Upgrading to StorNext 3.5.1 (SNFS and SNSM) 7
The pre-installation script bases directory location recommendations on the
following criteria:
• To aid disaster recovery, the Database and Journal directories should be

• 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 3.5.1 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.
1 Log on to the MDC as root.
2 Mount the StorNext installation CD and change to the CD root directory.
3 List the installation directories on the CD. At the command prompt, type:
ls -l
4 Identify the correct installation directory for your operating system and
hardware platform, and then change to that directory.
For example, for Red Hat Linux 5 running on an x86 64-bit platform, change
to the
RedHat50AS_26x86_64 directory.
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

(SNFS Only).
Note: When you mount a CD in a Red Hat 4 or 5 system, CDs are
mounted by default with a noexec (non-executable) option
which prevents you from proceeding with the installation.
For Red Hat users only, before proceeding you must
remount the CD by typing mount -o remount, exec ...
