Certain Simpana packages can be associated with a virtual IP, or
in other words, installed on a "virtual machine" belonging to
some cluster. At any given time the virtual machine's services
and IP address are active on only one of the cluster's servers.
The virtual machine can "fail-over" from one server to another,
which includes stopping services and deactivating IP address on
the first server and activating the IP address/services on the
other server. Currently you have Simpana installed on physical
node angel.company.com.
Now you have a choice of either adding another package to the
existing installation or configure Simpana on a virtual machine
for use in a cluster.
1) Add another package to angel.company.com
2) Install Simpana on a virtual machine
3) Exit

Installing CommVault agent: Clustered environment (NSS-HA)
Verify that NSS-HA stack is installed, configured, and operational. Follow the previous procedure “A.2.
Install CommVault Agent: Interactive Install”, making sure to install on the ACTIVE node FIRST and
selecting to install the File System iDataAgent as virtual on each node of the cluster (Step 6 above).
Each node within a cluster, whether active or passive, must have the necessary software components
installed. Installing these software components to be cluster-aware involves both the active and
passive nodes, whether the software component is installed directly to a particular physical node or
not. During the cluster server installation, software binaries are installed on all physical nodes in the
cluster, and the configuration files on all physical nodes are edited to include information about all
installed cluster servers.
Note the following guidelines:
 Dell recommends that you install the MediaAgent or Agent software for the cluster server on the
active node first.
 You can perform software installation and configuration for all available preferred nodes
automatically when you install the software from a physical node to the cluster server.
 You can subsequently install the software on any passive node that was unavailable during the
automated installation.
 Install the MediaAgent software on the physical node. When you install the MediaAgent software on
the physical node, you can use GridStor
® to provide the necessary failover capabilities. See
CommVault documentation on Alternate Data Paths (GridStor) - Clustered Environments for more
information.
 Install the MediaAgent software from the active node to the cluster server to take advantage of
failover protection provided by the clustering software. You should perform this installation with
all passive nodes available, so the software installs on all nodes in the cluster at once. If any
passive node is not available during the installation, perform a separate passive node installation.
