CDROM hangs after manual eject

[Robert Taylor_1]

Hi!

On a variety of systems running HPUX B.11.00, I have had this problem with standard CDROM drives and DVD drives - After using the drive for installs etc. I issue the "umount /cdrom" command. When I go to the drive and try and eject the tray, it does nothing. If I manually eject the tray using the old "paper clip in the hole" trick, sometimes (more often than not), the machine goes into some strange state, where it appears some process is consuming all the CPU for short bursts of time.

Anyone had this problem, and know of a solution??

Thanx in advance

Cheers
Robert

I've only seen this happen with oracle CD's that weren't mounted using the pfs mount command and all of the options.

However, this could also be a firmware or cable thing. I've not heard of dodgy firmware in CDROM's / DVD's but you never know.

Not very helpful I know...

Hi Robert:

One thought that comes to mind is to make sure that your current directory isn't the CD's mountpoint and/or that there are no user's of it:

# fuser -cu /cdrom_mountpoint

Thanks to Scott, who prompted me to check out the PFS thing.

These are in fact Oracle installation CD's.

What I found was that, after killing all the PFS daemons which were running, my problem "went away" (my favourite kind of problem, that!), and I was able to mount the next CDROM the normal (ie. non-PFS) way...

Thanks for your replies

Hi Robert,
An extra thought ...
I would not try to restart the pfs daemons later on on this machine. It's a classical case. Yes, you solved the immediate problem, but since you did not "follow the rules" a next pfs-mount will again cause trouble. Do a reboot of the machine first ...

Just my ???0.02
