This IBM® Redpaper™ publication describes the IBM Cascading FlashCopy® support introduced with the IBM DS8000® License Machine Code (LMC) Release 8.3 (LMC 8.8.30.xx.xx, bundle version 88.30.xxx.xx) or later.

The Cascading FlashCopy support enables a FlashCopy source device to become a FlashCopy source, or a FlashCopy target device to become a FlashCopy source.

This capability provides improvements to a range of Copy Services scenarios, but essentially enables the reversal of one of several FlashCopy relationships without first withdrawing the other relationships.

This publication explores a range of use cases, explaining the improvements and benefits of the Cascading FlashCopy.
