Virtual TapeServer 6.04.02 for NonStop Servers Supplemental Installation Guide

Enabling Instant DR and AutoCopy | 15
• It is very important that SSH communications flow though network connections from one
VTS system to another. A single gigabit connection is used to handle the SSH data
transfer and other communications between VTS systems. To prevent congestion, because
of the high volume of traffic that can flow over a connection used for Instant DR or
Autocopy, it is recommended that a completely separate gigabit subnet be used to connect
VTS systems. Network speeds of less than a gigabit are not recommended. The ProLiant
servers do not support speeds of greater than one gigabit.
After completing the procedures in this chapter, refer to the Virtual TapeServer Operations
and Administration Guide for instructions to configure the Instant DR or AutoCopy feature;
further configuration is required.
Configuring network settings on all VTS servers
To enable Instant DR and AutoCopy, 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, such
as VNC, 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. You will log in to your local VTS server but will access remote servers using FTP.
Obtain the following information before beginning this procedure:
• Root access to the VTS system; see the Virtual TapeServer Installation Guide for a list of
the default accounts provided on the server
• IP address, subnet mask, and gateway of each VTS server
The following steps use two sites as an example of enabling Instant DR or AutoCopy between
two sites, Boston and Los Angeles, connected by a wide area network (WAN):
To configure network settings
1. Log in to the physical console of the VTS system.
2. Set up the network interface on each VTS server on which you wish to enable Instant DR.
a. Log in as root.
b. Enter the root password. See the Virtual TapeServer Installation Guide for a list of
the default accounts provided on the server.
c. At the [root@site default]# prompt, enter startx. This starts the VTS operating
system UI.
d. From the operating system UI, click the Linux Start button at the bottom left-hand
side of the window.
