Installation guide

When adding a resource to a service, whether it is an existing global resource or a
resource available only to this service, you can specify whether the resource is an
In d ep en d en t Su b t ree or a No n - Crit ical Reso u rce.
If you specify that a resource is an independent subtree, then if that resource fails only
that resource is restarted (rather than the entire service) before the system attempting
normal recovery. You can specify the maximum number of restarts to attempt for that
resource on a node before implementing the recovery policy for the service. You can also
specify the length of time in seconds after which the system will implement the recovery
policy for the service.
If you specify that the resource is a non-critical resource, then if that resource fails only
that resource is restarted, and if the resource continues to fail then only that resource is
disabled, rather than the entire service. You can specify the maximum number of restarts to
attempt for that resource on a node before disabling that resource. You can also specify
the length of time in seconds after which the system will disable that resource.
9. If you want to add child resources to the resource you are defining, click Ad d C hi l d
R eso urce. Clicking Ad d C hi l d R eso urce causes the display of the Ad d Reso u rce T o
Service drop-down box, from which you can add an existing global resource or add a new
resource that is available only to this service. You can continue adding children resources to
the resource to suit your requirements.
Note
If you are adding a Samba-service resource, add it directly to the service, not as a
child of another resource.
Note
When configuring a dependency tree for a cluster service that includes a floating IP
address resource, you must configure the IP resource as the first entry and not as the
child of another resource.
10. When you have completed adding resources to the service, and have completed adding
children resources to resources, click Submi t. Clicking Submi t returns to the Service
G ro u p s page displaying the added service (and other services).
