Decide on your link rules

Before you can run the default reconciliation task that links assets and CIs, you need to decide what link rules to use. A reconciliation task requires at least one link rule to run. A default link rule is supplied with the product, and you can create additional link rules of your own.

You can include in the default reconciliation task, CCILinkAssetsAndCIs, one or more of the following link rules:

The default link rule for linking assets and CIs that have matching serial numbers.
A new link rule that you create yourself using any common attribute that exists on both your assets and CIs.

The default reconciliation task requires at least one link rule and acts on all assets and CIs that are not already linked.

Link rule that matches serial numbers

You can use the sample link rule, CCIAssetCISerialNum, that is included with the reconciliation task and links authorized assets and CIs with identical serial numbers:

asset.serialnum=cispec.COMPUTERSYSTEM_SERIALNUMBER

The default link rule includes eleven OR clauses, one clause for each of the following classes:

CI.COMPUTERSYSTEM
CI.AIXCOMPUTERSYSTEM
CI.HPUXCOMPUTERSYSTEM
CI.LINUXCOMPUTERSYSTEM
CI.SUNCOMPUTERSYSTEM
CI.SYSTEMPCOMPUTERSYSTEM
CI.UNITARYCOMPUTERSYSTEM
CI.VIRTUALCOMPUTERSYSTEM
CI.VMWARECOMPUTERSYSTEM
CI.WINDOWSCOMPUTERSYSTEM
CI.ZSERIESCOMPUTERSYSTEM

This default link rule will try to match the asset number from Data Set 2 (attribute serialnum) with the CI number from Data Set 1 (attribute COMPUTERSYSTEM_SERIALNUMBER). A clause has been added to the link rule for every computer class supplied with the product. So if you have created additional computer classes of your own, you will need to add a clause for each of those.

Link rules that match other common attributes

You might want to create your own link rules that match authorized assets and CIs based on other common attributes of your own choosing.

For each new customized link rule that you create, in the Link rules application select CI as Data Set 1 and select ASSET as Data Set 2. Doing this indicates that you want to use your link rule for asset-CI linking in particular. (Note that the data sets must be specified exactly this way; you cannot flip the CI and ASSET values.)
