374 IBM System Storage DS6000 Series: Copy Services with IBM System z
26.9.1 Create paths
When using the DS Storage Manager to create paths between two LSSs on two different
Storage Images, it is necessary to go through a six-step process creation wizard. This wizard
needs to be repeated for each data path to be defined. Remember that you have to define
paths between site 1 and site 2, for Global Copy replication, and eventually you will also have
to define paths within site 1 if the Master and Subordinates are on different Storage images.
To launch this wizard, first you need to go to the Paths panel under the Copy Services menu
of the DS Storage Manager GUI. In the Select Action pull-down list, choose
Create to
proceed with the first step of the wizard. See Figure 26-8.

The creation wizard then displays the “Select source LSS” panel; see Figure 26-9. Here you
select from the pull-down lists the
Storage complex, then the Storage unit, then the
Storage Image, and finally the LSS that contains the source volumes of the Global Copy
pairs. These are the volumes that are going to be members of the Global Mirror session.
