tabs.

Properties of a cluster object should not be updated on multiple nodes simultaneously. See the MSCS online documentation

for more information.

Resource Dependencies

Groups function properly only if resource dependencies are configured correctly. MSCS uses the dependencies list when

bringing resources online and offline. For example, if a group in which a physical disk and a file share are located is brought

online, the physical disk containing the file share must be brought online before the file share.

Table 5-2

shows resources and their dependencies. The resources in the right column must be configured before you create

the resource.

Setting Advanced Resource Properties

You can configure the advanced resource properties using the Advanced tab in the resource Properties dialog box. Use the

Advanced tab to have MSCS perform the following tasks:

Restart a resource or allow the resource to fail.

To restart the resource, select Affect the group (if applicable).

To fail over the resource group to another cluster node when the resource fails, select Affect the group and

then enter the appropriate values in Threshold and Period. If you do not select Affect the group, the resource

group will not fail over to the healthy cluster node.

The Threshold value determines the number of attempts by MSCS to restart the resource before the resource fails

over to a healthy cluster node.

The Period value assigns a time requirement for the Threshold value to restart the resource.

Adjust the time parameters for Looks Alive (general check of the resource) or Is Alive (detailed check of the

resource) to determine if the resource is in the online state.

Select the default number for the resource type.

To apply default number, select Use resource type value.

Specify the time parameter for a resource in a pending state (Online Pending or Offline Pending) to resolve its

status before moving the resource to Offline or Failed status.
