Promoting a Target Share using colocation New server hardware has been purchased and installed and the admin now wants to recover data to the server. The administrator decides to move the StoreOnce appliance that was in the Data Center to the remote office (maybe only temporarily) in order to recover the server data. Figure 18 Recovery by relocating the Target Appliance . Before the failure a mapping existed between a Source Share on the remote site StoreOnce Backup System and a Target Share on the Data Center StoreOnce Backup System. After the failure the mapping still exists but the Source Share is missing. The Target Share on the Data Center StoreOnce Backup System is still in target share mode, it has not had its mappings removed. IMPORTANT: This configuration is possible in only limited situations because it will break any other backups or replications to the Data Center appliance. In a simple Active-Passive scenario, however, this may be a very good model. 1. Transport the appliance from the Data Center to the remote site and reconfigure networking, etc. 2. On the Target Appliance (now in the remote site), go to the Replication - NAS Mappings page, select the Target Share and remove the slot mapping between it and the lost Source Share. 3. The Target Share becomes a Non-Replicating Share. NOTE: If there are other share mappings, do not proceed, this method is not suitable. 4. Check that the newly non-replicating NAS share has been configured correctly to allow the required hosts to access it. 5. Recover data from the NAS share to the host over WAN. 6. 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 129. Backup System user guide 135

Promoting a Target Share using colocation
New server hardware has been purchased and installed and the admin now wants to recover data
to the server. The administrator decides to move the StoreOnce appliance that was in the Data Center
to the remote office (maybe only temporarily) in order to recover the server data.
Figure 18 Recovery by relocating the Target Appliance
.
Before the failure a mapping existed between a Source Share on the remote site StoreOnce Backup
System and a Target Share on the Data Center StoreOnce Backup System. After the failure the mapping
still exists but the Source Share is missing. The Target Share on the Data Center StoreOnce Backup
System is still in target share mode, it has not had its mappings removed.
IMPORTANT:
This configuration is possible in only limited situations because it will break any other backups or
replications to the Data Center appliance. In a simple Active-Passive scenario, however, this may be
a very good model.
1.
Transport the appliance from the Data Center to the remote site and reconfigure networking, etc.
2.
On the Target Appliance (now in the remote site), go to the
Replication - NAS Mappings
page,
select the Target Share and remove the slot mapping between it and the lost Source Share.
3.
The Target Share becomes a Non-Replicating Share.
NOTE:
If there are other share mappings, do not proceed, this method is not suitable.
4.
Check that the newly non-replicating NAS share has been configured correctly to allow the
required hosts to access it.
5.
Recover data from the NAS share to the host over WAN.
6.
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 129.
