How to increase or decrease CPU count in ODA machine
How to increase or decrease CPU count in ODA machine.
When we received the ODA machine, we get CPU count as follows.
Reboot required? : Yes

For example ,We want to decrease the count to 12(logical) or 6 Physical as per license.
Syntax for changing the CPU count :
odacli update-cpucore -c <value>
Where value is even number.
So the command is as given below
| #odacli update-cpucore -c 6 |
Verify CPU count After Change:
