3.6.1 HP PolyServe Matrix Server Administration Guide (T5392-96018, August 2008)

Chapter 9: Configure PSFS Filesystems 117
When 8.3 support is enabled, applications requiring 8.3 short file names
and name tunneling will work correctly. Filesystems enabled for 8.3
support cannot be mounted on Matrix Server versions earlier than 3.6.1,
even if the 8.3 support is later disabled.
8.3 support can be disabled on a filesystem by using the following
command. Before running the command, be sure that the volume is not in
use.
psfscheck -e disable8dot3 <device>
When 8.3 support is disabled, 8.3 file names will no longer be created and
the name tunnel cache will be purged and removed.
Using the Extended Character Set
Using the extended character set in 8.3 file names can be allowed or
disallowed cluster-wide. (By default, it is disallowed.) Use the following
commands to allow or disallow the use of the extended character set.
Before running the commands, be sure that the volume is not in use.
psfscheck -e allowextchar
psfscheck -e disallowextchar
You can combine options in a single command. For example, you can
specify both 8.3 support and the extended character set:
psfscheck -e enable8dot3 -e allowextchar <device>
Determine Status of 8.3 SFN on a Filesystem
The are several ways to determine whether 8.3 SFN is supported on a
particular filesystem. The Features tab on the filesystem’s Properties
window (select the filesystem, right-click, and select Properties) lists all
supported features. For an example, see “Features Tab” on page 120.
The psfsinfo command specifies whether 8.3 support and the extended
character set are enabled on the filesystem. (1 means the feature is
enabled and 0 means the feature is disabled.) For example:
psfsinfo psv1
Version: 11
BlkSize: 8192
FsSize: 52428792
