Additionally, you can use the details page to clone, edit, or remove a rule.
Clone an ILM rule
You can't edit a rule if it is being used in the proposed ILM policy or the active ILM policy. Instead, you can clone a rule and make any required changes to the cloned copy. Then, if required, you can remove the original rule from the proposed policy and replace it with the modified version. You can't clone an ILM rule if it was created using StorageGRID version 10.2 or earlier.
Before adding a cloned rule to the active ILM policy, be aware that a change to an object's placement instructions might cause an increased load on the system.
-
Select ILM > Rules.
-
Select the checkbox for the rule you want to clone, then select Clone. Alternatively, select the rule name, then select Clone from the rule details page.
-
Update the cloned rule by following the steps for editing an ILM rule and using advanced filters in ILM rules.
When cloning an ILM rule, you must enter a new name.
Edit an ILM rule
You might need to edit an ILM rule to change a filter or placement instruction.
You can't edit a rule if it is being used in the active ILM policy or the proposed ILM policy. Instead, you can clone these rules and make any required changes to the cloned copy. You also can't edit the system-provided rule, Make 2 Copies.
|
Before adding an edited rule to the active ILM policy, be aware that a change to an object's placement instructions might cause an increased load on the system. |
-
Select ILM > Rules.
-
Confirm that the rule you want to edit is not used in the active ILM policy or the proposed ILM policy.
-
If the rule you want to edit is not in use, select the checkbox for the rule and select Actions > Edit. Alternatively, select the name of the rule, then select Edit on the rule details page.
-
Complete the pages of the Edit ILM rule wizard. As necessary, follow the steps for creating an ILM rule and using advanced filters in ILM rules.
When editing an ILM rule, you can't change its name.
If you edit a rule that is used in a historical policy, the 
icon appears for the rule when you view the policy, which indicates that the rule has become a historical rule.
Remove an ILM rule
To keep the list of current ILM rules manageable, remove any ILM rules that you aren't likely to use.
To remove an ILM rule that is currently used in the active policy or in the proposed policy:
-
Clone the active policy or edit the proposed policy.
-
Remove the ILM rule from the policy.
-
Save, simulate, and activate the new policy to make sure objects are protected as expected.
To remove an ILM rule that is not currently used:
-
Select ILM > Rules.
-
Confirm that the rule you want to remove is not used in the active policy or the proposed policy.
-
If the rule you want to remove is not in use, select the rule and select Remove. You can select multiple rules and remove all of them at the same time.
-
Select Yes to confirm that you want to remove the ILM rule.
The ILM rule is removed.
If you remove a rule that is used in a historical policy, the icon appears for the rule when you view the policy, which indicates that the rule has become a historical rule.
View ILM metrics
You can view metrics for ILM, such as the number of objects in the queue and the evaluation rate. You can monitor these metrics to determine system performance. A large queue or evaluation rate might indicate that the system is not able to keep up with the ingest rate, the load from the client applications is excessive, or that some abnormal condition exists.
-
Select Dashboard > ILM.
Because the dashboard can be customized, the ILM tab might not be available. -
Monitor the metrics on the ILM tab.
