11. If the system image was restored on a system that is different than the one used to create
the image, you must manually delete the old MACHINEID file in /boot. Log in to the VTS
operating system, change to the root user (using the su command), and delete the file.
12. Reboot VTS by clicking Administration→System Tasks→Reboot the System.
Restoring Data Encryption
The following provides an overview of the steps you must take if you are restoring Data
Encryption as part of a disaster recovery operation. To complete these steps, one of the remote
key database backup hosts must be available. Perform these steps after restoring the VTS
database on the new server and refer to the online help for full details.
1. If necessary, upload and install the VPD file on the server. Contact your authorized
service and support representative to obtain this file.
2. Re-enable Data Encryption by removing the current license key and reinstalling the Data
Encryption license key. Contact your authorized service and support representative to
obtain a license key.
3. Delete the local key server as described in the online help.
4. Restore the key database from a remote site as described in the help. Be sure to click the
Restore from Disaster Recovery Site button, not the ADD NEW HOST button. If you
add a new backup host, VTS immediately sends a copy of the local key database to the
host, thereby overwriting the copy of the database on that host.
5. Readd the key server(s) as described in the help. This ensures that the key servers are
created with the current server’s credentials.
6. Readd the key database backup host(s) as described in the help.
Restoring replicated virtual tapes from a remote server
You can restore replicated virtual tapes as part of disaster recovery, if the source VTS server
becomes unavailable. This procedure converts a target VTS server (to which the virtual tapes
were replicated) to a source server.
After connecting a host server to the target VTS server as described in the Quick Start Guide,
complete these steps, which are performed from the command line.
Note Virtual tape names must be unique across all pools on the VTS server and all VTS
servers in the environment. If you are restoring tapes from multiple servers, it is
recommended that you restore tapes from one host at a time to avoid duplicate names.
To restore virtual tapes from a target server
1. From the command line of the VTS server, log in as the root user.
2. Use the mount command to list the devices mounted on the /DATAxx partition, where
DATAxx is the data partition designated for storing exported tapes:
mount
Here is an example of this command's output:
/dev/sda2 on / type ext3 (rw)
proc on /proc type proc (rw)
