IBM Power HMC Preparations

Ensure you have correct date/time and NTPd running to keep it accurate!

Login to your HMC
Navigate to Console Settings
- Go to Change Date and Time
  - Set correct timezone, if not done already
  - Configure one or more NTP servers, if not done already
  - Enable the NTP client, if not done already
Navigate to Users and Security
- Create a new read-only/viewer hmci user, which will be used to connect to the HMC.
- Click Manage User Profiles and Access, edit the newly created hmci user and click User Properties:
  - Set Session timeout minutes to 60
  - Set Verify timeout minutes to 15
  - Set Idle timeout minutes to 90
  - Set Minimum time in days between password changes to 0
  - Enable Allow remote access via the web
Navigate to HMC Management and Console Settings
- Click Change Performance Monitoring Settings:
  - Enable Performance Monitoring Data Collection for Managed Servers: All On
  - Set Performance Data Storage to 1 day or preferable more

If you do not enable Performance Monitoring Data Collection for Managed Servers, you will see errors such as Unexpected response: 403.

Use the HMCi debug option (--debug) to get more details about what is going on.

Configure date/time through CLI

Example showing how you configure related settings through the HMC CLI:

chhmc -c date -s modify --datetime MMDDhhmm           # Set current date/time: MMDDhhmm[[CC]YY][.ss]
chhmc -c date -s modify --timezone Europe/Copenhagen  # Configure your timezone
chhmc -c xntp -s enable                               # Enable the NTP service
chhmc -c xntp -s add -a IP_Addr                       # Add a remote NTP server

Remember to reboot your HMC after changing the timezone.
