StorNext 3.5.1 Upgrade Guide
Document 6-01620-10 Rev A
June 2009
Introduction 0
This document provides information about upgrading to StorNext 3.5.1 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.
Note: Quantum supports upgrades only from the previous two
major releases of StorNext. For example, you can upgrade to
StorNext 3.5.1 from version 3.1 or 3.0, but not from version 2.8
or earlier.
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 4
• Upgrading to StorNext 3.5.1 (SNFS and SNSM) on page 7
• Upgrading to StorNext 3.5.1 (SNFS Only) on page 8
• Contacting Quantum on page 17
Getting Ready to Upgrade 0
This section includes important information about upgrading to StorNext 3.5.1.
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:
• 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.
• Before upgrading, Quantum recommends reviewing system configuration
settings and performing a backup procedure to back up StorNext
configuration files.

StorNext 3.5.1 Upgrade Guide
Document 6-01620-10 Rev A

• 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 changed starting 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
Upgrading HA Systems 0 Upgrades for MDCs running in a High Availability (HA) Failover environment
Upgrading the Client Software
Starting with release 3.0.2, StorNext does not support metadata controllers
running the SGI IRIX operating system. To upgrade to StorNext 3.5.1 from a
0
release earlier than 3.0.2, 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
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 17).
To upgrade to the StorNext 3.5.1 client software on Linux and Unix systems,
install the new client software package. There is no need to uninstall previous
0
versions of the client software. For more information about installing the client
software on Linux and Unix, see the StorNext 3.5.1 Installation Guide.
To upgrade to the StorNext 3.5.1 client software on Windows, follow the
procedure in
Upgrading SNFS on Windows on page 9.
Contacting Quantum on page 17).
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.
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.
Running snPreInstall 0 To run the pre-installation script, use the StorNext installation CD.
1 Log on to the MDC as root.
2 Mount the StorNext installation CD and change to the CD root directory.
3 List the installation directories on the CD. At the command prompt, type:
ls -l
4 Identify the correct installation directory for your operating system and
hardware platform, and then change to that directory.

For example, for Red Hat Linux 5 running on an x86 64-bit platform, change
to the
RedHat50AS_26x86_64 directory.
5 Run the script. At the command prompt, type:
./snPreInstall
The pre-installation script runs (figure 1).

The script outputs results based on the information you entered.
After you enter all requested information, the pre-installation script outputs the
following results:
0
• Estimated disk space required for each support directory.
• Recommended file system location for each support directory.
Tech Tip: For optimal performance, each support directory (other than
the
Backup directory) should be located on its own local file
system, and each local file system should reside on a separate
physical hard disk in the MDC.
There are three types of directory recommendations, as indicated by the text
preceding the recommendation. The three types of recommendations are
described in
Table 2.

RECOMMEND The suggested directory locations will result in
optimal system performance.

Type Description
NOTE The suggested directory locations are valid but
system performance will not be optimal.
SPACE Additional hard disk space is required to store
the required support directories.
The pre-installation script bases directory location recommendations on the
following criteria:
• To aid disaster recovery, the Database and Journal directories should be
located on different file systems.
• For optimal performance, the Metadata directory should not be located on the
same file system as (in order of priority) the
directory.
Note: Do not change the location of support directories manually.
Instead, use the installation script to specify the location for
support directories. For more information, see
StorNext 3.5.1 (SNFS and SNSM) or Upgrading to StorNext 3.5.1
(SNFS Only).

Use the StorNext installation script to upgrade to StorNext 3.5.1 on a metadata
controller running StorNext Storage Manager and StorNext File System. To
launch the script, use the correct StorNext installation CD for your operating
system.
1 Log on to the MDC as root.
2 Mount the StorNext installation CD and change to the CD root directory.
Note: When you mount a CD in a Red Hat 4 or 5 system, CDs are
mounted by default with a noexec (non-executable) option
which prevents you from proceeding with the installation.
For Red Hat users only, before proceeding you must
remount the CD by typing mount -o remount, exec ...
3 List the installation directories on the CD. At the command prompt, type:

backup after the next reboot. These backups trigger a metadata
dump that (depending on the number of files and the type of
hardware) can cause backups to take several hours.
