This concludes the steps through the GUI when you add copy sets to a Metro Mirror session.
This is a similar panel sequence when you add copy sets to other session types like Global
Mirror sessions or FlashCopy sessions.
TPC for Replication is going to be enhanced concerning volume selection which go into Copy
Sets to protect certain volumes which should never become a member of a Copy Set.
Note that Parallel Access Volumes, PAV, are not maintained in the TPC for Replication
database.
5.4.7 Add certain volumes to copy sets through the GUI
In order to keep it simple we built a test environment between two DS8000s and utilized only
a few volumes to show the principles of operations when working with TPC for Replication.
The idea is to replicate two volumes with Metro Mirror. Then create a FlashCopy relationship
between the Metro Mirror secondary volumes as FlashCopy source volumes and FlashCopy
target volumes in a different LSS. The FlashCopy may serve to create point-in-time
FlashCopies. This requires you to briefly freeze the Metro Mirror relationship in order to
achieve a consistent set of FlashCopy target volumes.
Figure 5-212 first shows the Metro Mirror test setup which we use for the Metro Mirror
example discussed here.
Figure 5-212 Metro Mirror volumes for session MM1
We created the MM1 session in 5.4.4, “Create a session using the GUI” on page 214. We
intend to use devices 00 and 01 in LSS 90 in DS8000 with serial number 20781 as Site 1
volumes and at Site 2 another DS8000, 03461, which holds the corresponding devices with

device number 00 and 01 in LSS A0. This is also what is reflected in Figure 5-212 on
page 231.
Figure 5-213 shows where to start when adding Copy Sets to session MM1. We click the
session hyper link which provides the session overview. The next step is to select an
appropriate action.
Opening the Action window starts an easy step-by-step approach to select the volumes which
are going to be defined to the session MM1.
Figure 5-213 Point to start to add Copy Sets to MM1 session
As Figure 5-214 shows we select Add Copy Sets which brings us to the next panel which
Figure 5-215 on page 233 displays.

In Figure 5-215 we define the Host 1 volumes. We select the Host 1 storage subsystem which
is the 20781 box. Within this box we select LSS 90 and then all volumes. Clicking Next brings
us to the next panel which Figure 5-216 on page 234 shows.
Figure 5-215 Choose Host 1 environment
In Figure 5-216 on page 234 we select the volume in Site 2. This is the Box 03461. As
Figure 5-212 on page 231 explains we want LSS A0 to hold the Metro Mirror secondary
volumes. Therefore, we select LSS A0 from the list. Host 2 volumes allows only all volumes
due to the previous selection for H1 volumes. Clicking Next displays all the matching copy
sets as Figure 5-217 on page 235 shows.

Figure 5-216 Choose Host 2 environment for session MM1
Actually Figure 5-217 on page 235 first displays all Copy Sets with a check mark indicating
that these Copy Sets are selected to be added to the TPC for Replication database. Currently
there is no un-select all button which would make it easy to un-select all Copy Sets first and
then just manually select the first two volumes which we want to be added to the Copy Set
MM1. In this particular case we removed the check mark from all Host 1 volumes except for
volume 00 and 01 respectively 9000 and 9001which we intend to include in the session MM1.
This is what Figure 5-217 on page 235 finally shows.
