You may verify, with a last FlashCopy query, that the FlashCopy relationships are removed.
Example 26-30 illustrates this.

The ACT column with the number 1 indicates an active FlashCopy relationship. The 0 (zero) in
the FlashCopy query, after the FlashCopy withdraw command, indicates that the FlashCopy
relationship is removed.
26.5.5 Delete Global Copy volume pairs
Remove all Global Copy volume pair relationships. Example 26-31 on page 364 shows the
TSO commands that are used for this.
