Table 112 Relevant Properties of RemoteStorageSynchronized (continued)
DescriptionProperties
• 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 HP 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 property called RoleReversed specifies whether the role of source and target element has
been reversed from its configured one due to the failover. If on a secondary 3PAR array the role
is reversed but the link is back up and volumes synced, CopyState will show Synchronized and
RoleReversed true.
Following is a table of the state transitions during disaster recovery after a primary 3PAR array
goes down.
