If you do not include a location specifier in the location field, the DARE 
Resource Migration utility performs a default migration, again making the 
resources available for reacquisition.

Stop Location
The second special location keyword, 

stop

, causes a resource group to be 

made inactive, preventing it from being reacquired, though it remains in the 
resource configuration. Its resources remain unavailable for reacquisition 
even after a failover or reintegration.

8.5.3.3  Using the cldare Command to Migrate Resources
The 

cldare

 command can be used to perform dynamic resource group 

migrations to other cluster nodes in conjunction with other 

cldare 

resource 

functionality. It lets you specify multiple resource groups and nodes on the 
command line, as long as the final resource group configuration is consistent. 
After some error checking, the resources are released and reacquired by the 
specified cluster nodes. Resource migration first releases all specified 
resources (wherever they reside in the cluster); then it reacquires these 
resources on the newly specified nodes.

You can also use this command to swap resources on nodes in the resource 
group’s node list, but you cannot mix keywords—

default, stop,

 and 

node

—when using the 

cldare

 command.

To migrate resource groups (and their resources) using the

 cldare

 command, 

enter the following command:

where 

-M

 specifies migration, and where resource group names must be valid 

names of resource groups in the cluster. You can specify a node name (or 
special location) or the keyword 

stop

 or 

default

 after the first colon. The node 

name must represent a cluster node that is up and in the resource group’s 
node list. You can specify a migration type after the second colon. Repeat this 
syntax on the command line for each resource group you want to migrate. Do 
not include spaces between arguments.

A default migration can be used to start a cascading resource group that 
has INACTIVE_TAKEOVER set to false and that has not yet started 
because its primary node is down.
