1Installing StorNext File System and Storage Manager

This chapter describes how to install StorNext File System (SNFS) and StorNext Storage Manager (SNSM) on a metadata controller (MDC). Install both SNFS and SNSM for storage systems that require policy- based data movement (for example, systems that include tape drives or libraries).

To ensure successful operation, do the following tasks before installing StorNext:

•Make sure the MDC meets all operating system and hardware requirements (see Storage Manager System Requirements).

•Make sure all storage devices are correctly configured and are visible to the MDC (see Getting Ready to Install on page 5)

•(Optional) Run the pre-installation script to check for available disk space and view recommended locations for support directories (see Pre-Installation Script on page 8).

When you are ready to install StorNext File System and Storage Manager on the MDC, run the installation script (see StorNext Installation Script on page 12).

Note: To install only StorNext File System (without Storage Manager), see Chapter 2, “Installing StorNext File System.” To install the StorNext client software, see Chapter 3, “Installing the StorNext Client.”
