Preparing to install Infrastructure Management in high availability 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 the Microsoft Clustering software is installed on both the primary and the secondary computers.
Ensure that you add the common logical IP address/host name to be allocated to the two computers to the domain name service (DNS).
Map the disk to be shared between the two computers with the same directory name and/or directory path on both the computers.
The IP address, disk, and network name must be present in the same group.
Ensure that your cluster is configured correctly by running the hostname command 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.
