Hi,

do a

chfs -a size=+100M /u01

if you want to extend your filesystem by 100MB - the underlying logical volume will be resized accordingly. If this fails - i.e. because your logical volume had been created only to allow i.e. 512 pp's you can change this using smitty lv - change logical volume by just amending the number.
All this assumes that you have free space in your volumegroup.

Kind regards
