In Example 28-8, we added an additional path between LSS 14 on the DS8000 and LSS 18
on the DS6000. Not that we included the existing path when creating a new path. Otherwise
the existing path is removed and only the new path will be available for use.

To establish paths where the DS6000 is the source, connect to the DS6000 with the DS CLI
and follow the same process, but specify the DS8000 as the remote device.
28.3.4 Path creation using TSO
In Example , we established Metro Mirror paths from a DS6000 to a DS8000 with a TSO
command. CESTPATH commands
/* ------------------------------------------------------------------ */
/* */
/* ISSUE PPRC CESTPATH TO ESTABLISH PPRC PATHS */
/* */
/* ------------------------------------------------------------------ */
CESTPATH DEVN(X'E200') PRIM(X'6000' 500507630EFFFE16 X'06') -
SEC(X'2105' 5005076303FFC08F X'05') -
LINK(X'00030003' X'01030103') -
CGROUP(NO)
/* ------------------------------------------------------------------ */
Important: When you connect using the DS CLI to the DS8000 HMC, the DS8000 is the
local device and the DS6000 is the remote device. If you connect with the DS CLI to the
DS6000, then the DS6000 is now the local device and the DS8000 is the remote device.
Attention: The rmpprcpath command removes all paths between the source and target
LSSs. To just reduce the path count, use the mkpprcpath command and specify only the
paths you wish to continue using.
