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.
I have mounted an ISO-file to do a network install of Red Hat. Afterwards, I removed the ISO and forgot about the mount.
Now, I am unable to unmount this mount, because the target no longer exists...

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'.
NOTE: I think in RHEL3 we cannot unmount with device name. Correct me if I am wrong.

autounmountd
AUTOUNMOUNTD(8) BSD System Manager's Manual AUTOUNMOUNTD(8)NAME
autounmountd -- daemon unmounting automounted filesystems
SYNOPSIS
autounmountd [-d] [-r time] [-t time] [-v]
DESCRIPTION
The autounmountd daemon is responsible for unmounting filesystems mounted by automountd(8). On startup, autounmountd retrieves a list of
filesystems that have the automounted mount option set. The list is updated every time a filesystem is mounted or unmounted. After a speci-
fied time passes, autounmountd attempts to unmount a filesystem, retrying after some time if necessary.
These options are available:
-d Debug mode: increase verbosity and do not daemonize.
-r Number of seconds to wait before trying to unmount an expired filesystem after a previous attempt failed, possibly due to filesystem
being busy. The default value is 600, or ten minutes.
-t Number of seconds to wait before trying to unmount a filesystem. The default value is 600, or ten minutes.
-v Increase verbosity.
EXIT STATUS
The autounmountd utility exits 0 on success, and >0 if an error occurs.
SEE ALSO auto_master(5), autofs(5), automount(8), automountd(8)HISTORY
The autounmountd daemon appeared in FreeBSD 10.1.
AUTHORS
The autounmountd was developed by Edward Tomasz Napierala <trasz@FreeBSD.org> under sponsorship from the FreeBSD Foundation.
