The Remove Cluster Resource Group Device Entry (QcstRmvClusterResourceGroupDev) API removes one or more configuration objects from a device cluster resource group. All configuration object entries can be removed but at least one configuration object entry must exist before the Start Cluster Resource Group (QcstStartClusterResourceGroup) API can be called.
Ownership of the hardware associated with the configuration object being removed is not affected. The hardware is still owned by whatever node owned it before this API was called.
If an exit program is specified for the cluster resource group, the cluster resource group exit program is called with an action code of Remove Device Entry (18) on all active nodes in the recovery domain. The cluster resource group status is set to Remove Device Entry Pending (600). If the exit program completes successfully, the cluster resource group status is reset to its value at the time the API was called. If the exit program fails and the cluster resource group cannot be restored to its original condition, the cluster resource group status is set to Indoubt (30).
Removing a device from a cluster resource group does not vary the device off.
This API requires:
Restriction: This API cannot be called from a cluster
resource group exit program.
The program that calls this API must be running under a user profile with *IOSYSCFG special authority.
A unique string or handle that identifies this API call. It is used to associate this call to any responses placed on the user queue specified in the results information parameter.
The name of the cluster to which the cluster resource group belongs.
The name of the cluster resource group which is to be changed.
Detailed information about the configuration objects to be added to the cluster resource group. For more information, see Device Resiliency (RGDR0100 Format).
The content and format of the configuration object information. The possible format names are:
| RGDR0100 | This format describes the resilient device. |
This parameter identifies a qualified user queue field and is followed by a reserved field.
Qualified user queue: Completion information is returned to this user queue, which exists on the node from which the API was called, after the function has completed. See the Usage Notes section of this API for a description of the data that is placed on this queue. This is a 20-character field. The first 10 characters contain the user queue name, and the second 10 characters contain the user queue library name. No special values are supported. QTEMP, *LIBL, *CURLIB are not valid library names. The attributes of this user queue must be keyed.
Reserved: The last 10 characters of the 30-character results information are reserved. Each character in this field must be set to hexadecimal zero.
The structure in which to return error information. For the format of the structure, see Error code parameter.
| Offset | Type | Field | |
|---|---|---|---|
| Dec | Hex | ||
| 0 | 0 | BINARY(4) | Offset to configuration object array |
| 4 | 4 | BINARY(4) | Number of entries in configuration object array |
| 8 | 8 | BINARY(4) | Length of configuration object array entry |
| 12 | C | BINARY(4) | Offset to additional fields |

| * | * | Array (*) of CHAR(16) | Configuration object array |
| These fields repeat, in the order listed, for each device. | CHAR(10) | Configuration object name | |
| CHAR(2) | Reserved | ||
| BINARY(4) | Configuration object type | ||
Configuration object name. The name of the configuration object which is to be removed from the cluster resource group.
Configuration object type. This specifies the type of configuration object specified with configuration object name. Possible values are:
| 1 | Device description |
| 2 | Controller description |
| 3 | Line description |
| 5 | Network server description |
Length of additional fields. The length in bytes of additional fields. This must be set to hexadecimal zero. It will be used in a future release if more fields are needed in the RGDR0100 format.
Length of configuration object array entry. This specifies the length of an entry in the configuration object array.
Number of entries in configuration object array. The number of entries in the configuration object array. This must be greater than zero and less than or equal to 256.
Offset to additional fields. The byte offset from the beginning of this parameter to additional fields. This must be set to hexadecimal zero. It will be used in a future release if more fields are needed in the RGDR0100 format.
Offset to configuration object array. The byte offset from the beginning of this parameter to the configuration object array field.
Reserved. Must contain hexadecimal zeroes.
Asynchronous results are returned to a user queue specified by the Results Information parameter of the API. See Cluster APIs Use of User Queues and Using Results Information for details on how to create the results information user queue, the format of the entries, and how to use the data placed on the queue. The data is sent to the user queue in the form of a message identifier and the substitution data for the message (if any exists). The following identifies the data sent to the user queue (excluding the message text).
