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. 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. 6.7.3 Identifying the resources to release Figure 6-33 Identifying the resources to release Chapter 6.
