Determining the DS8000 WWNN with the DS GUI
To determine the DS8000 WWNN with the DS GUI:
1. Click Real-time manager.
2. Click Manage hardware.
3. Click Storage images (not the Storage Unit).
4. Click in the Select column for the DS8000 Storage Image, and from the Select Action
menu, select Properties.
5. The DS8000 Storage Image WWNN is displayed in the subsequent properties panel.
Determining the DS8000 WWNN with the DS CLI
In Example 28-5 we show how to display the WWNN of a DS8000 Storage Image using the
lssi command.

Listing the available ports using the DS CLI
Having determined the remote devices WWNN, we can now display the ports that are
available to establish PPRC paths. In Example 28-6 we are logged onto the DS8000 using
DS CLI, so the remote device is the DS6000. We display ports available to establish paths
between LSS 14 on the DS8000 and LSS 18 on the DS6000.

Establishing the logical paths using DS CLI
Having determined which ports are available for each LSS pair that you wish to copy and
mirror between, you now establish a one-way path using the
mkpprcpath command. You can
then display established paths using the lspprcpath command.
In Example 28-7, we first established a single path between LSS 14 on the DS8000 and LSS
18 on the DS6000. We then displayed the paths available for LSS 14 on the DS8000.
Note: When using the lsavailpprcport command you must specify LSSs that actually
exist.
