“Operating procedure
during a primary An operation example
when the primary During a primary
storage system failure 6
storage system failure storage system stops (with no information
lost from memory)
(with no information due to a failure, with
lost from memory)”
(page 476) no information lost
from memory. After a
HyperSwap is
executed, a delta
resync is performed.
“Operating procedure
during a local storage An operation example
when the local storage During a local storage
system failure (with 7
system failure (with system stops due to a information lost from
memory)
information lost from
memory)” (page 485) failure, with
information lost from
memory. This
procedure uses TPC-R
to stop Cnt Ac-S Z
copy pairs with the
HyperSwap attribute,
and then recovers the
failure.
“Operating procedure

when the local storage During a local storage
system failure (with no 8
system failure (with no system stops due to a information lost from

information lost from
memory)” (page 487) failure, with no
information lost from
memory. This
procedure uses TPC-R
to stop Cnt Ac-S Z
copy pairs with the
HyperSwap attribute,
and then recovers the
failure.
“Operating procedure
during remote storage An operation example
when the remote During a remote
storage system failure 9
system failure (with storage system stops (with information lost
from memory)
information lost from
memory)” (page 487) due to a failure, with
information lost from
memory. Recover from
the failure, and then
resynchronizes the Cnt
Ac-J Z copy pairs.
“Operating procedure

when the remote During a remote
storage system failure 10
storage system failure storage system stops (with no information
lost from memory)
(with no information due to a failure, with
lost from memory)”
(page 490) no information lost
from memory. Recover
from the failure, and
then reconfigures the
Cnt Ac-J Z copy pairs
after first dissolving
them and canceling
their delta resync
standby statuses.
