<p>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 <a href="clrgstcrg.htm">Start Cluster Resource Group (QcstStartClusterResourceGroup)</a> API can be called.</p>
<p>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.</p>
<p>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).</p>
<p>Removing a device from a
cluster resource group does not vary the device off.</p>
<p>This API requires:</p>
<ol>
<li>Cluster Resource Services must be active on the node processing the
request.</li>
<li>If an exit program is specified, the exit program must exist on all nodes
in the recovery domain.</li>
<li>At least one node in the recovery domain must be active.</li>
<li>If the cluster resource
group is active, all members of an auxiliary storage pool group must be removed
at the same time. </li>
<li>If the cluster resource group is active, the last device entry cannot be
removed. The cluster resource group must be ended first.</li>
</ol>
This API operates in an asynchronous mode. See <a href=
"clust1a3.htm#HDRASYMOD">Behavior of Cluster Resource Services APIs</a> for more
information.
<p><strong>Restriction:</strong> This API cannot be called from a cluster
resource group exit program.<br>
</p>
<h3>Authorities and Locks</h3>

</dd>
<dt><strong>Configuration object entry information</strong></dt>
<dd>INPUT; CHAR(*)

cluster resource group. For more information, see <a href="#HDRRGDIC01">Device
Resiliency (RGDR0100 Format)</a>.</p>
</dd>
<dt><strong>Format name</strong></dt>
<dd>INPUT; CHAR(8)
<p>The content and format of the configuration object information. The possible
format names are:</p>
<table cellpadding="5">

<br>
</dd>
<dt><strong>Results information</strong></dt>
<dd>INPUT; CHAR(30)
<p>This parameter identifies a qualified user queue field and is followed by a
reserved field.</p>
<p>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 <a href="#usage_notes">
Usage Notes</a> 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.</p>
<p>Reserved: The last 10 characters of the 30-character results information are
reserved. Each character in this field must be set to hexadecimal zero.</p>
</dd>
<dt><strong>Error code</strong></dt>
<dd>I/O; CHAR(*)
<p>The structure in which to return error information. For the format of the
structure, see <a href="../apiref/error.htm#hdrerrcod">Error Code Parameter</a>.</p>
