Figure 24-11 ICKDSF - define Global Mirror session
Example 24-27 shows an ICKDSF job that defines a Global Mirror session involving the LSS
that volume RS7000 belongs to. Note that with this Global Mirror command, you do not need
to define an LSS number, nor a CCA, nor the SSID.

Example 24-27 points again to an online volume by the DDNAME parameter. A session is
created involving the corresponding LSS; it is session number 001 in this example.

24.5.6 Add volumes to a session

In this step we add Global Copy primary volumes to the Global Mirror session; see
Figure 24-12 on page 320.
