29.4.3 Creating Metro Mirror pairs
with TSO
In Example 29-12, we used the same paths that were created in 29.3.4, “Creating paths using
TSO” on page 446. We established a volume pair with Metro Mirror from the DS6000 to the
ESS 800.

29.4.4 Managing Global Copy pairs with the DS CLI
In this example, we show how you can establish Global Copy volume pairs between a
DS6000 and an ESS 800 with the DS CLI. We created a Global Copy pair. Volume 0603 from
the DS6000 is the source volume, and the target volume on the ESS is 0503.
In Example 29-13, we created a pair with the mkpprc command. Then, we listed the pair with
the lspprc command nand paused the pair with the pausepprc command.

29.5 Managing ESS 800 Global Mirror
The establishment of Global Mirror between a DS6000 and an ESS 800 is achieved using the
same methods as explained in Chapter 26, “Global Mirror examples” on page 341.
29.5.1 Managing Global Mirror pairs using the DS CLI
In Example 29-14 on page 452, we established a Global Copy pair between volume 0500 on
the ESS 800 and volume 0600 on the DS6000. Next, we created a FlashCopy on the remote
