The Cluster Infrastructure SPI helps administrators monitor HA cluster (or fail over cluster) infrastructure on the network. The features provided by the SPI are detailed below:
The System Infrastructure SPI service discovery policy is deployed to the nodes when new cluster nodes are added in HPOM for Windows. It discovers the systems infrastructure on the node.
The system discovery is not deployed automatically in case of HPOM for UNIX and Linux. Also, in case of existing nodes in HPOM for Windows discovery policy is not autodeployed. You must manually deploy the following policies before you manually deploy the discovery policy. The cluster member nodes must already be added in the HPOM node bank before running discovery policy.
The Systems Infrastructure service discovery identifies the cluster nodes and initiates the deployment of Cluster Infrastructure discovery policy on the nodes. The Cluster Infrastructure discovery discovers the clusters, cluster nodes, and resource groups.
Deploy the following policies on managed node:
• InfraSPI-Messages policy - To access this policy select Policy management >Policy groups> SPI for Infrastructure > en > Messages
• SI-SystemDiscovery policy - To access this policy select Policy management > Policy groups > SPI for Infrastructure > en > Systems Infrastructure > AutoDiscoveryDeploy the following policy on managed node on management server:
InfraSPI-ServerSetting policy - To access this policy select Policy management > Policy groups > SPI for Infrastructure > en > Settings and Thresholds > Server Settings
To access these policies select Policy management > Policy groups > SPI for Infrastructure > Settings and Thresholds > Agent Settings
Instructions for installing the Smart Plug-in for Cluster Infrastructure are documented in the following guide provided in PDF (.pdf) format:
Before installing the Cluster Infrastructure SPI, make sure that the following requirements are met. For the installation requirements for the management server, see the HP Operations Manager Release Notes.
HPOM management server requirements:
HPOM managed node requirements:
Disable Autodeployment on DCE agents
If you add a new node running DCE agent in the HPOM for Windows node bank, ensure that auto-deployment is disabled for the node. To disable autodeployment on DCE agents, follow these steps:
Repeat step 1 to step 5 for all managed nodes running DCE agents.

Open issues in this release:
Advanced Monitoring policies modified in HPOM for UNIX Admin GUI fail to run after deployment to managed nodes.
When advanced monitoring policies are edited in GUI mode in HPOM for UNIX policy editor, syntax errors are induced into the Perl code module (CR ID: QCCR1A96995). This causes the policy to fail to execute. Errors such as the following appear:
"An error occurred in the processing of the policy 'SI-LinuxSshdProcessMonitor'. Please check the following errors and take corrective actions. (OpC30-797)
Error during evaluation of threshold level "Processes - Fill Instance list" (OpC30-728)
Execution of instance filter script failed. (OpC30-714)
Perl Script execution failed: syntax error at PerlScript line 11, near "1
#BEGIN_PROCESSES_LIST
#ProcName=/usr/sbin/sshd
#Params=
#Params=
#MonMode=>=
#ProcNum=1
#END_PROCESSES_LIST
@ProcNames"
Missing right curly or square bracket at PerlScript line 17, within string
syntax error at PerlScript line 17, at EOF
. (OpC30-750)"The un-edited advanced monitoring policies (Measurement Threshold type) work fine when deployed from HPOM for UNIX.
Workaround: To edit the settings in the Measurement Threshold policy, use ‘Edit in Raw mode’ feature of the HPOM for UNIX Admin GUI to change the policy contents. This requires you to know the syntax of the policy data file.
Infrastructure SPI fails to log data as expected on nodes running MC/ServiceGuard cluster nodes that are offline
Due to limitations in cluster awareness feature of the HP Operations Agent, the Cluster Infrastructure SPI fails to log data as expected on nodes running MC/ServiceGuard cluster which are offline. On other nodes that are online, data logging happens correctly. This behavior affects only the reports and do not affect the monitoring of clusters. For more details on the HP Operations Agent limitations in cluster awareness, see the CR QCCR1A95238 "ovclusterinfo -a" wrongly shows cluster status on MCSG RHEL5.3 IA64 based cluster nodes.
Auto-node addition failure.
The auto-addition of nodes generates message alerts. In case of success these messages are automatically acknowledged. In case of failure you can notice a "(F)ailed" under automatic command in the HPOM console, and see the generated error message.
Workaround: In case of failure view the instructions from the message and take appropriate steps.If the expected set of host nodes or resource groups do not appear in the HPOM for Windows node bank, refer to the CR ID: QCCR1A95491for the solution. HPOM for UNIX and HPOM for Linux are not affected by this issue.
Infrastructure SPIs Measurement Threshold policies that use perl modules like OvTrace.pm, OvPrum.pm, etc do not work on x64 systems.
Workaround: Use MGD_NODE_INSTRUMENTATION_DIR config variable in eaagt namespace. This must be used in addition to OPC_PERL_INCLUDE_INSTR_DIR.
Example:
[eaagt]
OPC_BUFLIMIT_SEVERITY=major
OPC_BUFLIMIT_SIZE=10000
OPC_HBP_INTERVAL_ON_AGENT=-1
OPC_INSTALLATION_TIME=7/9/2009 2:38:14 AM
OPC_INSTALLED_VERSION=08.60.005
OPC_IP_ADDRESS=192.168.0.0
OPC_NODENAME=YexampleY.com
OPC_NODE_CHARSET=utf8
OPC_PERL_LIB_DIR=C:\Program Files\HP\HP BTO Software\\nonOV\perl\a\lib
OPC_PERL_INCLUDE_INSTR_DIR=TRUE
MGD_NODE_INSTRUMENTATION_DIR=C:\ProgramData\HP\HP BTO Software\bin\instrumentation
Alert Messages while the System Discovery automatically adds nodes
While system discovery automatically adds nodes for cluster and virtualized environments, it generates alert messages with normal severity. These messages run automatic actions to re-classify the managed node based on operating system specific node groups in the HPOM node bank. Once the auto-action for each message completes the message is auto-acknowledged. As long as the action is running the message action status is shown as 'R' (running state). If the action fails to run for any reason, the status is shown as 'F' and the message is not auto-acknowledged. Appropriate actions are listed in the instructions for the alert in case of failure. Sample of such messages -
Auto-Add linux-vma.ovtest.com:VMware vMA:InfraSPI Managed Nodes
Auto-Add WIN2k3.ovtest.com:MS Windows:InfraSPI Managed NodesMessages with auto-actions for auto-adding all cluster nodes and resource groups are generated if the node is a clustered node. These messages too, are auto-acknowledged if the actions run successfully. It is possible to prevent cluster resource groups from getting added in the node bank setting the XPL configuration setting infraspi.AutoAdd_Cluster_RG_IP=false. If all the nodes in a cluster are already in the node bank as controlled nodes, these nodes are regrouped in a cluster-based classification. If some nodes in the cluster are not in the node bank, SNMP nodes/Message allowed nodes are created with node IP address set to the same IP address as the cluster node. This is to assign messages to the cluster node.
If you want you can disable the Auto-addition feature by changing the default value of the following XPL configuration parameters:
Configuration Parameters Default Value Value to disable auto addition AutoAdd_ClusterNode true false AutoAdd_Cluster_RG_IP true false
