Resetting the ZDO Procedure

During the update with ZDO, you have a reset option provided that the cutover has not been performed.

Prerequisites

Make sure that phase REQ_ZDO_SYSTEM_BACKUP has not yet been passed.

Context

As long as the users were not rolled over to the bridge subsystem and the phase REQ_USER_ROLLOVER_PREP has not been passed, you can perform a reset during uptime processing as in the standard update procedure.

For more information, see in the SUM Guide the chapter Start of the navigation path Running the Software Update Manager Next navigation step Working with the SUM Tool Resetting the Update End of the navigation path .

However, if the user rollover to the bridge subsystem has already been performed and the phase REQ_USER_ROLLOVER_PREP is completed, the reset works in a two-step approach. If a system backup is performed (see also Backup Strategy for ZDO), the reset function is available until phase REQ_ZDO_SYSTEM_BACKUP.

To reset the procedure, proceed as follows. After finishing both steps, you can start another update using Software Update Manager.

Procedure

In the More menu, choose Reset and confirm the Resetting Procedure dialog with Yes.

The reset procedure removes all read-only restrictions for the bridge subsystem during uptime. After this removal, all read-only tables are writable again and users can continue with regular production operation.
When you continue with the reset procedure, the bridge subsystem is stopped and deleted.

Note

This step requires downtime because the bridge subsystem is stopped and deleted. You can push this downtime to the next regular downtime window according to your maintenance plan.
