Table 108 Relevant Properties of RemoteStorageSynchronized (continued)
DescriptionProperties
Specifies that groups that are in asynchronous periodic mode
should be periodically synchronized in accordance with the
SyncInterval
specified value of the replication. 0 means synchronization
will not happen unless it is done manually.
Specifies the policy of the Remote Copy volume groups for
dealing with I/O failure and error handling of the replication.
Valid values are:
SyncPolicy
• no_fail_wrt_on_err - Specifies that if Remote Copy is
started for the volume group and a write to the secondary
system fails, then the Remote Copy operation is stopped
and an I/O error is not returned to the host (default). This
allows the application writing the data to continue, but
makes the secondary volumes out of date with the primary
volumes.
• auto_recover - Specifies that if the Remote Copy is
stopped as a result of the Remote Copy links going down,
the group is restarted automatically after the links come
back up. If this policy is enabled for a group while the
group is stopped after link failures, it will be only be started
when the links come up for the failed target. If the links are
already up at the time the policy is set then the group will
not be restarted at that time.
• no_auto_recover - Specifies that if the Remote Copy is
stopped as a result of the Remote Copy links going down,
the group must be restarted manually after the links come
back up (default).
• over_per_alert - If a synchronization of a periodic
Remote Copy group takes longer to complete than its
synchronization period then an alert will be generated. This
is the default behavior.
• no_over_per_alert - If a synchronization of a periodic
Remote Copy group takes longer to complete than its
synchronization period then an alert will not be generated.
State Transition During Normal Operation
Table below shows the values of CopyState, SyncState and ProgressStatus for various CLI SyncStatus
of the volumes under normal environment. “Normal” means that the CLI Target Status field shows
“ready”.

State Transition During Disaster Recovery
If the primary 3PAR array goes down, the CLI Target Status field on the secondary 3PAR array will
show failed. CopyState on the secondary 3PAR array will show FailedOver only if role has
been reversed AND the link with original primary 3PAR array is down. A vendor extension Boolean
