To Create a Database Device Mirror

1. Initiate a Mirror action against a database device. For more information see Initiating an object operation.
2. Use the following table as a guide to understanding and modifying settings in the Mirror wizard:

Step	Settings and tasks
Action Options	Displays the database device you selected and lets you work with the following settings:
	Mirror Name	Lets you specify the full path name of the database mirror device that is to be the secondary device.
	Serial Writes	Lets you specify whether serial writes to the devices are enforced
	Contiguous (VMS only)	If the mirror is a file rather than a device, this option forces the file to be created contiguously.
Dependencies	Lists referring and referenced objects potentially impacted by the change. For details, see Dependencies.
