Specify Custom HTTP/HTTPS Communication Ports

VMware vCenter Server Virtual Infrastructure (VI) SDK uses HTTP port 80 and HTTPS port 443 for Web Services communication. These particular ports may conflict with the communication ports used by Microsoft Internet Information Services (IIS). To avoid port conflicts, VMware vCenter Server and VMware ESX Server let you specify custom VI SDK Web Service ports. However, if you modify the VI SDK Web Service ports, Arcserve Backup may not be able to mount the VM data to the backup proxy system, and backups may fail.

To remedy this problem, Arcserve Backup lets you create a set of custom HTTP and HTTPS communication ports that will allow Arcserve Backup to mount the VM data to the backup proxy system.

Note: For information about how to configure VI SDK Web Services ports on VMware vCenter Server and VMware ESX Server systems, see the VMware documentation.

The remedy that follows is a global change that affects ESX Server Systems and vCenter Server systems that you back up using a particular backup proxy system. Therefore, the best practice is to identify a dedicated backup proxy system that will be used to mount data for VMware vCenter Server systems that contain a VI SDK customized port.

To specify custom HTTP/HTTPs communication ports

  1. Log in to the backup proxy system.
  2. Open Windows Registry Editor.
  3. Create the following registry key: 
    HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\CA ARCServe Backup\ClientAgent\Parameters\VIHTTPPort

    Right-click VIHTTPPort and click Modify on the pop-up menu.

    The Edit DWORD Value dialog opens.

  4. In the Value data field, specify the customized HTTP communication port number that was configured with VMware vCenter Server.

    Click OK.

    The port number is applied.

  5. Create the following resgistry key: 
    HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\CA ARCServe Backup\ClientAgent\Parameters\VIHTTPSPort

    Right-click VIHTTPSPort and click Modify on the pop-up menu.

    The Edit DWORD Value dialog opens.

  6. In the Value data field, specify the customized HTTPS communication port number that was configured with VMware vCenter Server.

    Click OK.

    The port number is applied.
