There is a USM in CC project. Customer provide one server and huawei install USM on this server. After installation, imu process on USM cann't run.
login USM as "root", run "ps -ef | grep imu". There is no imu in running status.
On USM server, get following logs:
RD analysis logs, find problem is that CPU core is 80.
The CPU core of USM server must be greater than 8 and less than 32.
So we set CPU running core is 20 on server BIOS. After setting, imu process is in running and USM is ok.
If customer provide USM server, please confirm CPU core is greater than 8 and less than 32.
By the way, memory is 32GB at least.
