# SDS - Synchronizing Data

1. Review the Synchronization Rules.

2. Log into the System Administration tool of the primary (master) controller.

3. If required, start sharing the specified data from the local element with the selected element or elements at the required scope. See Sharing Data for instructions. Before you can perform a sync operation, the remote element must be sharing data with the local element at the desired scope.

4. Determine if shared forms are out of sync by comparing the form data on the local (master) controller with the form data on the remote (slave) controller. If there are only a few records in a couple of forms that are out of sync, you may want to synchronize the forms by making the programming updates manually on the remote nodes. You should also use the form comparison feature to determine if you should not synchronize specific data. See Comparing Forms for instructions.

5. If you are sharing device data between a resilient pair, compare the Single Line IP Sets forms, the Multiline IP Sets forms, and the Wireless IP Sets forms. By comparing these forms, you can determine if a directory number only exists on one of the controller pairs. If there are directory numbers that on ly appear on one controller and not the other, a synchronization operation will generate a large number of error logs. To prevent these error logs, correct any remote directory number inconsistencies before you perform a synchronization.

6. Go to the Network Elements form.

7. Click the check boxes beside the elements that you want to synchronize. The Sharing Data column identifies if the element has been configured to share data.

NOTES

- To select all the network elements in the list click the Select All box located in the top left-hand corner of the frame.

- You can sort the form records in ascending order based on the field type by clicking on the field header. If you click the Data Refresh button, the form records will be displayed in the original order.

8. Click Sync. The local system begins communicating with the elements that you selected for sharing. A confirmation window lists the elements that will be included in the synchronization and the forms that will be updated.

CAUTION: After you click Sync, if the local (master) node is unable to communicate with the remote node, the synchronization will be aborted. The remote node will wait approximately 15 minutes before it assumes that the local element is unreachable and begins to allow users to log into system tool sessions again. If there is a communication problem after the synchronization has started, SDS will wait up to 60 minutes before it aborts the synchronization attempt. During that time users will be unable to log in to the system tools.

9. Select the Synchronization Option:

10. Data Migration: Select this option if you are migrating 3300 ICP Release 6.x SDS-enabled systems to 3300 ICP Release 7.x software or later. A Data Migrate operation synchronizes the system data from the master controller to the slave controllers with the data overwrite and merge options set to the recommended defaults.

11. Data Repair: Select this option to repair data on a slave controller. The Data Repair operation overwrites all the shared data, including the user and device data, on the slave controller with the shared data from the master controller.

10. Select the forms that you want to synchronize:

- To select all forms for synchronization, check Synchronize All Shared Forms. All check boxes of the form groupings are automatically selected

- To select a subset of forms for synchronization, check the box of the form group or expand the group and check the forms within a specific grouping. If you check the box of a form group, all the forms within the group are checked.

- If you select the Device and User Data grouping, all the sub-forms in that group are selected for synchronization.

- A synchronization may fail or may generate update errors if you attempt to synchronize a single form or individual data entity that has data dependencies in other forms. To avoid sync failures or update errors caused by data dependencies, ensure that the forms that appear in the list above the checked form or data entity are in sync first.

11. Click Advanced to view and modify the synchronization properties

12. Select Overwrite to delete any system data on the slave that does not exist on the master

13. Select Merge to add any system data on slave controller that does not exist on the master controller to the master controller. Note that user and device data, with the exception of the User Authorization profile data, is always overwritten. By default, the User Authorization profile data is merged.

12. Set the Resilient User-Device Synchronization Policy (only presented if resilient form data is selected for sharing):

13. If you are performing a data migration select "Only Synchronize data where <local element> is the PRIMARY host for resilient devices".

14. If you are performing a data repair, select "Only Synchronize data where <local element> is the PRIMARY and SECONDARY host for resilient devices".

13. Click Apply. The Confirm Synchronization window opens.

14. Ensure that you have selected the correct forms for synchronization.

15. Click OK. A window opens that displays the progress of the synchronization operation.

If the IP address, System Name, or System Type are programmed incorrectly for any of the selected network elements, the system will detect and display the errors. If you receive an error, open the Network Elements form ( ), correct the errors, and then repeat the synchronization procedure.

NOTE: You may experience database inconsistencies. For example, if you add a controller that has directory numbers of resilient devices, and then perform a synchronization, the numbers may appear in only one database. To resolve this problem, see Correcting Inconsistent RDNs.

For synchronization with a MiCollab server:

- The STOP button, which allows you to cancel the operation at any moment, is not available.

- If errors or conflicts with data on MiCollab server are detected, the system creates a software log and displays an appropriate error message advising you to log into the MiCollab server and run the Reconcile Wizard. See the MiCollab documentation on the Mitel Customer documentation site (https://www.mitel.com/document-center/business-phone-systems/mivoice-business) for more information.
