<p>The Add Cluster Resource Group Device Entry (ADDCRGDEVE) command is used to add one or more configuration objects representing resilient hardware devices to a device cluster resource group. All devices being added must be able to be switched from one cluster node to another. When the cluster resource group is switched over or failed over to the first backup system, all devices in the device list are moved to the backup system.
|
|
</p>
|
|
<p>If the cluster resource group contains any members of an auxiliary storage pool group, it must contain <b>all</b> members before the cluster resource group can be started. All members do not have to be specifed at once. Additional members can be added later. If the auxiliary storage pool group has previously been created and clustering can determine which members are in the group, a warning message is sent if some members of the group were not added.
|
|
</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 Add Device Entry on all active nodes in the recovery domain. The cluster resource group status is set to Add Device Entry Pending. If the exit program completes successfully, the cluster resource group status is reset to its value at the time the command 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.
|
|
</p>
|
|
<p><b>Restrictions:</b>
|
|
</p>
|
|
<ol>
|
|
<li>You must have input/output system configuration (*IOSYSCFG) special authority to run this command.
|
|
</li>
|
|
<li>This command cannot be called from a cluster resource group exit program.
|
|
</li>
|
|
<li>Cluster Resource Services must be active on the node processing the request.
|
|
</li>
|
|
<li>The number of configuration objects being added plus the number of configuration objects already in the cluster resource group cannot exceed 256.
|
|
</li>
|
|
<li>The configuration objects being added cannot be specified in another cluster resource group.
|
|
</li>
|
|
<li>If the primary node does not currently own the specified devices, the command fails with an error message.
|
|
</li>
|
|
<li>All nodes in the recovery domain must be active.
|
|
</li>
|
|
<li>For the configuration objects specified:
|
|
<ol>
|
|
<li>Only auxiliary storage pool devices are supported.
|
|
</li>
|
|
<li>You must create the configuration object for the devices being added on all nodes in the recovery domain of the cluster resource group.
|
|
</li>
|
|
<li>The resource name specified in the configuration object must be the same on all nodes in the recovery domain.
|
|
</li>
|
|
<li>Devices attached to the same IOP or high-speed link I/O bridge can be specified for only one cluster resource group.
|
|
</li>
|
|
<li>If devices attached to different IOPs or high-speed link I/O bridges are grouped such as for an auxiliary storage pool, all devices for the affected IOPs or high-speed link I/O bridges must be specified in the same cluster resource group.
|
|
</li>
|
|
<li>The IOP or high-speed link I/O bridge controlling the devices specified in a cluster resource group must be accessible by all nodes in the cluster resource group's recovery domain. This is verified if sufficient hardware configuration has been performed so that all nodes are aware of the new hardware. If hardware configuration is incomplete, this is verified when the Start Cluster Resource Group (STRCRG) command is called.
|
|
</li>
|
|
<li>If a data base name is specified in the configuration object, it must be the same on all nodes in the recovery domain.
|
|
</li>
|
|
<li>If a new auxiliary storage pool group is added to an active cluster resource group, all members of the auxiliary storage pool group must be specified.
|
|
</li>
|
|
<li>If a server takeover IP address is specified, it must exist on all nodes in the recovery domain if the cluster resource group is active. The server takeover IP address must be unique within the cluster. It can only be associated with a primary auxiliary storage pool.
