29.6.2 Creating an ESS 800 FlashCopy with the DS CLI
You must start the DS CLI and connect to the ESS 800. Then issue DS CLI commands as
usual. An example is shown in Example 29-15.
Example 29-15 Using DS CLI to create an ESS 800 FlashCopy

CMUC00140I rmflash: FlashCopy pair 0500:0501 successfully removed.
29.6.3 Creating a remote FlashCopy on an ESS 800 with the DS CLI
You can use the DS CLI to create a remote FlashCopy on an ESS 800 where the source
PPRC device is a DS6000. In Example 29-16, we connected to a DS6000. We created a
Metro Mirror pair from volume 0600 on the DS6000 to volume 0500 on the ESS 800. We then
created a remote FlashCopy on the ESS 800 between ESS 800 volumes 0500 and 0501,
using a conduit LSS to send the command. We then removed the remote FlashCopy.
Example 29-16 Creating a remote FlashCopy where the ESS 800 is the remote target
dscli> mkpprc -remotedev IBM.2105-22399 -type mmir 0600:0500

CMUC00173I mkremoteflash: Remote FlashCopy volume pair 0500:0501 successfully created. Use the
lsremoteflash command to determine copy completion.

CMUC00180I rmremoteflash: Removal of the remote FlashCopy volume pair 0500:0501 has been initiated
successfully. Use the lsremoteflash command to determine when the relationship is deleted.
You can also reverse the scenario. using the ESS 800 as the source machine in a PPRC pair
and then creating the remote FlashCopy on the DS6000.
