Chapter 5. Using TotalStorage Productivity Center for Replication on Windows 2003 231
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
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
