Note: HP renamed the product called now HP operations manager way too many times. Also it is very inconsistent with using abbreviations. Here we will assume that the term "HP Operations manager" and abbreviations HPOM, OMU, and OVO  mean the same thing :-)

Documentation for the command like agent installation is almost incomprehensible as if HP want to generate calls to tech support in each and every more or less non-trivial case. GUI based installation is better for starters.  Even figuring out that the inst.sh script should be used to install the HPOM software on HTTPS  nodes in not trivial thing if you never used HPOM before. It's badly explained in the documentation. Some info is scattered in chapter 9 in Administration UI Administration and Configuration Guide

Procedure for the installation of the HPOM agent is very similar to Tivoli. You need first to create a database record using special command opcnode and then run script inst.sh which asks you several questions and installs the software. After that you need to test the result with the command opcragt. That's the view from 1000 feet. As always the devil is in details.    

To install the HPOM software on HTTPS nodes, using inst.sh script you need to perform three main steps:

  1. Add node to the database with opcnode command This is a required step. Without database record about the node you can't run inst.sh script.
  2. Create a certificate for passwordless SSH login to the selected node (this is optional but very convenient mode; you can also install the agent using  ftp + rsh).
  3. Run the inst.sh script to install the HPOM software on the selected node. Like any command line program it can be scripted using expect (or Perl-expect) but one can also use a response file with the parameter -f.

The directories for agents for supported platforms are as following:

Add node to the database with opcnode command

This is an important prerequisite before usage of inst.sh script. Command  opcnode adds a record about the node to the database. It there are few nodes it is simpler to do this operation via Admin GUI. If there are many nodes to install scripting opcnode is the way to go.

opcnode -add_node node_name=<node_name>  net_type=<network_type> mach_type=<machine_type>

mach_type
mach_type specifies the machine type for a node in the HPOM Node Bank. This attribute is mandatory. If a new introduced platform is not yet known by opcnode, the platform number will be used. Machine types are defined in AgentPlatform files.In HPOM version 9 that following machine types are supported:

 
MACH_BBC_LX26RPM_X64
MACH_BBC_SOL10_X86
MACH_BBC_OTHER_IP
MACH_BBC_LX26RPM_IPF64
MACH_BBC_LX26RPM_X86
MACH_BBC_OTHER_NON_IP
MACH_BBC_WINXP_IPF64
MACH_BBC_HPUX_IPF32
MACH_BBC_HPUX_PA_RISC
MACH_BBC_AIX_K64_PPC
MACH_BBC_AIX_PPC
MACH_BBC_WINNT_X86
MACH_BBC_SOL_SPARC
MACH_BBC_WIN2K3_X64

 

group_name=<group_name> node_type=<node_type>

Optionally you can select the type of managed node with the node_type attribute.

(optional) Enter the desired heartbeat polling settings  by using the opchbp command line utility, for example:

opchbp -interval 0h12m1s <nodename>

Examples

#!/usr/bin/ksh
opcnode -add_node \
    node_name=suse10.softpanorama.org \
    node_label=nti10 \
    group_name=suse \
    layout_group=suse \
    ip_addr=10.10.10.10 \
    net_type=NETWORK_IP \
    mach_type=MACH_BBC_LX26RPM_X64

Create a certificate for passwordless SSH login to the selected node

This step is trivial and is not covered here. You should generally use RSA certificates. Here is the procedure on Solaris for allowing ssh access for root, without a password.  

1.  Configure the server to allow this type of connection:

Check  "/etc/ssh/sshd_config"  to make sure RSAAuthentication is set to "yes":
RSAAuthentication  yes

(If there is a line like  "IdentityFile  ~/.ssh/id_rsa",  make sure it is not commented out.)  

