2 IBM System Storage DS6000 Series: Copy Services with IBM System z
You can use either the IBM System Storage DS Storage Command-Line Interface, DS CLI,
or the IBM System Storage DS Storage Manager Copy Services Graphical User Interface,
DS GUI, to configure Copy Services.
It should be noted that:
All DS6000 installations require at least an Operating Equipment License (OEL) key to
operate. However, Copy Services functions can only be used where the appropriate
License Key is installed.
The key Copy Services license types are: OEL, Remote Mirror and Copy (RMC) or PPRC,
and Point-in-Time Copy (PTC) or FlashCopy.
The DS CLI replaces both the ESS CLI and the ESS Copy Services CLI.
The DS CLI can also be used for ESS 800 Copy Services, but not ESS configuration. For
ESS configuration you must continue to use the ESS Web Specialist or ESS CLI.
The DS CLI can invoke Remote Mirror relationships with ESS 800, if the ESS 800 is at
code level LIC 2.4.3.65 or above.
The DS CLI can be used in reusable scripts and provides a consistent interface for current
and planned System Storage products.
The DS CLI now invokes a Copy Services function directly rather than invoking a saved
task.
The DS GUI can only be used for one-time execution of a Copy Services operation; it
cannot save tasks.
