[ROHALOG:2490918:(19.227)] ============ End ============== [ROHALOG:2490918:(19.231)] INFO: received error code 21. [ROHALOG:2490918:(19.233)] No or no more reassessment. [ROHALOG:2490918:(19.241)] An error occurred while performing acquire operation. 252D3145 1109140415 T S mem DR failed by reconfig handler 47DCD753 1109140415 T S PROBEVUE DR: memory remove failed by ProbeVue rec Example 6-47 The errpt error report PowerHA SystemMirror simulates the resource acquisition process based on the current  configuration and generates the log in the  ver_collect_dlpar.log  file. During the process of resource online or offline, the  hacmp.out  and the  async_release.log logs are useful for monitoring or debugging. In some RG offline scenarios, the DLPAR remove  operation is a synchronous process. In this case, PowerHA SystemMirror generates the  DLPAR operation logs in the  async_release.log  file. In a synchronous process, only  hacmp.out  is used. Sometimes, the DLPAR operation fails, and AIX generates some errors that are found in the  errpt output, as shown in Example 6-47. You can identify the root cause of the failure by using this information. You can use the following commands on the HMC to do monitoring or maintenance. For a  detailed description of the commands, see the  man  page for the HMC. This command shows the LPAR minimum, LPAR maximum, the total amount of memory, and  the number of CPUs that are currently allocated to the LPAR values. This command verifies that the LPAR node is DLPAR-capable. This command runs the DLPAR operations on the HMC outside of PowerHA SystemMirror to  manually change the LPAR minimum, LPAR minimum, and LPAR required values for the  LPAR. This command might be necessary if PowerHA SystemMirror issues an error or a  warning during the verification process if you requested DLPAR and CoD resources in  PowerHA SystemMirror. This command shows the system CoD of the current configuration. This command runs the CoD operations on the HMC outside of PowerHA SystemMirror and  manually changes the Trial CoD, On/Off CoD, and so on, of the activated resources. This  command is necessary if PowerHA SystemMirror issues an error or a warning during the  verification process, or if you want to use DLPAR and On/Off CoD resources in PowerHA  SystemMirror.
