Chapter 9: Configure PSFS Filesystems 116
8.3 Short File Names and Name Tunneling
By default, PSFS filesystems do not support the creation of 8.3 short file
names (SFN) and name tunneling; however, support for these features
can be enabled on specific filesystems. These features should be enabled
only if you have a specific need for them, as the use of 8.3 files causes
degradation in filesystem performance. The degradation is proportional
to the number of 8.3 files created. If 8.3 SFN support is later disabled but
8.3 filenames exist, the performance degradation will continue.
Use the following psfscheck command to enable these features on a
specific PSFS filesystem. Before running the command, be sure that the
volume is not in use.
psfscheck -e enable8dot3 <device>
In the command, device can be specified in several ways:
• By the drive letter, such as X:
• By the mount point (junction), such as C:\san\vol2
• By the psd or psv name, such as psd2p2 or psv1
