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.

created with the current server’s credentials.

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. In this example, /dev/sdb1 is mounted on
DATA01.
/dev/sda2 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/sda1 on /boot type ext3 (rw)
/dev/sda4 on /VAULT00 type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
192.168.60.40:/TEST/TEST on /TEST type nfs (rw,soft,
addr=192.168.60.40)
/dev/sdb1 on /DATA01 type ext3 (rw)
3. Unmount the data partition. For this example, unmount DATA01:
umount /DATA01
