Install ContinuousDataReplicator - Clustered Environment - Virtual Server

Click on a link below to go to a specific section of the software installation:

Install Requirements
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 step-by-step instructions, see Install ContinuousDataReplicator - Clustered Environment - Physical Node.

ContinuousDataReplicator can be installed from the active node to the virtual server using the following procedure. The software can also be automatically installed on all available passive nodes when the software is installed onto the virtual server, or you can choose to install any passive node(s) separately.

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.

The following procedure describes the steps involved in installing 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.
  • If a MediaAgent or Client on a Microsoft Windows MSCS virtual server needs to communicate with other CommCell components across a firewall, you must:
    • Install File System iDataAgent or MediaAgent on all the physical nodes of the cluster. During the installation, use the firewall related prompts to establish the firewall settings required by the software to communicate across the firewall.
    • Then install the software components on the virtual nodes. (It is not necessary to configure the firewall settings again in the virtual nodes.)
    If the cluster communicates with the CommServe across a one-way firewall, you must add both the physical and virtual nodes' host names (or the IP addresses) in the CommServe computer before installing the software.

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.

  • If firewall configuration is not required, click No, do not configure firewall services and then click Next to continue. Proceed to the next section.

NOTES

  • Operating systems, such as Windows 2008 and Windows Vista, may have more than one profile present. When you select No to configure firewall services, verify that firewall settings are not enabled in the profile(s).
  • If the system detects firewall settings are present in the profile(s), you must select from the following:
    • Disable firewall for ALL profiles: Employ caution when choosing this option; firewall settings will be disabled in all profiles. This requires a system reboot; installation automatically resumes after reboot.
    • No, Firewall is not enabled: Select this option if your firewall settings allow communication with the CommServe computer.
      Click Back to configure firewall services.
12. 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.
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.

Click Next to continue.
14. If desired, modify the Keep Alive interval.

Click Next to continue.
15. Optionally, select Advanced Firewall Configuration and specify a local host name interface to use for outgoing tunnel connections through the firewall. Otherwise, the interface and port is automatically selected for you by the OS.

Click Next to continue.
16. If desired, modify the Tunnel Initialization interval.

Click Next to continue.

If any of the above prompts for firewall configuration is not displayed, you must configure communication across firewall(s) using the Firewall Configuration Wizard before running any operations on this computer. (See Configure or Modify Firewall Settings on Windows Computers for step-by-step instructions on using the Firewall Configuration Wizard.)

Configuration of Other Installation Options
17. Enter the following:
  • The local (NetBIOS) name of the client computer.
  • The TCP/IP IP host name of the NIC that the client computer must use to communicate with the CommServe Server.

NOTES

  • Do not use spaces when specifying a new name for the Client.
  • The default network interface name of the client computer is displayed if the computer has only one network interface. If the computer has multiple network interfaces, enter the interface name that is preferred for communication with the CommServe Server.
  • If a component has already been installed, this screen will not be displayed; instead, the install program will use the same name as previously specified.

Click Next to continue.
18. Enter the username and password information for an external domain user account or a CommCell user account. This authorizes the installation of an agent on the CommCell.

NOTES

  • This window is only displayed when the Require Authentication for Agent Installation option is selected in the CommCell Properties. Users must belong to a User Group with Administrative Management capabilities to enable this feature. For more information, see Authentication for Agent Installs.

Click Next to continue.
19. Specify the following and click Next to continue:
  • Type the location of the client's job results directory, or click Browse.

NOTES

  • The Agent uses the job results directory to store the client's backup and restore job results.

  • UNC paths are supported for job results directory by the Exchange Database iDataAgent 2007 and above when configured in Cluster Continuous Replicator environment. Also note that Windows iDataAgent is also supported when configured in this environment.

20. Select Download Pack(s) and Install to download and install the latest service packs and post packs from the software provider.

When you have completed your selections, click Next to continue.
26. Type the User Name and Password for the Domain Administrator account, so that the installer can perform the remote install/upgrade of the cluster nodes you selected in the previous step.

Click Next to continue.
27. The progress of the remote install for the cluster nodes is displayed; the install can be interrupted if necessary.

Click Stop to prevent installation to any nodes after the current ones complete.

Click Advanced Settings to specify any of the following:

  • Maximum number of nodes on which Setup can run simultaneously.
  • Time allocated for Setup to begin executing on each node, after which the install attempt will fail.
  • Time allocated for Setup to complete on each node, after which the install attempt will fail.

NOTES

  • If, during the remote install of a cluster node, setup fails to complete or is interrupted, you must perform a local install on that node. When you do, the install begins from where it left off, or from the beginning if necessary. For procedures, see Manually Installing the Software on a Passive Node.
28. Read the summary for remote installation to verify that all selected nodes were installed successfully.

NOTES

  • If any node installation fails, you must manually install the software on that node once the current installation is complete. (See Manually Installing the Software on a Passive Node for step-by-step instructions.)
  • The message displayed on your screen will reflect the status of the selected nodes, and may look different from the example.

Click Next to continue.

Setup Complete
29. Setup displays the successfully installed components.

NOTES

  • The Setup Complete message displayed on your screen will reflect the components you installed, and may look different from the example shown.
  • If you install an Agent with the CommCell Console open, you need to refresh the CommCell Console (F5) to see the new Agents.
  • If Reboot Now button is displayed make sure to reboot the computer before performing any other operations from the computer.

Click Finish to close the install program.

The installation is now complete.
30. Note that the following will automatically be filtered:
  • The physical cluster nodes will automatically filter all shared disk resources.
  • Virtual servers will automatically filter all physical disk resources.

NOTES

Post-Install Considerations

General

  • Install post-release updates or Service Packs that may have been released after the release of the software. If you are installing a Service Pack, verify and ensure that it is the same version as the one installed in the CommServe Server. Alternatively, you can enable Automatic Updates for quick and easy installation of updates in the CommCell component.
  • The following items include some of the most common features that can be also be configured:
    • Schedule your data protection operations - see Scheduling for more information.
    • Configure Alerts - See Alerts and Monitoring for more information.
    • Schedule Reports - See Reports for more information.

The software provides many more features that you will find useful. See the Index for a complete list of supported features.

Agent Specific

  • The following configuration tasks are required before you can begin using the software for data protection operations:
    1. Ensure that ContinuousDataReplicator is installed on both the source and destination computers.
    2. Create a Replication Set on the source computer.
    3. Add a Replication Pair to the Replication Set you created on the source computer.

Cluster

  • If the passive node was not available while installing the software, you must manually install the software on the passive node now. (See Manually Installing the Software on a Passive Node for step-by-step instructions.)
  • By default, a failure of MediaAgent or Agent software on the active node in a Windows, Veritas, or HP Scalable NAS/PolyServe Cluster will not cause a failover to be initiated. For information on how to change this default behavior, see Clustering Support - Failovers.

  • After the installation of software is complete for all the physical nodes, and CDR software has been installed on the cluster virtual server, stop and restart CDR Services on all of the physical nodes before you begin using CDR on the virtual server for data replication. For more information about how to do this, see Services - How To.
