Recovering the server configuration
If the VTL server configuration is lost or corrupt, you can recover it from a backup
file using the procedure below.
Caution – This is a disaster recovery procedure only. Never execute it during day‐
to‐day operation of the server. Restoring a configuration overwrites existing virtual
device and client configurations and does not restore VTL partition information.
Restoring the configuration
1. In the object tree of the VTL console, select the branch for the VTL server that has
lost its configuration information.
2. From the VTL main menu, select Tools.
3. From the submenu, select Restore Configuration.
4. Click OK to confirm.
5. When prompted, locate the backup configuration file.
The VTL server restarts. Resources added after the configuration was saved will
show up in the Virtual Vault after the configuration is restored. Deleted
resources will be displayed in the virtual tape library with a red dot, indicating
incomplete status.
Stop here.
Protecting VTL metadata
The VTL database holds the metadata that maps data stored on virtual tape to
locations on the physical, random‐access disk media. Without this critical
information, virtual tape data cannot be recovered, so protecting it is essential.
Sun StorageTek VTL appliances protect this metadata by storing it on a RAID
system, a set of storage disks configured to survive the loss of any single member of
the set without loss of data.
