452 IBM System Storage DS6000 Series: Copy Services with IBM System z
device. Then, we created session 20 for LSS 05. Finally, we created a Global Mirror using
session 20 and LSS 05.

29.6 Managing ESS 800 FlashCopy
If there is a FlashCopy license for the ESS 800, it is possible to manage ESS FlashCopy with
the DS CLI or DS GUI. The establishment of a FlashCopy pair on an ESS 800, using the DS
GUI, is no different than establishing a DS6000 FlashCopy pair (see 9.6, “FlashCopy
management using the DS SM” on page 87). The establishment of a FlashCopy pair on an
ESS 800 using the DS CLI is also no different (see 9.4, “Local FlashCopy using the DS CLI”
on page 73). In a situation where the ESS 800 is in a PPRC relationship, it is also possible to
create remote FlashCopies using the mkremoteflash command. In each case, creating,
changing, and removing the FlashCopy is done using the same commands.
