Tip:  The chhwres  commands are given in Table 6-24 as examples, but it is not necessary for the user to run these commands. These commands are embedded in to the ROHA run time, and run as part of the ROHA acquisition and release steps. 

A timeout is set with the -w  option, and the timeout is set to the configured value at the cluster level (DLPAR operations timeout) with an extra minute per gigabyte. So, for example, to release 100 GB, if the default timeout value is set to 10 minutes, the timeout is set to 110 minutes (10 + 100). 

For large memory releases, for example, instead of making one 100 GB release request, make 10 requests of a 10 GB release. You can see the logs in the hacmp.out  log file. 

## 6.7.3 Identifying the resources to release 

Figure 6-33 shows three cases of DLPAR, CoD, and EPCoD release for memory and processors. 

At release, the de-allocation order is reversed. On/Off CoD resources are preferably released, which prevents the user from paying for extra costs.
