The library status changes to non-replicating.
Make sure its port configuration is iSCSI.
On host machine where recovery is to occur,
install iSCSI Initiator and backup application.
On the target appliance in Data Center use
Mapping Configuration page to select target
library on target appliance in Data Center and
remove slot mapping to lost source library.

Configure iSCSI Initiator Name for new
non-replicating library to match that of the
host system.
Connect to Data Center appliance and library via
iSCSI from host.
Import cartridges into backup application and
recover data to the host over WAN.
When failed D2D is replaced at remote site, use
reverse replication to recover data to it.
This recovery method is not suitable because it will
break other replication mappings.
End
Was this the only
slot mapping to this
target library?
Is it OK to
remove other
mappings?
Figure 50 Recovery process: promoting a target library over the WAN
1. On the Target Appliance in the Data Center, go to the Replication - Mapping Configuration page,
select the Target Library and remove the slot mapping between it and the lost Source Library.
2. As long as there is only one slot mapping to the Target Library, it will become a Non-Replicating
Library.
NOTE:
If there are other mappings, do not remove them if it will break other library replication. Do not
proceed, this method is not suitable.
3. Edit the port configuration of the newly promoted Non-Replicating Library to make it iSCSI.
4. Install the iSCSI initiator on the host machine at the remote site where recovery is to occur and
install the backup application.
