8. This takes you to the Edit Slot Mapping step. Enter a Slot Mapping Name. The slot number and
barcodes of all source cartridges are displayed. A new barcode is generated for them on the
target library. By default, all slots on the Source are selected for mapping and mapped to available
slots on the Target library. If you want to deselect cartridges from this slot mapping configuration,
select Unmapped from the Target Slot Name drop-down menu.
9. Click Apply to create the slot mapping configuration. Replication of cartridges will start
immediately.
NOTE:
If you were able to colocate the Target Appliance on the same LAN as the Source Appliance
to improve replication performance, remember to relocate the Target Appliance to the target
site as soon as the cartridges are synchronized.
Recovering a Source Appliance
There are three basic models for recovering data using D2D systems and, within these, there are
sub-models depending on the state from which the user is recovering:
1. Reverse Replication
• When the source device and host servers are lost, but the replication mapping is still present
on the target
• When the source device is lost and the mapping between the source and the target is broken
or removed
2. Target Promotion
• The target is accessed over the WAN using iSCSI
