Note:  The Approaching out of compliance  status is a normal status in the Enterprise Pool, and it is useful when you need extra resources temporarily. The PowerHA SystemMirror RG takeover scenario is one of the cases. 

## Log information in the hacmp.out file 

The hacmp.out  log file records the process of the RG offlining, as shown in Example 6-20.

During the release process, the de-allocation order is EPCoD and then the local server’s free pool. Because EPCoD is shared between different servers, the standby node on other servers always needs this resource to bring the RG online in a takeover scenario. 

## Resources online at the standby node (ITSO_S2Node1) 

In this case, the RG online on standby node does not need to wait for the DLPAR to complete on the primary node because it is an asynchronous process. In this process, PowerHA SystemMirror acquires a corresponding resource for the onlining RG. 

Note:  Before acquiring the process start, the 2C and 30 GB resources were available in the Enterprise Pool, so this kind of resource can also be used by standby node.
