The following explanations apply to the examples shown in Example 9-6:

Example 1: reverse a FlashCopy relationship.

In this example, three FlashCopy relationships are created with the

-record

and

-persist

parameters. The

reverseflash

commands are executed using a different sequence

number, which overwrites the one of the current FlashCopy relationship.

The

reverseflash

for the 0001:0101 and 0005:0105 relationships take place using the

-record

and

-persist

parameters. Because the two parameters are omitted for the

0003:0103 FlashCopy relationship, the two properties Recording and Persistent change to
disabled for this FlashCopy relationship. This terminates the 0003:0103 FlashCopy
relationship as soon it is successfully reversed.
