Upgrading to StorNext 3.0 (SNFS and SNSM) 7
There are three types of directory recommendations, as indicated by the text
preceding the recommendation. The three types of recommendations are
described in Table 2.
Table 2 Pre-Installation Script
Recommendation Types
The pre-installation script bases directory location recommendations on the
following criteria:
• To aid disaster recovery, the Database and Journal directories should be
located on different file systems.
• For optimal performance, the Metadata directory should not be located on the
same file system as (in order of priority) the Journal, Database, or Mapping
directory.

Use the StorNext installation script to upgrade to StorNext 3.0 on a metadata
controller running StorNext Storage Manager and StorNext File System. To
launch the script, use the correct StorNext installation CD for your operating
system.
1Log on to the MDC as root.
2Mount the StorNext installation CD and change to the CD root directory.
3List the installation directories on the CD. At the command prompt, type:
ls -l
Tech Tip: For optimal performance, each support directory (other than
the Backup directory) should be located on its own local file
system, and each local file system should reside on a separate
physical hard disk in the MDC.
Type Description
RECOMMEND The suggested directory locations will result in
optimal system performance.
NOTE The suggested directory locations are valid but
system performance will not be optimal.
SPACE Additional hard disk space is required to store
the required support directories.
Note: Do not change the location of support directories manually.
Instead, use the installation script to specify the location for
support directories. For more information, see Upgrading to
StorNext 3.0 (SNFS and SNSM) or Upgrading to StorNext 3.0
(SNFS Only).
