When installing Sun Cluster on nodes that already contain Solaris Resource Manager, consider the following guidelines.
Install Sun Cluster on all nodes, using the installation procedures described in the Sun Cluster documentation.
The Solaris Resource Manager configuration files (/var/srm/srmDB) do not have to be identical on all nodes. See "Configuring Solaris Resource Manager in Sun Cluster 3.0 Update Environments" in Solaris Resource Manager 1.3 System Administration Guide.
Installation times vary, depending on the number of nodes and file systems and the speed of the systems. The presence of Solaris Resource Manager does not lengthen the install time for Sun Cluster.
There are no other special requirements.
