20.4.1 Define Global Copy paths
You can use the following commands to define and manage Global Copy paths.
lsavailpprcport
The lsavailablepprcport command displays the Fibre Channel ports, which can be used to
establish Global Copy paths, see Example 20-11.
Example 20-11 lsavilpprcport command
dscli> lsavailpprcport -l -dev IBM.1750-13AAGXA -remotedev IBM.1750-13AAVCA -remotewwnn

lspprcpath
The lspprcpath command shows you the defined paths from an LSS. Example 20-12 lists the
paths from LSS 16.

dscli> lspprcpath -dev IBM.1750-13AAGXA 16

mkpprcpath
With the mkpprcpath command, you can define paths between two LSSs. In Example 20-13,
we establish a path from 1750-13AAGXA/LSS 16/I/O port I0000 to 1750-13AAVCA/LSS 16/I/O
port I0100.
Example 20-13 mkpprcpath command
dscli> mkpprcpath -dev IBM.1750-13AAGXA -remotedev IBM.1750-13AAVCA -remotewwnn

rmpprcpath
The rmpprcpath command removes all paths between two LSSs; see Example 20-14 on
page 231.
