Installation Considerations

Important! The Arcserve Continuous Availability download image exceeds the amount of free disk space available on a standard compact disk (CD). To copy the download image to media, you must use a DVD or a flash drive.

Consider the following:

• Ensure your screen resolution is set to 1024 x 768 or higher. Lower resolutions may result in cropped screens.
• On Japanese environments, the Launching Application dialog may appear in English. To avoid this problem, apply .NET Framework Japanese Language Pack.

• To avoid firewall issues, install or update the Arcserve Continuous Availability Engine on Windows Server 2008 Master and Replica servers by running setup.exe locally, and then disable the Verify Arcserve Continuous Availability Engine on Hosts option during scenario creation. If you must remotely install the Arcserve Continuous Availability Engine on these machines, enable WMI traffic through the Windows Server 2008 Firewall, and then configure port 25000 on all Master and Replica machines. In addition, if you are creating Hyper-V scenarios, also enable ICMP echo messages on all Master, Replica, and Hyper-V guest machines so that Arcserve Continuous Availability can successfully ping guest operating systems.
• Note: We recommend using the Windows Firewall with Advanced Security MMC snap-in. For more information about using the Windows Firewall with Advanced Security MMC snap-in, refer to the Microsoft website.
• Before remotely installing the Arcserve Continuous Availability Engine, enable WMI traffic through the firewall:

1. From the Control Panel, open Security settings and then click Windows Firewall.
2. The Windows Firewall Settings dialog opens.

2. Click Change Settings and then click the Exceptions tab.
3. A list of programs and ports is displayed.

3. Select Windows Management Instrumentation (WMI) to enable WMI traffic through the firewall.
4. Click OK to exit firewall settings.

5. Install the Engine as usual.
6. After you install the Engine, configure port 25000 on each Master and Replica machine using the New Inbound Rule Wizard from the Windows Firewall with Advanced Security MMC snap-in.
7. Ensure TCP is selected and add port 25000 to the Specific local ports list. Allow the connection and apply to the applicable profile (for example, Private).

Note: Port 25000 is the default. You may change this port. For more information about completing the wizard, refer to the Microsoft website.

7. (For Hyper-V scenarios) Enable ICMP echo messages on all Master, Replica and Hyper-V guest machines so that Arcserve Continuous Availability can successfully ping Hyper-V guest operating systems.
8. Use the New Inbound Rule wizard to create a custom rule that enables Specific ICMP Echo Requests for any IP address and allows the connection.

Note: For more information, refer to the Microsoft website.

• Installing the Arcserve Continuous Availability Control Service with ACL-based authentication on domain controllers is not supported.
