Modifying a service group

Edit a service group configuration. You cannot edit the service group name or type using this task. To change the name or type, you must first remove the service group and then add it back using the desired name and type. You must have the role of cluster administrator or service group administrator to edit a service group.

To edit a service group configuration

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 Service Group.
3. In the Service Group Configuration wizard, read the introductory text and then click Next.
4. In the Service Group Configuration dialog box, the service group name and type display but cannot be modified using this task. Click Next.
5. In the System List Configuration dialog box, specify the following details for the target systems and then click Next. (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.
6. In the Resource Configuration dialog box, specify the following details about the resources that belong to the service group and then click Next:
   • The member resource list

     Enter the name of any new resources that you want to add to the service group into the Resource Name text box. Resource names must:

     • Consist of only one string
     • Not contain special characters like . (period) or & (ampersand).
     • Begin with an alphabetic character.

       The remaining characters in the name can be letters, digits, hyphens, or underscores.

   • The resource startup state

     If you want the resource to start in an enabled state after the service group comes online, check Enable Resource. Click Add Resource to add the resource to the Resource List.

   • The resource attribute values or resource removal

     In the Resource List table, you can edit resource attributes or delete a resource using the buttons in the Edit and Delete columns.

     See Adding a resource to a service group.

7. If you need to link one or more resources, provide the following relationship details in the Link/Unlink Resource dialog box and then click Finish. Otherwise, click Finish now to exit the wizard.
   • The parent resource

     Use the Parent Resource drop-down menu to specify which resource must be brought online after the child resource.

   • The child resource

     Use Child Resource list box to select which resource should be brought online first, and then click Add Link.
