An operation example Operating procedure
when the primary during a primary
storage system stops storage system failure
due to a nonvolatile (nonvolatile) on page
failure. After a 8-82
HyperSwap is
executed, a delta
resync is performed.
An operation example Operating procedure
when the local storage during a local storage
system stops due to a system failure (volatile)
volatile failure. This on page 8-91
procedure uses TPC-R
to stop Cnt Ac-S Z
copy pairs with the
HyperSwap attribute,
and then recovers the
failure.
An operation example Operating procedure
when the local storage during a local storage
system stops due to a system failure
nonvolatile failure. (nonvolatile) on page
This procedure uses 8-93
TPC-R to stop Cnt Ac-S
Z copy pairs with the
HyperSwap attribute,
and then recovers the
failure.
An operation example Operating procedure
when the remote during remote storage
storage system stops system failure (volatile)
due to a volatile on page 8-93
failure. Recover from
the failure, and then
resynchronizes the Cnt
Ac-J Z copy pairs.
An operation example Operating procedure
when the remote during a remote
storage system stops storage system failure
due to a nonvolatile (nonvolatile) on page
failure. Recover from 8-96
the failure, and then
reconfigures the Cnt
Ac-J Z copy pairs after
first dissolving them
and canceling their
delta resync standby
statuses.
