28.6 Managing DS6000 and DS8000 FlashCopy
The establishment of a FlashCopy pair on a DS6000 using the DS8000 DS GUI is no different
than establishing a DS8000 FlashCopy pair (see 9.6, “FlashCopy management using the DS
SM” on page 87. The establishment of a FlashCopy pair on a DS8000 using the DS6000 DS
GUI, is again no different than establishing a DS6000 FlashCopy pair. For the DS CLI, you
connect directly to the relevant SMC or HMC, so it is also not different.
28.6.1 Creating a remote FlashCopy on an DS6000 using DS CLI
It is also possible to use DS CLI to create a remote FlashCopy on a DS6000 where the
source PPRC device is a DS8000 and vice versa. In Example 28-12, we connected to a
DS8000 using the DS CLI. We determined that there are established paths from LSS 08 on
the DS8000 to LSS 06 on the DS6000. We created a Metro Mirror pair from volume 0801 on
