Failing over the replication session changes the role of the destination system. After a failover, the original destination system becomes the source system, and production access is enabled for hosts and applications for recovery. Failovers can be planned or unplanned. Planned failovers are issued from the source system and are indicated by setting the is_planned parameter to true. When you fail over a replication session from the source system, the destination system is fully synchronized with the source to ensure that there is no data loss. During a planned failover, stop I/O operations for any applications and hosts. If a synchronization error occurs during a planned failover, the replication session enters the System_Paused state. You cannot pause a replication session during a planned failover. The following operations can be performed during planned failover: • Unplanned failover • Delete the replication session by removing the protection policy on the storage resource After a planned failover, the replication session is in an inactive state. You can use the reprotect action to synchronize the destination storage resource, and then resume the replication session. The auto-reprotect feature can also be used after a planned failover by using the reverse parameter, which activates the session in the reverse direction. Unplanned failures are events such as source system failure or an event on the source system that leads to downtime for production access. Unplanned failovers are issued from the destination system, and are indicated by setting the is_planned parameter to false. Unplanned failovers provide production access to the original 182

failover
Fail over a replication session instance. Failing over the replication session changes the role of the
destination system. After a failover, the original destination system becomes the source system, and
production access is enabled for hosts and applications for recovery. Failovers can be planned or
unplanned.
Planned failovers are issued from the source system and are indicated by setting the is_planned
parameter to true. When you fail over a replication session from the source system, the destination
system is fully synchronized with the source to ensure that there is no data loss. During a planned
failover, stop I/O operations for any applications and hosts. If a synchronization error occurs
during a planned failover, the replication session enters the System_Paused state. You cannot pause
a replication session during a planned failover. The following operations can be performed during
planned failover:
Unplanned failover
Delete the replication session by removing the protection policy on the storage resource
After a planned failover, the replication session is in an inactive state. You can use the reprotect
action to synchronize the destination storage resource, and then resume the replication session.
The auto-reprotect feature can also be used after a planned failover by using the reverse
parameter, which activates the session in the reverse direction.
Unplanned failures are events such as source system failure or an event on the source system that
leads to downtime for production access.
Unplanned failovers are issued from the destination system, and are indicated by setting the
is_planned parameter to false. Unplanned failovers provide production access to the original
