When increasing the size of a logical volume, you also need to extend the size of the filesystem as well.
At a guess, you haven't got online JFS installed, so the increase cannot be done without first unmounting the filesystem.

To check the software
# swlist -l product | grep -i jfs
If it returns only JFS and not Online JFS as well, you cannot extend the filesystem without first unmounting it, whether it is through 'sam' or the command line.

There are two steps to this, first the extension of the logical volume 'lvextend'(/dev/vgxx/mylv) and the second which extends the filesystem 'extendfs'

if you have online jfs then

$ /usr/sbin/swlist -l product | grep -i jfs

you can just do
# lvextend -xxxxL /dev/vgxx/lvol?
# fsadm -F vxfs -b xxxxxx /opt

If you do not have OnlineJFS

then you need to umount the file system and then increase it using

# lvextend -xxxxL /dev/vgxx/lvol?
#extendfs /dev/vgxx/rvol?

Then again mount it.

(assuming that you are extending the non-system file systems )

Thanks

Guru's,

Do you mean that let say I have online JFS I can extend the filesystem (even system filesystem) without umount the filesystem first.

Yes, if Online JFS is installed there are a number of features you can take advantage of:
increasing filesytem sizes
changing parameters, like changing it to largefile option.
There are some filesystems that you can't which are the ones that are contiguous (/, /stand and primary swap /dev/vg00/lvol2) which cannot) These must be done using 'ignite'.

If you find that you can't unmount your filesystem, there will be processes running. These must be terminated first.
If these are part of the OS (/, /stand, /opt, /usr, /tmp, /var) etc, you will need to find another alternative by using ignite, or booting into single user mode.
