Continued from Installation of HPOM agent from local files

Step 1: create a tar file for the agent or mount the ISO image

Download ISO image for agents from HP.

# ll  Software_HP_Operations_Agent_v11.00_LINUX_TC097_15002.iso
-rw-r--r-- 1 root root 186165248 2012-04-23 11:43 Software_HP_Operations_Agent_v11.00_LINUX_TC097_15002.iso

Step 2: mount ISO image and copy its content to the directory create in /tmp (or /var) directory

mount -o loop /tmp/Software_HP_Operations_Agent_v11.00_LINUX_TC097_15002.iso /mnt
mkdir /tmp/Agent11
cd /tmp/Agent11
cp -r /mnt/* .

Step 3: Verify preconditions

To install the agent version 11 and configure the agent with an HPOM management server, you need to use command  oainstall.sh which is available from the ISO media root.

  1. Verify that the node was already created

     
  2. Check if you can communicate with the server using DNS name and hostname (it might make sense to add hostname of the server to /etc/hosts file)
     
  3. Check if the node meets the installation prerequisites, you run (as root) the prerequisite check before installing the product.
    ./oainstall.sh -install -agent -precheckonly

    The command output shows a report on the prerequisite check.

    Step 4: Install the agent using  oainstall.sh

  4. Install the agent and configure the agent with an HPOM management server, run the following command from the media root:
    ./oainstall.sh -install -agent -srv <management_server>

    You can omit certificate server parameter if it is identical to HPOM server. Otherwise run

    ./oainstall.sh -i -a -s <management_server> -cs <certificate_server>
  5. Grant certificate request if one exists
  6. Check the node view -- Certificate state should be installed.

    TIPS:

    1. SLES 10 SP3. On older version of Suse like SLES 10 SP3 you need to install additional libraries. Otherwise you will get an error:
      [04/23/12 12:04:54] [oasetup] [oasetup] [INFO] Checking if the component package HPOvEaAgt is installed on this system.
      error: Failed dependencies:
              libstdc++.so.5 is needed by HPOvPerfMI-11.00.044-1.x86_64
              libstdc++.so.5(CXXABI_1.2) is needed by HPOvPerfMI-11.00.044-1.x86_64
              libstdc++.so.5(GLIBCPP_3.2) is needed by HPOvPerfMI-11.00.044-1.x86_64
    2. SLES 11 SP2. In case of Suse 11 SP2 the following trick is needed to install the agent (assuming agent is unpacked or ISO copied to /tmp/ISO).

      Edit the file /tmp/ISO/packages/LIN/Linux2.6_X64/oareqcheck.cfg replacing in section for SLES 11 2.6 with 3.0

      # SLES 11.x (2.6) 64 bit
          [VER] SLES[2.6]_64b
          [AGT_BIN_FRMT] x64
          [AGT_COMM_TYPE] HTTPS
          [OVM] ( , 36, "SuSE Server 10 (2.6)")
          [SELF]
            [EXE_AND]
              [EXE] cat /etc/SuSE-release | grep -i "SUSE LINUX Enterprise Server" | awk '{print $5;}'
              [CMP] eq
              [VAL] 11
              [EXE] uname -r | awk '{split($0, ar, "."); print ar[1] "." ar[2];}'
              [CMP] eq
              [VAL] 2.6
            [/EXE_AND]

      The result should be:

      # SLES 11.x (2.6) 64 bit
          [VER] SLES[2.6]_64b
          [AGT_BIN_FRMT] x64
          [AGT_COMM_TYPE] HTTPS
          [OVM] ( , 36, "SuSE Server 10 (2.6)")
          [SELF]
            [EXE_AND]
              [EXE] cat /etc/SuSE-release | grep -i "SUSE LINUX Enterprise Server" | awk '{print $5;}'
              [CMP] eq
              [VAL] 11
              [EXE] uname -r | awk '{split($0, ar, "."); print ar[1] "." ar[2];}'
              [CMP] eq
              [VAL] 3.0
            [/EXE_AND]

      after that you can install the agent on SLES 11 SP2

Step 5: Verify the status of the agent

After the installation complete (it usually takes several minutes) you need to verify the status of the agent

# opcagt -status
scopeux     Perf Agent data collector                        (2251)   Running
midaemon    Measurement Interface daemon                     (2163)   Running
ttd         ARM registration daemon                          (32369)  Running
perfalarm   Alarm generator                                  (2522)   Running
perfd       real time server                                 (2148)   Running
coda        OV Performance Core                 COREXT       (2459)   Running
opcacta     OVO Action Agent                    AGENT,EA     (2445)   Running
opcmsga     OVO Message Agent                   AGENT,EA     (2420)   Running
opcmsgi     OVO Message Interceptor             AGENT,EA     (2409)   Running
rtmd        HP Real Time Measurement            AGENT        (2347)   Running
Message Agent is not buffering.

Generally agent should be running after the installation without any crashed daemons. It is not running or some daemons fail that's the sign of trouble. You can try to start the agent manually using command

ovc -start 

Note: Put the path in front or add /opt/OV/bin/:/opt/OV/bin/OpC/ to the PATH before issuing the command.

Step 6: Create certificates and grant them on the HPOM server

Typically installation of agent version 11 install certificate as well and you do not need to take any additional action.

If this is not true and certificate is not installed you need to check if certificates are available and if status is "pending" you need to grant them using Admin GUI:

/opt/OV/bin/ovcert -list

To check the status of the request

/opt/OV/bin/ovcert -status

If there is no pending certificate request you need to execute

/opt/OV/bin/ovcert -certreq

and repeat the check of the status using /opt/OV/bin/ovcert -status

If status is pending you can grant the request either using command line tools or the Admin UI.

Then verify that the certificates are available using the command on the node:

# /opt/OV/bin/ovcert -list

After that you should check if the node is listed with certificate installed in view mode of the AdminGUI. If not verify communications using command

# /opt/OV/bin/OpC/opcagt -status usa12

You can also send a test message to the server by deploying opcmsg policy and using the command opcmsg.
