Before you can install
ContinuousDataReplicator on the virtual server in a clustered
environment, you must first install QSnap and the Driver for
ContinuousDataReplicator on all physical nodes of the cluster.
For an overview of deploying the software components in a clustered environment,
see Clustering Support.
ContinuousDataReplicator is installed on
at least two machines; the server from which you will replicate data
(source computer) and the computer to which you will replicate the
data (destination computer.) You may choose to perform additional
installations, based on the
Replication Scenario used in your particular environment.Verify that the computers in which you
are installing the software satisfy the minimum requirements specified in
System Requirements -
ContinuousDataReplicator and in
System Requirements -
QSnap with Other Agents.
The following procedure describes the steps involved in installing
QSnap and the Driver for ContinuousDataReplicator. If you choose to install multiple components simultaneously, refer to the
appropriate procedures for installation requirements and steps specific to
the component. Note that when you install multiple components, the
sequence of the install steps may vary; if you have already install
CommCell components, some of the screens shown in this procedure will not
appear. Review the following Install Requirements before installing the software:
General
- If any of the computers in which you are installing this
software have multiple Network Interface Cards (NIC) you must
configure them so that the source and destination computers can
communicate for replication activities. For more information, see
Data Interface Pairs.
- Agents should only be installed
after the CommServe and at least one MediaAgent have already been installed in
the CommCell. Also, keep in mind that the CommServe and MediaAgent must be installed and running (but not
necessarily on the same computer), before you can install the
Agent.
- This version of the software is intended to be installed in a CommCell
where the CommServe and MediaAgent(s) version is 8.0.0.
- Close all applications and disable any programs that run automatically,
including anti-virus, screen savers and operating system utilities. Some of
the programs, including many anti-virus programs, may be running as a service.
Stop and disable such services before you begin. You can re-enable them after
the installation.
- Ensure there is an available license on the CommServe for the Agent.
- Verify that the
software
installation disc is appropriate to the operating system of the computer
on which the software is being installed.
Make sure that you have the latest
software
installation disc before
you start to install the software. If you are not sure, contact your
software provider.
Firewall
- If the CommServe® Server, MediaAgent and/or Clients communicate across two-way firewall(s):
- Ensure port 8400 is allowed connections through the firewall.
- In addition a range of bi-directional ports (consecutive or
discrete) must also be allowed connections through the
firewall.
For information on configuring the range of ports, see
Port
Requirements for Two-way Firewall.
- If the CommServe Server, MediaAgent and/or Clients communicate across one-way firewall(s):
- Identify a range of outbound ports (consecutive or discrete) for use
by the software.
For information on configuring the range of ports, see
Port
Requirements for One-way Firewall.
-
If the MediaAgent/Client communicates with the CommServe Server across a one-way
firewall, you must add the MediaAgent/Client host name (or the IP address) in
the CommServe computer before installing the necessary software on the
MediaAgent/Client computer.
Cluster
- Check the following on the cluster computer in which you wish to install the
software:
- Cluster software is installed and running.
- Active and passive nodes are available.
- Disk array devices configured with access to the shared array.
- Public Network Interface Card is bound first, before the private Network
Interface Card. (Does not apply to NetWare Cluster.)
Agent Specific
- In addition to a license for ContinuousDataReplicator, you must have
an available license on the CommServe for any snapshot engines and copy
managers you plan to use.
-
A reboot will be required after install/upgrade to initialize the QSnap
driver, before you can use this Agent.

Click the Specify list of machine across the firewall option and then
specify the list of hosts separated from this computer by a firewall. Make sure
you correctly describe whether the firewall allows two-way communication (but on
a limited range of ports), or one-way communication (with either only remote
host being able to make connections to this computer, or vice versa).
For all one-way firewalls allowing incoming connections and those one-way
firewalls allowing outgoing connections without additional port filtering, skip
this step.
Click Next to continue.
NOTES
- Consider the following:
- On the CommServe Server, this list should include all the
MediaAgents and Clients that are on the other side of the
firewall.
- On the MediaAgents/Clients this should include the CommServe
computer, and any other Clients/MediaAgents on the
other side of the firewall with which communications will be
established.
- For each machine on the other side of the firewall that you want to
configure, choose the type of firewall configuration based on the firewall setup in
your environment. Choose from the following options:
- Click on 2-way firewall if you can open certain ports as
bi-directional ports.
- Click 1-way firewall; host is reachable from this machine
on the machine that is on the secure side of the firewall.
- Click 1-way firewall; host is NOT reachable from this machine
on the machine that is on the public / DMZ side of the firewall.
- If you wish to communicate with computers in a clustered
environment, ensure that you add the Host Name/IP Address of all
physical nodes in the cluster (even if no CommCell components are
installed) and all the virtual nodes in which CommCell components are
installed.
- Type the host name or the IP address and the GxCVD port number of the
host name, and
click Add to place it in the Host Name/IP Address List.
|
![](../screens/common/firewall_host_name.gif) |
13. |
Click the Specify list of restricted open ports option and then
specify the port range. Add the starting and ending port range and then click
Add to place it in the Open Port List. Repeat as needed.
If firewall separating this computer from others allows incoming connections,
but these connections can be made only on a limited set of ports, then configure
the appropriate port range here. For all other scenarios, skip this step.
Note that if you do not specify hostname(s) as well as port number(s), then
the firewall services will not be configured.
NOTES
- Typically in a two-way firewall, the open ports must be indicated for
all computers. In a one-way firewall, the ports must be specified on
computers in the open side, if they are open in a restricted way. Note that
the port ranges are not required for computers that are fully closed in the
one-way firewall. For example, laptops which are configured as clients in
the Workstation Backup Agent.
- In a clustered environment, make sure the firewall ports specified here
are open for communication on all the physical nodes as well as the virtual
nodes.
