Inactive Comments Previously MODE272 CAUTION: Changing host group modes for ports where servers are already installed and configured breaks all LUN paths and will require the paths to be redefined. See "Defining the paths" on page 16. If host group mode 14 is applied to an existing LUN, Tru64 will need to be installed again. If XP Continuous Access is going to be used, the host group mode must be set before the installing Tru64. Setting the System Option Modes The HP service representative sets the System Option Mode(s) based on the operating system and software configuration of the host. Notify your HP representative if you install storage agnostic software (such as backup or cluster software) that may require specific settings. Configuring the Fibre Channel ports Configure the disk array Fibre Channel ports by using Remote Web Console (shown), or XP Command View. Select the settings for each port based on your storage area network topology. Use switch zoning if you connect different types of hosts to the array through the same switch.
