Modifying the attributes for the application and its component dependency group

The VCS_Site_Info.xml file saves a site ID for both, the protected and the recovery site. It also lists the attributes for the configured application components. Each attribute must have a corresponding value on both the sites.

During a disaster, when the virtual machines fail over to the recovery site, VCS considers these attribute values and then starts the application.

Note:

You must perform this task on all the virtual machines that are a part of the protection group.

To modify the attribute values

  1. Copy the vcs_site_info.xml file and save it to the following location on a virtual machine in the protection group:

    %VCS_Home%\conf

  2. Modify the xml file to specify a SiteID for the protected and the recovery site. Also, update the required resource names and attribute values for the respective sites.

    Note:

    Ensure that the specified attribute values do not contain any of these special characters ", < and >". If the attribute values contain any of these characters, then the preonline.pl script fails to appliy the specified attributes to the respective sites.
  3. Copy and save this modified XML file on all the virtual machines.
  4. Using the VCS Java Console, perform the following tasks:

    • Select the application dependency group and set its "PreOnline Trigger" attribute to "True".

    • Ensure that the "AutoStartList" attribute includes all the virtual machines that were specified in the Failover Target System List of the application dependency group.

      Note:

      You must perform this step for each application dependency group from any virtual machine in the protection group.
