Before You Begin

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 4.

Support Directory	Description
Database	Records information about where and how
/adic/database	data files are stored.
Journal	Records changes made to the database.
/adic/database_jnl
Mapping	Contains index information that enables quick
/adic/mapping_dir	searches on the file system.
Metadata	Stores metadata dumps (backups of file
/adic/database_meta	metadata).
Backup	Contains configuration files and support data
/backup	required for disaster recovery.

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?

•Which version of StorNext will be installed?
