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 includes a three-copies rule instead of a two-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 two-copies rule instead of a three-copies rule, the new policy will be marked as Active, but it will not take effect until all nodes are online and available.

Procedure

  1. When you are ready to activate a proposed policy, select the policy on the ILM Policies page and click Activate.
    A warning message is displayed, prompting you to confirm that you want to activate the proposed policy.

    Warning displayed before policy is activated
    Attention: A prompt appears in the warning message if the default rule for the policy does not retain objects forever. In this example, the retention diagram shows that the default rule will delete objects after 2 years. You must type 2 in the text box to acknowledge that any objects not matched by another rule in the policy will be removed from StorageGRID after 2 years.
