Configuring Resource Dependencies
Groups function properly only if resource dependencies are configured correctly. The Cluster Service 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
Table 5-2. Cluster Resources and Required Dependencies
Resource | Required Dependencies |
|
|
File share | Network name (only if configured as a distributed file system [DFS] root) |
IP address | None |
Network name | IP address that corresponds to the network name |
Physical disk | None |

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 the Cluster Service 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 the Cluster Service 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 the 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.
