• 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.

 

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).

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,

Software

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

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.
