StorNext 3.5.1 Upgrade Guide

Running the Pre-Installation Script 4
• 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
0
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
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
Contacting Quantum on page 17).
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 17).
Upgrading the Client
Software
0
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
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.
Running the Pre-Installation Script 0
The StorNext pre-installation script (snPreInstall) is included on the StorNext
installation CD. When you run
snPreInstall, you are prompted for information
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
Backup
directory, which is stored on the managed file system.
The StorNext support directories are described in Table 1.
