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.
