Edit Advanced System Settings window

• Hide alert information: The Alert window in the Device Manager - Storage Navigator main window is not displayed.
• Refresh forcibly after Apply: The configuration information for the storage system is forcibly updated after the configuration changes are applied to the storage system.
• Disable data polling: Polling stops.
• Disable retry of data updating: Retry does not take place even when you fail to acquire data.
• Enable Storage Navigator 2 All Function: The restrictions on login from Device Manager - Storage Navigator's login window are cleared, including the restrictions on the users who can log in and on the functions available after login. When enabling or disabling the advanced system setting, log in again.
• Manage differential bitmaps in DP pool at pair create and resync operations for 4TB or less TC/UR/GAD pairs: Differential data is maintained in a pool with which a DP-VOL that has the user capacity (up to 4,194,304 MB) is linked when a new TC/UR/GAD pair is created or resynchronized using the DP-VOL. Note that differential data is maintained, regardless of this setting, in a pool linked with the DP-VOL that has the user capacity (greater than 4,194,304 MB) when a new pair using the DP-VOL is created.

  • Time elapsed after the background service process is started
• Notify an alert when tier relocation is suspended by system: If you enable this option, when tier relocation is suspended by the system, an alert is issued to users. For details about an alert (SIM) to be issued, see the Troubleshooting chapter of the Provisioning Guide for Open Systems or Provisioning Guide for Mainframe Systems.
• Disable cache of the PP Info: Enable this option only when requested.

Change the management method from hierarchical differences to SM differences.

Change the management method from SM differences to hierarchical differences.

Note: If the LDEV capacity exceeds 4 TB (for open)/262,668 Cyl (for mainframe), the hierarchical memory management method is used regardless of whether advanced system settings 5 or 6 are enabled.
