Modifying the system list of a service group

Edit the list of systems that can host a service group. You must have the role of cluster administrator or service group administrator to modify the system list of a service group.

To modify the system list of a service group

1. In the Cluster:Groups view, in the Groups Listing table, click the linked name of the service group that you want to modify.
2. In the Group:Summary view, in the Configuration task panel, click Modify System List.
3. In the System List Configuration dialog box, specify the following details for the target systems and then click Finish. (The target systems are the systems on that can host the service group.)
   • The target system names

     Find the system you want in the list under Select and Add Systems. To quickly find a specific system, click Filter, type a few letters of the system name, and then click Apply.

     To select a system, click the system name under Select and Add Systems and then click the right-arrow button to move it under Selected Systems. You can select one or more systems.

     To reject a system, click the system name under Selected Systems and then click the left-arrrow button to move it back under Select and Add Systems.

   • The startup system

     Under Selected Systems, check the Startup option next to a system name if you want the service group to startup automatically on that system.

   • The system order of preference

     Use the up- and down-arrow buttons to the right of the Selected Systems table to set the order of systems in the list. To change the position of a system in the list, click the system name in the Selected Systems table and then click the up- or down-arrow button to move it up or down in the list.

     VCS attempts to bring the service group online on the first system in the system list, unless you have selected a different system as the startup system using the Startup option. If the service group cannot be brought online on the first system or on the designated startup system, VCS does one of the following:

     • If the first system is also the startup system, VCS attempts to bring the service group online on each remaining system in the order listed.
     • If the first system and the startup system are different, VCS attempts to bring the service group online on the first system in the list. If the first system fails, VCS attempts to bring the service group online on each remaining system in the order listed.
