Table 112 Relevant Properties of RemoteStorageSynchronized (continued)
DescriptionProperties
• Failing Back (12)
• Requires Activate (19)
RequestedCopyState is an integer enumeration that indicates
the last requested or desired state for the association. The
RequestedCopyState
actual state of the association is represented by CopyState.
Note that when CopyState reaches the requested state, this
property will be set to 'Not Applicable. If CopyState is Broken
or Skewed, this property will be set to “Synchronized”.
SyncType describes the intended outcome of the replication.
For remote replication, this property can only be Mirror (6),
which means create and maintain a copy of the source.
SyncType
CopyType describes the Replication Policy. Possible values
are:
CopyType
• Async (2)
• Sync (3)
ReplicaType provides information on how the Replica is being
maintained. For remote replication, this can only be “Full Copy
ReplicaType
(2)”, which indicates that a full copy of the source object is
(or will be) generated.
This property specifies whether the source, the target, or both
elements involved in a copy operation are undiscovered.
Possible values are:
UndiscoveredElement
• SystemElement (2)
• SyncedElement (3)
If either SystemElement or SyncedElement is undiscovered, the
corresponding property of the association will have object
path to a ReplicationEntity instead of StorageVolume. If neither
end is undiscovered, then this property is NULL.
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makes the secondary volumes out of date with the primary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).
