This topic provides instructions to install the TrueSight Infrastructure Management Server in high availability cluster mode on Linux operating systems.

The following application is required to control high-availability for Infrastructure Management on Linux operating systems:

Red Hat Availability add-on for Linux (with Resilient Storage add-on if GFS2 is required)

Note

Infrastructure Management is not supported on VMware with VMWare Fault Tolerance (FT) as Infrastructure Management high availability support.

Prerequisites to installing Infrastructure Management in HA OS cluster mode

Ensure that the following prerequisite tasks are performed or checked before installing Infrastructure Management in HA OS cluster mode:

  • A visible shared disk should be available and you choose the shared drive as the installation directory.
  • The operating system version must be identical on the primary and the secondary computers.
  • The hardware configuration must be identical on the primary and the secondary computers.
  • The primary and the secondary computers must be located in the same domain.
  • Configure the logical IP address.
  • The primary and the secondary computers must have identical time stamps.
  • Ensure that you add the common logical IP address/host name to be allocated to the two computers to the domain name service (DNS).
  • Mount the disk to be shared between the two computers with the same directory name and/or directory path on both the computers.

To install the Infrastructure Management Server in HA OS cluster mode on Linux systems

The following procedure explains how to install the BMC TrueSight Infrastructure Management Server in HA OS cluster mode on primary and secondary servers:

  1. Change the host name of the primary node to the logical host name configured for the cluster by entering hostname logicalHostName.
    For example, hostname bmccluster.bmc.com.
  2. Install BMC TrueSight Infrastructure Management Server on the primary node.
    During the installation, choose the cluster file system (/global) that is shared on both nodes as the installation location.
    The installation is completed successfully.

  3. After successful installation of the BMC TrueSight Infrastructure Management Server, change the logical host name back to the host name of the primary node by entering hostname  
    primaryHostName.  
  4. On the primary node, remove the following files so that the Infrastructure Management application does not start:

    • /etc/rc3.d/S81BMCTrueSight
    • /etc/rc0.d/K09BMCTrueSight
    • /etc/rc1.d/K09BMCTrueSight
  5. Add the BMC TrueSight Infrastructure Management Server component (logical host name) with BMC TrueSight Presentation Server. Make sure that the status of all BMC TrueSight Infrastructure Management Server component is Connected. 
  6. Stop all processes on the primary node. Use the following command:
    pw sys stop.

  7. Move the shared disk from primary node to the standby node. Use one of the following commands:
    (For RHEL 6.x) clusvcadm -r logicalhostname -n Standbymodehostname
    (For RHEL 7.0) pcs resource move <resource group name> Standbymodehostname
    Do not execute the above commands on the shared disk. 
     

    Note

    You can use the following command to find the resource group name on the primary host:

    pcs status

  8. On the standby node, create the required links for the BMC TrueSight Infrastructure Management Server by entering the following commands:
    • ln -s /serverInstallDirectory/pw /usr/pw

    • ln -s /usr/pw/pronto /usr/pronto

    • ln -s /usr/pw/pronto/bin/pw /bin/pw

  9. Start all processes on the standby host. Use the following command:
    pw sys start 
  10. On the standby node, check for the Infrastructure Management Server crontab entries:
    1. Identify the crontab entries by using the crontab -l command and check for all entries between the lines # begin_pronto and # end_pronto
    2. If the crontab entries are missing, open the command prompt, navigate to the <installDirectory>\pw\scripts folder, and run the following command:

      CreateCrontabEntries.sh linux <Database>

      where <Database> can be Oracle or SAP SQL Anywhere
      For example, CreateCrontabEntries.sh linux Oracle

Note

After moving the shared disk from the primary node to the standby node, the status of all BMC TrueSight Infrastructure Management Server components must be Connected on the BMC TrueSight Infrastructure Management Server Registration page.

BMC TrueSight Infrastructure Management Server must successfully connect to Integration Service and PATROL Agent.
