Re: not able to unmount file system
>>Disk is missing
How do you come to know about this?
Whats the o/p of umount command?
Can you post :
# vgdisplay -v vg_name
# ioscan -fnC disk
# diskinfo /dev/rdsk/c#t#d#
Regds,
R.K.

Re: not able to unmount file system
Did you check your /var/adm/syslog/syslog.log ?
Is there any error there ?
check with this below commands
fuser -cu /your_file_system
fuser -ku /your_file_system
then try to unmount the FS

Re: not able to unmount file system
I can see NO_HW output in ioscan and PV status unavailable while running vgdisplay -v vgdata_fc03. I know that lun has been removed becasue it was to be moved but storage guys didnt bothered to ask us and they removed it without deactivating the VG.
Thanks
Madan.

Re: not able to unmount file system
if the system is possible to reboot, them uncomment the mounted volume in /etc/fstab and reboot the server.

Re: not able to unmount file system
Then a reboot is your *only* option.
You have IO calls that are never going to return... in this situation you cannot ever umount or get rid of the processes and any process that wants to sync filesystems (like bdf) will also hang.
Systems don't react well to having storage ripped out from underneathy them whilst their still using it - this is pretty much the case for any OS, not just HP-UX.
I'd be having some *very* strong words with my storage team abount change control and change management...

Re: not able to unmount file system
Then you need a reboot my friend.
but before reboot move your /etc/lvmtab and do a vgscan -v.
