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 4.
