Managing InfoTier

The storage policy of a file pool changes with the data access frequency and service requirements. You can manage tiers, node pools, and file pool policies to meet ever-changing service requirements. This chapter will guide administrators through InfoTier management.

Renaming a Storage Tier

According to service requirements, you can rename a tier you have created.

  5. In the Success dialog box that is displayed, click OK.

Deleting a Storage Tier

Based on service requirements, you can delete a logical storage tier you have created. You can delete a tier only after you have deleted all the node pools in it.

Prerequisites

  5. Click OK.

Deleting a File Pool Policy

After a file pool policy is deleted, the file storage and migration rules specified by the policy become invalid, so data storage will not be controlled by the policy.

Prerequisites

  • A file pool policy has been configured but does not meet current service requirements.
  • You have logged in to the DeviceManager as an administrator that has the permission to view the file system structure. The following administrators have the permission:
    • Super administrator
    • Resource administrator
    • Administrator

Procedure

  2. Choose Provisioning > InfoTier > File Pool Policy.
  3. Select the file pool policy that you want to delete and click Delete.
  4. In the Confirm dialog box that is displayed, click OK.
  5. In the Success dialog box that is displayed, click OK.

Modifying the Priority of a File Pool Policy

The priorities of file pool policies determine the execution sequence of the policies.

Prerequisites

  • A file pool policy has been configured but does not meet current service requirements.
  • You have logged in to the DeviceManager as an administrator that has the permission to view the file system structure. The following administrators have the permission:
    • Super administrator
    • Resource administrator
    • Administrator
Impact on the System

Changing properties of file pool policies that fail to meet the service development requirements can ensure proper service operation.

Procedure

  1. Log in to DeviceManager.
  2. Choose Provisioning > InfoTier > File Pool Policy.
  3. Click Up or Down to move the location of a specified policy in the list.

    An upper location indicates a higher priority. If a file matches multiple file pool policies, the system performs the file pool policy with the highest priority.

    NOTE:

    File pool policies of the defaulpolicy type have the lowest priority.
