Installing the BMC TrueSight Infrastructure Management Server in HA mode on Linux/Solaris

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

The following applications are required to control high-availability for Infrastructure Management on Linux/Solaris operating systems:

• Sun Cluster software for Solaris
• Red Hat Availability add-on for Linux (with Resilient Storage add-on if GFS2 is required)

Prerequisites to installing Infrastructure Management in HA mode

The following are the prerequisite tasks that you must perform before installing Infrastructure Management in HA mode:

• Ensure that the cluster configuration is of ‘node and cluster disk majority’ type.
• Ensure that the cluster name does not contain an underscore (_).
• Ensure that a visible quorum disk is available.
• Ensure that the HA installer files are not copied to the shared disk.
• Ensure that you have the identical operating system version (for example, Windows 2008 Enterprise Server) on the primary and the secondary computers.
• Ensure that you have identical hardware configuration on the primary and the secondary computers.
• Ensure that the primary and the secondary computers are located in the same domain.
• Configure the logical IP address.
• Ensure that the primary and the secondary computers 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.
• Ensure that your cluster is configured correctly by running the hostnamecommand in a command prompt window.
• For HA installations on Solaris systems, ensure that this command returns the virtual host name and not the physical host name.

Installing the BMC TrueSight Infrastructure Management Server in HA mode on Linux/Solaris systems

The following procedure explains how to install the BMC TrueSight Infrastructure Management Server in HA 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.  

2. (Solaris only) Change the ip address of the primary node to the logical IP address configured for the cluster by entering the following commands:
   

   ifconfig <alias interface> plumb

   example: ifconfig hme0:1 plumb

   ifconfig <alias interface> <logical ip> netmask <netmask> up

   example: ifconfig hme0:1 10.129.5.252 netmask 255.255.252.0 up
   

3. 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.
4. 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.  

5. (Solaris only) After successful installation of the BMC TrueSight Infrastructure Management Server, change the logical IP address back to the IP address of the primary node by entering the following command from a command line:

   ifconfig <alias interface> down

   example: ifconfig hme0:1 down

   ifconfig <alias interface> unplumb

   example: ifconfig hme0:1 unplumb 

6. (Linux only) 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
7. 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
