Listing the available ports using DS CLI
Having determined WWNN of the remote devices, we can now display the ports that are
available for establishing PPRC paths. In Example 29-7, we are logged on to the DS6000
using DS CLI, so the remote device is the ESS 800.
Note: When using the lsavailpprcport command, you must specify LSSs that actually
exist.
Example 29-7 Displaying available ports for PPRC path establishment
dscli> lsavailpprcport -remotedev IBM.2105-22399 -remotewwnn 5005076300C09517 06:05
Date/Time: 8 November 2005 23:13:47 IBM DSCLI Version: 5.1.0.204 DS: IBM.1750-1300247
Local Port Attached Port Type
=============================
I0003 I00AC
I0103 I000C
Note: When issuing commands that refer to an ESS 800, the ESS 800 serial number is
only five digits, and not the seven you see for the DS6000 or DS8000. So, in our examples,
the serial number syntax we use is IBM.2105-22399, not IBM.2105-1322399.
Establishing the logical paths using the 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 with the mkpprcpath command. You can
then display established paths using the lspprcpath command.
In Example 29-8, we established a single path between LSS 06 on the DS6000 and LSS 05
on the ESS 800 and then showed the paths available for LSS 06 on the DS6000.

In Example 29-9, we add an additional path between LSS 06 on the DS6000 and LSS 05 on
the ESS 800. Note that we include the existing path when creating a new path. Otherwise, the
existing path is removed and only the new path will be available for use.
