VIOS Agent (VA) Setup

The VIOS agent is already installed as part of VIOS. Changes to the configuration are performed on the VIOS server itself.

IBM PMR 00078 currently open for VIOS agent as this is not returning data for most installs.

1. Login as padmin to the VIOS server (e.g b0017-vios1sd).

2. List available agents on the VIOS server:

$ lssvc

3. List configuration information for the VIOS agent:

$ cfgsvc –ls ITM_premium

4. Set the configuration values for the agent:

$ cfgsvc ITM_premium -attr Restart_On_Reboot=true hostname=itmprtem.unix.brm.pri
  managing_system=hmc1.brm.pri

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

viosvrcmd -m Server-9119-595-1-SN83724B2 -p B0017-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@hmc1.brm.pri (and confirm the ssh prompt)

8. On the VIOS server update the /opt/IBM/ITM/config/va.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_premium

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

10. See the example below for setup on B0017-VIOS2SD:

ON VIOS SERVER:

$ lssvc
ITM_premium
ITM_cec
TSM_base
ITUAM_base
TPC_data
TPC_fabric
DIRECTOR_agent
perfmgr
ipsec_tunnel

$ cfgsvc -ls ITM_premium
MANAGING_SYSTEM

RESTART_ON_REBOOT
  
$ cfgsvc ITM_premium -attr Restart_On_Reboot=true hostname=itmprtem.unix.brm.pri
  managing_system=hmc1.brm.pri mirror=itmprtemf.unix.brm.pri
