PowerHA Policies

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 Managing PowerHA Policies.

Saving and Restoring PowerHA Policies

PowerHA policies may not be handled as anticipated with system save, restore and migration operations. We recommend using the Save PowerHA Policy (SAVHAPCY) command to save PowerHA policies to an IFS file and the Restore PowerHA Policy (RSTHAPCY) command to add PowerHA policies from an IFS file.

It is recommended to verify PowerHA policies are defined as expected after the recovery or migration of a system to ensure policies are configured as expected. Since policies are cluster-wide, depending on the process followed, a system recovery or migration can result in unexpected changes in policies.

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
PowerHA Policy	Description	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.	SF99776 Level 14 or SI72439	SF99876 Level 11 or SI72439	SF99666 Level 3 or 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 or SI69233	SF99876 Level 8 or SI69233	Base
