Configuring MC/ServiceGuard Package Dependencies with the PSM

Configuring Package Dependencies using SAM

The procedure assumes you have taken the necessary steps to create the package to which you will be adding resource dependencies. Complete instructions for configuring MC/ServiceGuard clusters and packages are provided in Managing MC/ServiceGuard.

To create a package resource dependency:

1.From the command line, start the graphical version of SAM by typing: sam

2.Double-click the Clusters icon.

3.Double-click the High Availability Clusters icon.

4.Double-click on the Package Configuration icon.

The High Availability Clusters screen is displayed showing all requests configured on that system.

5.From the Actions menu, select either Create/Add a Package or Modify Package Configuration.

Depending on which option you selected, the Create/Add Package screen is displayed or the Modify Package screen is displayed.

6.If you have not yet done so, specify a Package Name and Node and Specify a Package SUBNET Address. Then click on “Specify Package Resource Dependencies…” to add PSM resources as package dependencies. The Package Resource Dependencies screen is displayed.

7.To make a package dependent on an EMS HA Monitors resource, click Add Resource. The Add Resources screen is displayed listing all the installed resources discovered by MC/ServiceGuard. The resource classes used for PSM monitoring are adapters, connectivity, storage, and system.

8.Double-click on the appropriate PSM resource class, then on the status class, then on the remaining resource subclasses until the PSM monitor instances are displayed in the Resource Names list. Select the desired PSM resource and click OK. A Resource Parameters screen is displayed

9.Enter an appropriate Resource Polling Interval value. This value determines how often EMS checks the PSM for changes in status. The value you select for polling should be related to how critical the resource is to system operation. You may want to use a short polling interval for critical resources, and a longer interval for non-critical resources. Be aware that polling can impact system performance, so avoid using a short polling interval for all resources.

10.Select UP from the list of Available Resource Values, then click < — Add — .

11.Click OK to add the package dependency.

Package failover will now occur if the status of the resource changes from UP.
