Modify Global Mirror session

Use this page to modify the volumes participating in the existing Global Mirror session.

Introduction

Note: You can add or remove only those LSSs that already exist in the Metro Mirror session and that have Global Copy relationships established. You cannot add a new LSS to the session, but you can add volumes from existing LSSs.

When you select volumes, you must identify the LSSs and volumes within those LSSs that are going to participate in the Global Mirror session:

Global Copy primary volumes at the local sites
Global Copy secondary volumes (FlashCopy source volumes) at the remote sites
FlashCopy target volumes at the remote sites
LSSs to be used to connect the master and subordinate storage units
