If you plan to install the Commvault software in a predefined directory or mount point, all software files are copied to the commvault subdirectory. For example, if your predefined directory or mount point is /opt/sw, the software files are copied to /opt/sw/commvault. Therefore, ensure that your predefined directory structure does not contain the commvault subdirectory.
By default, the software binaries are installed in the /opt/commvault directory. During a remote installation, if the installation program detects an existing directory, then the program performs the following actions:
-
Treats the directory as an existing Commvault instance.
-
To avoid overwriting the existing software files, the program creates a new directory (with a number appended) to install a new instance. For example, if you install a second instance, the new instance is installed in /opt/commvault2.
