VERITAS 4.1 Installation Guide (March 2006)

Setting Up Base-VXFS 4.1 and Base-VXVM 4.1
Chapter 534
/opt/VRTS/vxfs4.1/man directory is automatically added to the
/etc/MANPATH. Make sure that /opt/VRTS/vxfs4.1/man appears before
/usr/share/man in your MANPATH environment variable to display the latest
version of the Base-VXFS 4.1 manpages.
Upgrading the Base-VXFS Disk Layout
Base-VXFS 4.1 enables you to mount the following file system disk layouts:
• Disk Layout Version 4
• Disk Layout Version 5
• Disk Layout Version 6
The default layout for Base-VXFS 4.1 is Disk Layout Version 6. Any new file system created
using the VxFS 4.1 mkfs command has Disk Layout Version 6, unless explicitly specified.
To specify Version 4 or Version 5 disk layout, run the following command:
# mkfs -F vxfs -o (version=4|version=5) <special>
To determine the file system layout, run the following command:
# fstyp -v <special>
The -v option is used for verbose output. The output contains information about the file
system superblock.
