CEC Agent (PK) Setup

A CEC (Central Electronic Complex) is, for our monitoring purposes, a p595 frame .

The CEC agent is pre-installed with the VIOS software so only needs to be configured.

The CEC agent needs to run on the frame it is monitoring, so has been configured on one of the DEV VIOS servers on each frame (VIOS1SD).

1. Login as padmin to the VIOS server (e.g b0038-vios1sd).

2. List available agents on the VIOS server:

$ lssvc

3. List configuration information for the CEC agent:

$ cfgsvc –ls ITM_cec
HOSTNAME
MANAGING_SYSTEM
CEC
DIRECTOR_HOST_ADDRESS
DIRECTOR_AUTHENTICATION
DIRECTOR_PORT_NUMBER
RESTART_ON_REBOOT
MIRROR

4.Set the configuration values for the agent (DIRECTOR values are not required):

$ cfgsvc ITM_cec -attr Restart_On_Reboot=true hostname=itmprtem.unix.brm.pri
  managing_system=hmc2.brm.pri CEC=Server-9119-595-3-SN836830F mirror=itmprtemf.unix.brm.pri

5. On the HMC to get the authkey for the agent:

viosvrcmd -m Server-9119-595-3-SN836830F -p B0038-VIOS1SD -c "cfgsvc -key ITM_premium"

6. On the HMC add the authkey to the HMCs authorized_keys2 file:

$ mkauthkeys --add 'output from viosvrcmd'

7. On the VIOS server ensure that the known_hosts file exists with the correct permissions.

$ touch /home/padmin/.ssh/known_hosts
$ chown padmin:system /home/padmin/.ssh/known_hosts
$ ssh hscroot@hmc2.brm.pri (and confirm the ssh prompt)

8. On the VIOS server update the /opt/IBM/ITM/config/pk.ini file to add the following lines for agent autonomy mode:

CTIRA_RECONNECT_WAIT=600
CTIRA_PRIMARY_FALLBACK_INTERVAL=1500

9. On the VIOS server start the agent

$ startsvc ITM_cec
Starting Premium Monitoring Agent for VIOS ...
Premium Monitoring Agent for VIOS started

The startup may complain about being unable to establish authenticity but the agent but should still start.
