Policies control specific behaviors related to clustering and HA environments. Each policy has a name with additional information that identifies the individual policy, including the domain, such as the name of an administrative domain, or a cluster resource group (CRG) that the policy controls. Policies also contain qualifiers that identify the individual instance of that policy and extend or limit the scope of the policy's management functions. For additional information on policies see the following topics:
Below is a summary of policies that are available, a description of each policy, and which PTF(s) are required for a given policy. A PTF of 'base' indicates that the policy is available in the base release without additional PTFs.
| PowerHA Policy | Description | Supported Releases | ||
|---|---|---|---|---|
| IBM i 7.2 | IBM i 7.3 | IBM i 7.4 | ||
| Administrative Domain Policies | ||||
| QCST_AD_CREATE | Specifies which resources will be added automatically to the specified cluster administrative domain when the resource is created. | N/A | N/A | Base |
| QCST_AD_RESTORE | Specifies that when restoring a resource that is monitored by the administrative domain, that the restore of attributes shall be honored. Normally, resources with a MRE in the cluster administrative domain which are restored are immediately updated to match the attribute values in the cluster administrative domain, essentially ignoring the restore operation. | N/A | N/A | Base |
| QCST_AD_DELETE | Automates and simplifies management of the removal of monitored resources and their respective MREs from a cluster. A resource deleted on one node of the cluster administrative domain will be automatically deleted on all other active cluster nodes. Once the resource has been deleted on all cluster nodes, the MRE for the resource is also removed from the cluster administrative domain. | N/A | N/A | Base |
| QHA_AD_ANZCADPRF | Specifies policies for use in conjunction with the ANZCADPRF command to enable PowerHA to determine if profiles have been inactive for the specified number of days within a PowerHA environment by utilizing distributed information across a cluster administrative domain. | SI72439 | SI72439 | SI72362 |
| Cluster Resource Group Policies | ||||
| QCST_CRG_CANCEL_FAILOVER | Prevents automatic CRG failovers from taking place for the specified CRG and events. | N/A | N/A | Base |
| Communication Policies | ||||
| QHA_COMM_STRICT_CERT_CHECK | Controls the configuration of security settings governing communication between PowerHA and a storage device using IBM Copy Services Manager (CSM). | SF99776 Level 11 | SF99876 Level 8 | Base |
