Virtual TapeServer 8.3 Configuration Guide

c. Enable jobs on Server B.
d. If Data Encryption is used in the environment and Server A was the key generator, you
do not need to perform additional steps to continue to use Data Encryption after
swapping roles. However, if Server A is not available, you can restore a backup of
Server A’s key database from a remote host. Then, you can configure Server B to be the
key generator. See the Managing Data Encryption help topics in the online help for
details.
e. Back up data from host servers to Server B as needed.
At this point, Server B has become the primary server.
To restore roles
1. Cease production on Server B:
l Stop all backup operations to Server B.
l Disable all jobs on Server B, including the remote export jobs that export data to
Server A. See the “Modifying a job” help topic in the online help.
l Remove virtual tapes from all VTLs on Server B. See the “Removing a virtual tape from
a VTL” help topic for details.
2. Load virtual tapes that were exported from Server B in VTLs on Server A. These virtual tapes
are needed by the host servers, to back up data on Server A. See the “Adding a virtual tape to
a VTL” help topic for details.
3. Enable jobs on Server A.
4. Back up data from host servers to Server A as needed.
Configuring network settings
You must configure network settings for all VTS locations. To configure the local system, you must
attach a monitor, keyboard, and mouse to the VTS server. To configure remote systems, you must
use a remote-access application to access those systems, or perform the steps at each site. The IP
address, which will differ for each VTS server, must be configured at the local and remote sites.
Consult your network administrator to determine the gateway and subnet mask to use for each
system.
In addition, you should be familiar with networking concepts to complete the steps in this section.
Obtain the following information before beginning this procedure:
l Root access to the VTS system; see "Managing operating system accounts" on page 131 of the
default accounts provided on the server
l IP address, subnet mask, and gateway of each VTS server
