Upgrade VxFS

First get the current version:

# fstyp -v /dev/vx/dsk/testdg/testvol
vxfs
magic a501fcf5  version 7  ctime Mon Sep 10 03:06:00 2012
...

The above output shows version 7. Next use vxupgrade to upgrade the file system (/dev/vx/dsk/testdg/testvol is mounted on /local):

# vxupgrade -n 8 /local

If you try to upgrade to a higher version that is not implemented then you will get the following error:

# vxupgrade -n 9 /local
UX:vxfs vxupgrade: ERROR: V-3-22569: new_version must be <= 8
