The caching policy should be changed only if a different policy provides better performance for your workload. Configuring the wrong caching policy can severely degrade volume performance; the performance degradation could increase gradually over time. You should use caution when modifying caching policies. If you experience performance issues with a volume for which the caching policy has been changed, you should return the caching policy to auto.

The following example modifies the caching policy of a volume named “vol2” to the policy none:

volume modify -volume vol2 -caching-policy none
