Extend a AIX LVM Volume

Today I had a customer who asked me to extend a database volume (if possible). The customer couldn't tell me if there is space available for extending the volume. So I had to check by my self again. After logging into the customers machine the first I ran was df to get the current size and usage of the volume:

# df -k /oradata
Filesystem    1024-blocks      Free %Used    Iused %Iused Mounted on
/dev/oravol01    47185920   5880024   88%       50     1% /oradata

# fstyp -v /dev/vx/dsk/testdg/testvol
vxfs
