16. Use TPC-R on the primary host to restart the copying of the Cnt Ac-S copy pairs with the
HyperSwap attribute.
Cnt Ac-S copy pairs with the HyperSwap attribute are moved from the SWAPPING status to
the DUPLEX status.
Operation is returned to normal.
Operating procedure during a primary storage system failure (with no information
lost from memory)
The following are the operating procedures taken when a failure, with no information lost from
memory, occurs in the primary storage system.
Failover
The failover procedure taken when a failure, with no information lost from memory, occurs in the
primary storage system is the same as the failover procedure taken when a failure, with information
lost from memory, occurs in the primary storage system. See “Failover” (page 471).
Failback
1. Recover the primary storage system failure.
2. On the primary host, execute the YKDELETE command for Cnt Ac-J Z copy pairs that are
between the primary storage system and the remote storage system.
The Cnt Ac-J Z copy pairs that are between the primary storage system and the remote storage
system are moved to the SIMPLEX status.
