Failover
1. From the local site, execute the YKSUSPND REVERSE command for the Cnt Ac-S Z copy group
container.
If you specify a route list that includes the primary site when executing the YKLOAD command,
an I/O error might occur during execution of the YKQUERY or YKEWAIT command. To prevent
this I/O error, specify a route list that does not include the primary site when executing the
YKLOAD
command.

2. Start operation at the local site.
You can start operation before executing the YKRESYNC DELTAJNL command, but the
following note applies: The time required for the status of the local-to-remote Cont AC-J Z copy
pair to change to DUPLEX increases according to the amount of data updated from the local
site after executing the YKRESYNC DELTAJNL command.
