PDFs
Once you have created ILM rules and an ILM policy, you can continue to work with them, modifying their configuration as your storage requirements change.
Deleting an ILM rule
To keep the list of current ILM rules manageable, delete any ILM rules that you are not likely to use.
-
You must be signed in to the Grid Manager using a supported browser.
-
You must have specific access permissions.
|
You cannot delete an ILM rule if it is currently used in the active policy or in the proposed policy. If you need to delete an ILM rule that is used a policy, you must perform these steps first:
|
-
Select ILM > Rules.
-
Review the table entry for the rule you want to remove.
Confirm that the rule is not used in the active ILM policy or the proposed ILM policy.
-
If the rule you want to remove is not in use, select the radio button and select Remove.
-
Select OK to confirm that you want to delete the ILM rule.
The ILM rule is deleted.
If you delete a rule that is used in a historical policy, an
icon appears for the rule when you view the policy, which indicates that the rule has become a historical rule.
Editing an ILM rule
You might need to edit an ILM rule to change a filter or placement instruction.
-
You must be signed in to the Grid Manager using a supported browser.
-
You must have specific access permissions.
You cannot edit a rule if it is being used in the proposed ILM policy or the active ILM policy. Instead, you can clone these rules and make any required changes to the cloned copy. You also cannot edit the stock ILM rule (Make 2 Copies) or ILM rules created before StorageGRID version 10.3.

|
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.
The ILM Rules page appears. This page shows all available rules and indicates which rules are being used in the active policy or the proposed policy.
-
Select a rule that is not being used, and click Edit.
The Edit ILM Rule wizard opens.
-
Complete the pages of the Edit ILM Rule wizard, following the steps for creating an ILM rule and using advanced filters, as necessary.
When editing an ILM rule, you cannot change its name.
-
Click Save.
If you edit a rule that is used in a historical policy, an
icon appears for the rule when you view the policy, which indicates that the rule has become a historical rule.
Cloning an ILM rule
You cannot 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 cannot clone an ILM rule if it was created using StorageGRID version 10.2 or earlier.

Viewing the ILM policy activity queue
You can view the number of objects that are in the queue to be evaluated against the ILM policy at any time. You might want to monitor the ILM processing queue to determine system performance. A large queue might indicate that the system is not able to keep up with the ingest rate, the load from the client applications is too great, or that some abnormal condition exists.
