When an alternate CF is available, the structure might be able to be rebuilt from the failed CF to an alternate CF. The possible results of the rebuild consist of the following:

• All structures successfully rebuild into the alternate CF. See All structures rebuild.
• Some structures are not rebuilt into the alternate CF. See Some structures do not rebuild.
• Structures in the failed CF become persistent or structure connections become failed-persistent. See Structure or connection persistence occurs.
• Structure rebuild fails to complete. See Structure rebuild fails.
• Structures cannot be rebuilt because there are storage constraints in the alternate CF. See Coupling facility storage constraints exist.
