Introduction 0
This document provides information about upgrading to StorNext 3.0 from a
previous version. Instructions are provided for metadata controllers (MDCs)
running both StorNext File System (SNFS) and StorNext Storage Manager
(SNSM), as well as for MDCs running SNFS only.
For upgrade procedures, or to learn how to contact Quantum for assistance, see
the following sections:
• Getting Ready to Upgrade on page 3
• Running the Pre-Installation Script on page 5
• Upgrading to StorNext 3.0 (SNFS and SNSM) on page 7
• Upgrading to StorNext 3.0 (SNFS Only) on page 8

Getting Ready to Upgrade 0
This section includes important information about upgrading to StorNext 3.0.
Review the following sections before upgrading:
• Upgrade Guidelines
• Converting a Metadata Controller Running IRIX
• Upgrading HA Systems
• Upgrading the Client Software
Upgrade Guidelines 0
Before upgrading StorNext, review the following upgrade guidelines:
• The trashcan feature has been removed in StorNext 3.0. Before upgrading to
StorNext 3.0, you must empty the trashcan on all file systems where this
feature is enabled. If the trashcan directories are not removed, the upgrade
will fail.
To empty the trashcan on a file system where it is enabled, change to the file
system directory (for example
prompt, type:
rm -rf TrashCan
Repeat this procedure for all file systems.
/stornext/snfs1). Then, at the command
• Before upgrading, make sure there is no I/O activity. On the StorNext home
page, the number of store candidates should be 0. For tape drives, make sure
no media is mounted and no read/write operations are being performed. If
there is I/O activity, wait for the I/O activity to complete before upgrading. If
you attempt to perform an upgrade during a period of high activity, the
upgrade may fail.

StorNext 3.0 Upgrade Guide

• Before upgrading, Quantum recommends reviewing system configuration
settings and performing a backup procedure to back up StorNext
configuration files.
• Before upgrading, Quantum recommends storing all files. (If you do not store
files prior to upgrading, Quantum recommends running a rebuild policy after
the upgrade.)
• Before upgrading, Quantum recommends making sure all tape drives are at
approved firmware levels. After upgrading, you may not be able to use
drives that are not running an approved firmware version.
• Because the metadata dump format has changed in StorNext 3.0, a metadata
dump is automatically performed during the upgrade process. Depending on
the size of the file system, this can extend the time required to complete the
upgrade.
• After upgrading, your StorNext license remains valid. You do not need to
request a new licence if the system ID does not change.
Converting a Metadata Controller Running IRIX 0
StorNext 3.0 does not support metadata controllers running the SGI IRIX
operating system. To upgrade to StorNext 3.0, MDCs running IRIX must be
converted to a supported operating system. This conversion must be performed
by Quantum Professional Services. For more information, or to schedule an IRIX
conversion, contact the Quantum Technical Assistance Center (see
Contacting
Quantum on page 16).
Note: The StorNext 3.0 client software continues to support IRIX.
Upgrading HA Systems 0
Upgrades for MDCs running in a High Availability (HA) Failover environment
must be performed by Quantum Professional Services. If your system is running
with failover enabled, contact the Quantum Technical Assistance Center (see
Contacting Quantum on page 16).
Upgrading the Client Software 0
To upgrade to the StorNext 3.0 client software on Linux and Unix systems, install
the new client software package. There is no need to uninstall previous versions
of the client software. For more information about installing the client software on
Linux and Unix, see the StorNext 3.0 Installation Guide.
To upgrade to the StorNext 3.0 client software on Windows, follow the procedure
in
Upgrading SNFS on Windows on page 9.

Running the Pre-Installation Script 0
The StorNext pre-installation script (snPreInstall) is included on the StorNext
installation CD. When you run
about your system. The pre-installation script uses this information to estimate
the amount of local disk space required for SNFS and SNSM support directories.
In addition, the script recommends the optimal locations for support directories.
StorNext uses five directories to store application support information. These
directories are stored locally on the metadata controller, except for the
directory, which is stored on the managed file system.
The StorNext support directories are described in Table 1.

Contains configuration files and support data
required for disaster recovery.
Before You Begin 0 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.
