Error while changing the CPU cores value on ODA
Error received while changing the CPU cores value on ODA machine.
Note: For changing CPU core values reboot is required
| [root@ODA_SRVR ~]# odacli update-cpucore -c 6
Modifying the enabled number of CPU requires a reboot of all nodes in the ODA system. Are you sure you want to proceed with this operation? (Y/N): y DCS-10045:Validation error encountered: reduction in number of cores is not supported. |
Troubleshooting:
| [root@ODA_SRVR ~]# odacli list-cpucores |

From the above commands output ,Means you have already increased value from 6 to 12 , now again you are giving value 6 ,hence you are getting error
Solution:
Need to use force key word at the end.

WARNING: Reducing the number of enabled cores may set offline any of the CPUs used by a CPU Pool. Thus, please review the status of all the CPU Pools after this operation using the ‘describe-cpupool’ command. In case of any CPU from a CPU Pool was offline please run ‘remap-cpupools -f’ to update the list of CPUs and use only online CPUs.
WARNING: All the nodes in this ODA system will reboot after this operation has completed.
