Enabling or disabling the expiration lock

The expiration lock provides enhanced volume protection. Enabling the expiration lock ensures that read-only volumes and protect volumes cannot be changed to read/write volumes, even after the retention term ends. Disabling the expiration lock changes the access attribute to read/write after the retention term ends. This setting applies to all volumes in the storage system with the read-only and protect attribute.

Device Manager - Storage Navigator secondary windows must be defined for use in advance. When you select Modify from the Data Retention secondary window to enable or disable the expiration lock, other users or programs are prevented from changing storage system settings. When you close the secondary window, Modify mode is released. For more information about Device Manager - Storage Navigator secondary windows and Modify mode, see the Hitachi Device Manager - Storage Navigator User Guide.

Before you begin

The Storage Administrator (Provisioning) role is required to perform this task.

Procedure

  1. Click Actions Other Function Data Retention.

  2. Click to change to Modify mode.

  3. In the Data Retention window, verify which button appears beside Expiration Lock.

    • If Disable > Enable appears, go to the next step.

    • If Enable > Disable appears, expiration lock is already enabled. You do not need to follow the rest of this procedure because attempts to change access attribute to read/write are already prohibited.

  4. Click Disable > Enable. A confirmation message appears.

  5. Click OK. The button changes to Enable > Disable, and the expiration lock is enabled.

    When the expiration lock is enabled, the access attributes of volumes cannot be changed to read/write even after the retention term ends.

    To disable the expiration lock, click Enable > Disable. The access attribute can then be changed to read/write after the retention term ends.

  • Protecting volumes using Data Retention Utility

    After provisioning your system, you can assign access attributes to open-system volumes to protect the volumes against read, write, and copy operations and to prevent users from configuring LU paths and command devices. Data Retention Utility software is required to assign access attributes to volumes.
