2.7.2. Modifying a Failover Domain

To modify a failover domain, follow the steps in this section. The starting point of the procedure is at the cluster-specific page that you navigate to from Choose a cluster to administer displayed on the cluster tab.

  1. At the detailed menu for the cluster (below the clusters menu), click Failover Domains. Clicking Failover Domains causes the display of failover domains with related services and the display of menu items for failover domains: Add a Failover Domain and Configure a Failover Domain .

  2. Click Configure a Failover Domain. Clicking Configure a Failover Domain causes the display of failover domains under Configure a Failover Domain at the detailed menu for the cluster (below the clusters menu).

  3. At the detailed menu for the cluster (below the clusters menu), click the failover domain to modify. Clicking the failover domain causes the display of the Failover Domain Form page. At the Failover Domain Form page, you can modify the failover domain name, prioritize failover, restrict failover to this domain, and modify failover domain membership.

  4. Modifying failover name — To change the failover domain name, modify the text at the Failover Domain Name text box.

    Note

    The name should be descriptive enough to distinguish its purpose relative to other names used in your cluster.

  5. Failover priority — To enable or disable prioritized failover in this failover domain, click the Prioritized checkbox. With Prioritized checked, you can set the priority value, Priority, for each node selected as members of the failover domain. With Prioritizednot checked, setting priority levels is disabled for this failover domain.

  6. Restricted failover — To enable or disable restricted failover for members in this failover domain, click the checkbox next to Restrict failover to this domain's members. With Restrict failover to this domain's members checked, services assigned to this failover domain fail over only to nodes in this failover domain. With Restrict failover to this domain's membersnot checked, services assigned to this failover domain can fail over to nodes outside this failover domain.

  7. Modifying failover domain membership — Under Failover domain membership, click the Member checkbox for each node that is to be a member of the failover domain. A checked box for a node means that the node is a member of the failover domain. If Prioritized is checked, you can adjust the priority in the Priority text box for each member of the failover domain.

  8. Click Submit. Clicking Submit causes a progress page to be displayed followed by the display of the Failover Domain Form page. That page displays the added resource and includes the failover domain in the cluster menu to the left under Domain.

  9. To make additional changes to the failover domain, continue modifications at the Failover Domain Form page and click Submit when you are done.
