First of all, check compatibility solution matrix to see if it is supported online resizing of one LUN with your specific storage and operating system .
(I had problems in the past with a 3PAR which didn't support online resizing with HPUX)
Once LUN resized, kernel must see new disk size check it with:
If not, try to scan and run diskinfo again.
If no results, try to reboot the server.
If there is no onlineJFS you could see the new disk size but always will need umount that filesystem to extend it.

Hi,
I know that if we need to unmount a device, we use the command umount mount-point, example 'umount /tmp/mount1'
But We can also unmount the device with device name example 'umount /dev/hda6'.

umount.nfs
UMOUNT.NFS(8) System Manager's Manual UMOUNT.NFS(8)NAME
umount.nfs, umount.nfs4 - unmount a Network File System
SYNOPSIS
umount.nfs dir [-fvnrlh ]
DESCRIPTION
umount.nfs and umount.nfs4 are a part of nfs(5) utilities package, which provides NFS client functionality.
umount.nfs4 and umount.nfs are meant to be used by the umount(8) command for unmounting NFS shares. This subcommand, however, can also be
used as a standalone command with limited functionality.
dir is the directory on which the file system is mounted.
OPTIONS -f Force unmount the file system in case of unreachable NFS system.
-v Be verbose.
-n Do not update /etc/mtab. By default, an entry is created in /etc/mtab for every mounted file system. Use this option to skip delet-
ing an entry.
-r In case unmounting fails, try to mount read-only.
-l Lazy unmount. Detach the file system from the file system hierarchy now, and cleanup all references to the file system as soon as it
is not busy anymore.
-h Print help message.
NOTE
For further information please refer nfs(5) and umount(8) manual pages.
