  • 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/TCMF/UR/URMF/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/TCMF, UR/URMF or GAD pair is created using the DP-VOL, or resynchronized. 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 TC/TCMF, UR/URMF or GAD pair using the DP-VOL is created.

  • Manage differential bitmaps in DP pool at pair create operations for 4TB or less TC/TCMF/UR/URMF/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/TCMF, UR/URMF or GAD pair is created using the DP-VOL.

  • Enable reboot of background service: Enable this option only when requested. If you enable this option, the SVP starts monitoring of the background service process (RMI-Server). When either of the followings exceeds its threshold value, the background service process for managing configuration information is restarted.

    • The amount of memory used in the background service process
    • 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.

Table. Advanced system settings No. 5, No. 6, No. 15, and No. 16
No. 5 No. 6 Description
Create operation Resync operation
Disabled Disabled Change the management method from hierarchical differences to SM differences. Change the management method from hierarchical differences to SM differences.
Enabled Change the management method from SM differences to hierarchical differences. The differential data management method is not changed.
Enabled Disabled Change the management method from SM differences to hierarchical differences. Change the management method from SM differences to hierarchical differences.
Enabled Change the management method from SM differences to hierarchical differences. The differential data management method is not changed.
Note: If the LDEV capacity exceeds 4 TB (for open)/262, 668 Cyl (for mainframe), it becomes the hierarchical memory management regardless of whether No. 5 and No. 6 are enabled.
No. 15 No. 16 Description
Disabled Disabled Even if a remote path failure is detected, the mirror is not split.
Enabled Disabled Even if a remote path failure is detected, the mirror is not split.
