Installing Solaris Resource Manager on an Existing Sun Cluster

When installing the Solaris Resource Manager product on an existing Sun Cluster, consider the following guidelines.

• Before you install the Solaris Resource Manager product on a node that is part of an existing cluster, the Sun Cluster product should already be installed and fully functional on all nodes of that cluster, using the installation procedures described in the Sun Cluster documentation.

• Once Sun Cluster is correctly installed, boot each node on which you plan to install Solaris Resource Manager in non-cluster mode. The Solaris Resource Manager installation procedure requires a reboot of each node. For more information about rebooting a cluster node in non-cluster mode, see the Sun Cluster 3.0 12/01 System Administration Guide.

• To ensure continuous availability of applications during Solaris Resource Manager installation, install it on one node at a time. Before installing Solaris Resource Manager on a node, switch over all of that node's applications to a backup node. For more information about switching the current primary of a resource group, see the Sun Cluster 3.0 12/01 Data Services Installation and Configuration Guide.

• If your cluster includes Sun Enterprise 10000 machines, you must install Solaris Resource Manager on each domain in which you want Solaris Resource Manager functionality.

• The Solaris Resource Manager limits database files (/var/srm/srmDB) do not need to be identical on all nodes. See the section "Configuring Solaris Resource Manager in Sun Cluster 3.0 Update Environments" in "Advanced Usage" in Solaris Resource Manager 1.3 System Administration Guide.

• Installation of Solaris Resource Manager on a two-node Sun cluster should take less than 30 minutes. Exact installation times vary depending on the number of nodes, number of file systems, and speed of the systems.

There are no other special requirements.
