My system is HP Itanium unix (B.11.23 U ia64).
I tried to increase /opt size in single user mode using
lvextend -L size_number /dev/vg00/lvolx

However, it can't be reflected when I execute "bdf" command
while it can be only reflected under SAM.

If I use the following command, it works in both SAM and "bdf"
extendfs /dev/vg00/lvolx

Would you please advise whether "extendfs" is necessary to make
the change effective. Thanks!

Extending the logical volume extends the container but does
not extend the filesytem within that container.

Correct.  Layers of the onion.  Logical volume and filesystem
are at different layers.  A logical volume is a container for
a filesystem.  A filesystem is a container for files.  An
inode is a container for blocks. A file is a container for
data.