If you made changes to the ssh_config file, restart the "sshd" daemon:
Solaris 9:        /etc/init.d/sshd  restart
Solaris 10:        svcadm  restart  /network/ssh

2.  Create the public key to copy to your target system

Run the command:        ssh-keygen -t rsa         (accept defaults, no passphrase)

That should create a public key file:          ~/.ssh/id_rsa.pub

________________________________________________________________________________

On the target host:

1.  Configure the server to allow this type of connection:

Edit  "/etc/ssh/sshd_config"  to make sure RSAAuthentication and PermitRootLogin are set to "yes":

PermitRootLogin  yes
RSAAuthentication  yes

(If there is a line like  "IdentityFile  ~/.ssh/id_rsa",  make sure it is not commented out.)  

If you made changes to the sshd_config file, restart the "sshd" daemon:
Solaris 9:        /etc/init.d/sshd  restart
Solaris 10:        svcadm  restart  /network/ssh

Copy your public key file over to the target system, and append it to ~/.ssh/authorized_keys        (create the file if it does not exist)

Your connection should now work.

 Run the inst.sh script
to install the HPOM software on the selected node

 

You should first configure the node either using Admin UI or using opcnode command During installation the node automatically sends a certificate request to the certificate server which is automatically granted. If auto-grant is disabled, you need to approve certificate manually.

The inst.sh script performs the following tasks (not necessarily in order):

The script inst.sh is located in the directory /opt/OV/bin/OpC/agtinstall:

/opt/OV/bin/OpC/agtinstall/inst.sh

Here is an example of the agent installation on a Suse 10 SP3 64 bit server

NOTES:  

Defining Common Settings for Managed Nodes

You can define settings on the management server, which are applied to the managed nodes at installation time. Parameters, such as communication ports or http proxy settings, that are used by many nodes can be defined using the file:

/etc/opt/OV/share/conf/OpC/mgmt_sv/bbc_inst_defaults

A sample configuration file with examples of how to set up parameters is available at:

/etc/opt/OV/share/conf/OpC/mgmt_sv/bbc_inst_defaults.sampl

Take a copy of bbc_inst_defaults.sampl , rename it bbc_inst_defaults , and modify in accordance with the syntax specified in the sample file.

Allocate a Specific OvCoreId to a Managed Node

If you want to allocate a specific OvCoreId for a new node, manually add it as follows before starting the agent software installation:

opcnode -chg_id ... id=<id>

or

opcnode -add-node ... id=<id>

During agent installation, the OvCoreId from the HPOM database is used for the specified managed node.

This is recommended when reinstalling a node managed by many management servers. Reusing the original OvCoreId avoids having to update all the HP Operations management servers.

When installing certificates manually, everything is prepared on the HP Operations management server before an agent is installed, including creating an OvCoreId, generate a certificate, add the node with the new OvCoreId to the database. Only after these steps can the agent software be installed on the managed node. Finally the certificate must be copied to the managed node.

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:

Could you help me?

Hello.

It looks like opcping script is failing.

You can debug inst.sh 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 inst.sh and you will get the debugging info in /tmp/inst.sh.2.

More details are in the 'inst_debug' man page.

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

Regards,
Goran

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

Goran

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

Hi.

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.

Goran

Install HP OM Agent on Unix Machine

This is old version 8 installation with nice sceen shots. One importatnt thing to remember is that to install HP OM Agent on Unix Machine ensure the the node host name is resolvable by name service or located in Hosts file

December 18, 2008

Use SSH (Secure Shell) during the installation is very powerful option to insure secure communication in case the client has SSH.

Limit buffer size; it is useful for limiting the buffer size in case of the agent is unable to communicate with the client

to install the agent you can do using command line like

# /opt/OV/bin/OpC/agtinstall/inst.sh <target node>

 

IT Resource Center forums - Agent install fails with ssh access - This thread has been closed

We found that in order to install the OVO agent we had to temporarily re-enable some of the r commands.

1. Add "mgmntsvr_name root" to /.rhosts on the new node. For us our mgmtsvr_name is opscena, so the entry would look like "opscena root".
2. Enable rlogin if it is disabled. In /etc/inetd.conf the new node, uncomment login, shell, exec. Then, run "inetd -c"
3. Try distributing agent to new node.
4. Reverse steps 1 and 2.
