You can modify or delete existing rules, or add new custom rules. Rules are written in Java and

the Drools syntax.

Available hooks for customizing:

• SubnetPolicyCheck.applyFitting

• AttributeBasedSubnetPolicyCheck.applyFitting

• SpecifiedSubnetPolicyCheck.applyFitting

• AutomaticIpAddressPolicyCheck.applyFitting

• StaticIpAddressPolicyCheck.applyFitting

• DhcpIpAddressPolicyCheck.applyFitting

• PhysicalServerPolicyCheck.applyFitting

• PhysicalBootDiskPolicyCheck.applyFitting

• NPIVDataDiskPolicyCheck.applyFitting

• VirtualServerPolicyCheck.applyFitting

• EsxDiskPolicyCheck.applyFitting

• HypervDiskPolicyCheck.applyFitting

• DasDiskPolicyCheck.applyFitting

• SoftwarePolicyCheck.applyFitting

Writing a new rule file

Open a new drl file in a text editor, add the different sections of a rule file (as shown in “Rule

file” (page 198)), and add the new rule logic.

• Package—The name of the package and is always com.hp.hpio.controller.policy.

• Import—Declares the use of any other Java classes required to write the rule business logic.

• Rules:

Define multiple rules in a single rule (.drl) file.◦

◦ Each rule contains the business logic to be executed.

◦ The INIT rule is a sample structure you can duplicate and use as a starting point to define

custom rules.

Tools such as Eclipse (http://downloads.jboss.com/drools/updatesite3.3/) can be used to write

rule files by including the Drools Eclipse plug-in to the create rule project and including the required

infrastructure orchestration libraries to the project. Using Eclipse helps with syntax highlighting and

auto code completion.

For more information, see the following documentation:

• JBoss Rules User Guide at http://downloads.jboss.com/drools/docs/4.0.7.19894.GA/

html_single/index.html

• JBoss Rules at http://downloads.jboss.com/drools/docs/4.0.7.19894.GA/apidocs/index.html

Example: Custom rule

rule "CustomRule1"

when

$pVO : PolicyExecutionVO( );

$resLst : List();

/* --------------- CUSTOM LOGIC ------------------ */

// Get service entity and resource objects.

$logicalSubnet : LogicalSubnet();

$subnet : Subnet() from $resLst;

// call new user defined function with required arguments

// function has to return true in case of success or false
