Figure 10 Recovery by promoting a Target Library . Before the failure a mapping existed between a Source Library on the remote site StoreOnce Backup System and a Target Library on the Data Center StoreOnce Backup System. After the failure the mapping still exists but the Source Library is missing. The Target Library on the Data Center StoreOnce Backup System is still in Target Library mode, it has not had its mappings removed. IMPORTANT: This recovery method is not suitable if the Target Library also has slot mappings from Source Libraries on other remote sites. 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. 5. Configure the iSCSI Initiator Name for the newly promoted Non-Replicating Library to be that of the host system. 6. Connect to the Data Center appliance and library via iSCSI from the host at the remote site. 7. Import the cartridges into the backup application and recover the data over the WAN. 8. At this point there is no HP StoreOnce Source Appliance at the remote site. If one is installed at a later date, you can reverse recover the data and configure replication, as described in "Reverse replication using the wizard" on page 119. 124 Restore processes with replication

Figure 10 Recovery by promoting a Target Library
.
Before the failure a mapping existed between a Source Library on the remote site StoreOnce Backup
System and a Target Library on the Data Center StoreOnce Backup System. After the failure the
mapping still exists but the Source Library is missing. The Target Library on the Data Center StoreOnce
Backup System is still in Target Library mode, it has not had its mappings removed.
IMPORTANT:
This recovery method is not suitable if the Target Library also has slot mappings from Source Libraries
on other remote sites.
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.
5.
Configure the iSCSI Initiator Name for the newly promoted Non-Replicating Library to be that of
the host system.
6.
Connect to the Data Center appliance and library via iSCSI from the host at the remote site.
7.
Import the cartridges into the backup application and recover the data over the WAN.
8.
At this point there is no HP StoreOnce Source Appliance at the remote site. If one is installed at
a later date, you can reverse recover the data and configure replication, as described in
“
Reverse
replication using the wizard
”
on page 119.
