Activating the ILM policy

After you add ILM rules to a proposed ILM policy, simulate the policy, and confirm it behaves as you expect, you are ready to activate the proposed policy.

Before you begin

About this task

When you activate an ILM policy, the system distributes the new policy to all nodes. However, the new active policy might not actually take effect until all grid nodes are available to receive the new policy. In some cases, the system waits to implement a new active policy to ensure that grid objects are not accidentally removed.
  • If you make policy changes that increase data redundancy or durability, those changes are implemented immediately. For example, if you activate a new policy that uses a Make 3 Copies rule instead of a Make 2 Copies rule, that policy will be implemented right away because it increases data redundancy.
  • If you make policy changes that could decrease data redundancy or durability, those changes will not be implemented until all grid nodes are available. For example, if you activate a new policy that uses a Make 2 Copies rule instead of a Make 3 Copies rule, the new policy will be marked as "Active," but it will not take effect until all nodes are online and available.

Steps
