Installation of HPOM agent from local files

News HPOM agents Recommended Links opcnode command script Configuration node groups
Installation of agent version 8  Installation of agent version 11 Adding nodes Deinstallation of agent History Humor Etc

This method of installation is different from using Installation of HPOM agent using ssh passwordless login  in several aspects.

Step 1: Check Requirements

You need to check is /opt contains at least 350M of free space. On old servers that can be a problem and you get diagnostics like:

[ PASS  ] Is user root
[ PASS  ] Is Operating system Linux
[ PASS  ] Is architecture X64
[ PASS  ] Check if DCE Agent is not installed
[ FAIL  ] 350 MB free disk space on /opt
         Not enough disk space on /opt. Required is 350 MB, free 64.6992MB.
[ PASS  ] 350 MB free disk space required on /var
At least two ports need to be opened for the installation of the HTTP agent:
  1. Port 383 is used for communication of HTTP agent with the server. 
  2. ssh for transferring files or equivalent ftp/telnet combination.

Step 2: Create a node

Now you need to create a node on HPOM server. This is a very important step and if done incorrectly will create mass of problems in subsequent steps.

You can use GUI or opcnode command on the HPOM server to create a node:

opcnode -add_node \ \
         node_label=usa12 \
         group_name=linux \
         layout_group=linux \
         ip_addr= \
         net_type=NETWORK_IP \

This is a very important step. If you don't do that then the agent will install OK but will not start properly and you have troubles on later steps.

This step is identical to and is better covered in Installation of HPOM agent using ssh passwordless login and script

Step 3: Subsequent steps

Subsequent steps depend on the version of the agent:

[Dec 14, 2010] Agent installation has error from HPOM 9

IT Resource Center forums

Pavel Ch Aug 4, 2009 10:11:58 GMT

Hi All,

I try to install agent (on the Win 2003 and on the SuSe 10.0) from Admin UI of HPOM 9.0.

Installation status has state Failed and Exit Code - "20" in both system.

In the Agent Installation Log appears error:

from SuSe 10.0:
Script /opt/OV/bin/OpC/agtinstall/ invoked by root at 08/04/09
WARNING: Cannot resolve/verify system by asking the name service
(or /etc/hosts).
PHASE I: reading missing passwords for Managed Nodes.
ERROR: Node unknown or not responding.
PHASE II: checking prerequisites for Managed Nodes.
NOTE: Skipping node

from Win 2003:
Script /opt/OV/bin/OpC/agtinstall/ invoked by root at 08/04/09
PHASE I: reading missing passwords for Managed Nodes.
========> Do you want to re-enter the login information for system (y|n=default)?
WARNING: Time out of 1 seconds has occurred during user input.
WARNING: No valid password has been specified for ms/x86/winnt system
ERROR: Skipping node for initial password check;
maybe you know the password later when applying the HPOM software
maintenance on that system.

Ping from server to both nodes successful, is successful too.

Could you help me?

Goran Koruga


It looks like opcping script is failing.

You can debug like so:

cp -i /etc/opt/OV/share/conf/OpC/mgmt_sv/inst_debug.conf /var/opt/OV/share/tmp/OpC/mgmt_sv/inst_debug.conf

Edit the last file and uncomment OPC_DEBUG_LOCAL, OPC_DEBUG_REMOTE and OPC_DEBUG_FILE lines.

Then run and you will get the debugging info in /tmp/

More details are in the 'inst_debug' man page.

You should also look why it failed to resolve the node.

File "/tmp/" contains following:
> cat /tmp/
Script /opt/OV/bin/OpC/agtinstall/ invoked by root at 08/04/09 13:38:41.
HPOM Software Maintenance on Managed Node(s).

Goran Koruga

Doh, I forgot you also have to uncomment OPC_DEBUG_APPEND and OPC_DEBUG_CALLOUT - sorry.


Pavel Ch

Thanks Goran Koruga,

I forgot to start FTP service on the Windows node.

One more question, is it correct - when I install agent to Windows node that HPOM only copy <agent_files> to ftp directory and then I need to manually execute "cscript opc_inst" on the node ?

Goran Koruga


Yes - that is normal. Once you have one Windows OM agent installed you can use that as an Installation Server to install other Windows nodes in an automated way.

But you need permissions sorted for that to work - it's explained in the manuals.
