StorNext 3.1.3 Installation Guide 114
Manually Modifying Storage Manager Configuration
StorNext employs global parameters that define the Storage Manager
configuration. Although the default values in these files are sufficient for
most installations, you can edit the files to customize the StorNext
software for your specific installation. This section provides a procedure
that can be used to modify the following StorNext configuration files:
• /usr/adic/TSM/config/fs_sysparm_override
• /usr/adic/TSM/config/filesize.config
• /usr/adic/TSM/logs/log_params
fs_sysparm_override
Configuration File 2
The fs_sysparm_override configuration file is used to tune items related to
system administration, drives and media, media manager interface, and
other miscellaneous items. For more information about the parameters
that can be placed into the
fs_sysparm_override configuration file, refer to
the
fs_sysparm.README file.
Caution: Incorrect modification of the fs_sysparm_override
configuration file can cause a serious, adverse effect on
StorNext functionality. Before modifying this file,
Quantum recommends that you contact Quantum Global
Services.
Caution: If you have files larger than 100GB and are using LTO2
media, the MED_SEG_OVER_LTO parameter may be
modified to a value less than or equal to 190G to reduce
file fragmentation. This has the adverse effect of reducing
the potential for parallel I/O for multiple file segments.
Setting the MED_SEG_OVER_LTO parameter to a value
larger than 190GB may result in allocation failures that
prevent file movement to tape.
