The CRG_CONFIGURATION_OBJECTS table function returns details about configuration objects managed by a cluster resource group.

Authorization

The authorization ID of the statement must include the following privileges:

Authorization as required by PowerHA product functionality.
Input/output system configuration (*IOSYSCFG) special authority.
Allows access to the object attributes and use of the object(*USE) to the CRG object.

Parameters

QHASM.CRG_CONFIGURATION_OBJECTS ( CLUSTER_RESOURCE_GROUP => cluster-resource-group-name )

The schema is QHASM.

cluster-resource-group-name

Specifies the name of the cluster resource group.

Result Table

The result of the function is a table containing a row for each configuration object in the CRG with the format shown in the following table. This is only valid for device CRGs. An empty table is returned for other CRG types.

Column Name	Data Type	Description

Column Name	Data Type	Description
CLUSTER_RESOURCE_GROUP	VARCHAR(10)	The name of the cluster resource group
CONSISTENT_INFORMATION	VARCHAR(3)	Indicates whether or not the displayed information is consistent with other nodes in the cluster. YES The information is consistent for all active nodes in the cluster. NO The information retrieved from the node running the command may not be consistent with all the active nodes in the cluster. In order to obtain consistent information run the command on an active node, or start this node and run the command again.
CONFIGURATION_OBJECT	VARCHAR(10)	The configuration object name for a device entry. An example of this would be the auxiliary storage pool device description name.
OBJECT_TYPE	VARCHAR(10)	The type of configuration object specified with configuration object name. DEVD A device description. The DEVICE_TYPE column indicates the type of device description. IPA IP Address.
DEVICE_TYPE	VARCHAR(10) Nullable	The type of device description. ASP An auxiliary storage pool device. Contains the null value if there is no device type or if the OBJECT_TYPE is not of type *DEVD.
DEVICE_SUBTYPE	VARCHAR(10) Nullable	UNKNOWN The subtype cannot be determined because hardware configuration is not complete. UDFS UDFS independent auxiliary storage pool. SECONDARY Secondary independent auxiliary storage pool. PRIMARY Primary independent auxiliary storage pool. Contains the null value if the device type does not have a subtype.
VARY_ONLINE	VARCHAR(10)	Indicates what configuration action to take when the cluster resource group is switched over or failed over to a backup node. Switchover and failover completion may be delayed if the varyon of devices takes a long time. OFFLINE Remains varied off and leaves the server takeover IP address inactive CURRENT For a configuration object of type DEVD, preserves the VARY status of the configuration object and the status of the server takeover IP address. If the configuration object was online prior to the switchover or failover, the configuration object will vary on after the switchover of failover completes and will start the server takeover IP address. If the configuration object was offline prior to the switchover or failover, the configuration object will not vary on after the switchover or failover completes and will not start the server takeover IP address. ONLINE Is varied on and starts the server takeover IP address. For a configuration object of type IPA, the IP address is also started when the cluster resource group is started, and ended when the cluster resource group is ended. PRIMARY For a configuration object of type *DEVD, same as the associated primary auxiliary storage pool
SERVER_TAKEOVER_IP_ADDRESS	VARCHAR(45)Nullable	This is a takeover IP address for servers associated with the relational database name in the device description for an auxiliary storage pool, or the IP address for a configuration object with type *IPA. The address may be an IPv4 address or IPv6 address. Contains the null value if no server takeover IP address is defined.

Examples

Example 1 - Get the list of configuration objects in a device CRG

The following example gets the list of configuration objects in the CRG named MYCRG.

SELECT CONFIGURATION_OBJECT, VARY_ONLINE, SERVER_TAKEOVER_IP_ADDRESS
  FROM TABLE(QHASM.CRG_CONFIGURATION_OBJECTS(CLUSTER_RESOURCE_GROUP => 'MYCRG'));

Example 1 - Sample Output

CONFIGURATION_OBJECT	VARY_ONLINE	SERVER_TAKEOVER_IP_ADDRESS

CONFIGURATION_OBJECT	VARY_ONLINE	SERVER_TAKEOVER_IP_ADDRESS
PRODIASP	*ONLINE	192.0.2.10
ARCHIVEASP	*PRIMARY	-

Example 2 - Get the list of IASP devices not in a cluster resource group

This example finds the list of IASP devices on the local system that are not in a cluster resource group.

SELECT ASPINFO.DEVICE_DESCRIPTION_NAME FROM
  QSYS2.ASP_INFO ASPINFO
  WHERE NOT EXISTS (
    SELECT CONFIGURATION_OBJECT
      FROM (SELECT CLUSTER_RESOURCE_GROUP FROM QHASM.CRG_LIST WHERE CRG_TYPE = '*DEV') AS CRGLIST,
           TABLE(QHASM.CRG_CONFIGURATION_OBJECTS(CLUSTER_RESOURCE_GROUP => CRGLIST.CLUSTER_RESOURCE_GROUP)) CFGOBJ
      WHERE ASPINFO.DEVICE_DESCRIPTION_NAME = CFGOBJ.CONFIGURATION_OBJECT);

Example 2 - Sample Output

DEVICE_DESCRIPTION_NAME

DEVICE_DESCRIPTION_NAME
MYIASP
