Before running the pre-installation script, be prepared to answer the following questions:

Is this an upgrade installation?

What local file systems can be used to store support information?

What version of StorNext will be installed?

What is the maximum number of directories expected (in millions)?

What is the maximum number of files expected (in millions)?

How many copies will be stored for each file?

How many versions will be retained for each file?

Note: Keep in mind that storage needs typically grow rapidly. Consider increasing the maximum number of expected directories and files by a factor of 2.5x to ensure room for future growth.

Note: The pre-installation script ignores unmounted file systems. Before running snPreInstall, be sure to mount all local file systems that will hold StorNext support information.

To run the pre-installation script, use the StorNext installation CD.

1Log on to the MDC as root.

2Mount the StorNext installation CD and change to the CD root directory.

3List the installation directories on the CD. At the command prompt, type: ls -l

4Identify the correct installation directory for your operating system and hardware platform, and then change to that directory.
