umount cdrom problems

Lars Karlsson — Tue, 15 Jan 2002 12:37:11 GMT

Hi all, I'm new in this forum and aswell a newbie in HP UX . The other day I installed a "patch package" on our hp box and after that I have had some small issus.
One of them is that I can't mount or unmount the cdrom on it. I have tried umount /cdrom that does not work , I have also tried to do pfs_umount /cdrom - gives an error saying block device required.
Another thing is that if I run bdf i can't see that there is any cdrom mounted at all , but if I do cd /cdrom i dont get any error I can then do pwd and it shows /cdrom if then do a ls it does find anything (there is a cd in the cdrom).
My hp ux is not that big so I would appreciate all help I can get.

Many thanks
Lars. K.

Hi Lars,

The cd may not be mounted on /cdrom. Use "ioscan -fnkC disk" to identify the device name for your cdrom drive. Then use bdf (or mount) to see where that device is mounted. Then use "fuser -c /xxxx" where /xxxx is the mount point of the cdrom. If any processes are listed then the cdrom is in use and can't be umounted. If no processes are listed, then umount /xxxx.

I remember, may be your CD isn't mount yet, but you aren't able to open the tray.
If it is so, you have to mount following umount your CD.
mount /dev/dsk/cxtydz
umount /dev/dsk/cxtydz
/dev/dsk/cxtydz is your appropriate device file.

Hope this helps

This means your CD isn't mounted yet.
Where is your problem?

Well if I try to mount the cdrom it doesn't work

if i run
mount -o cdcase /dev/dsk/c1t2d0 /cdrom

it just sits there waiting for something ...nothing happens...

I've tried psf_mount aswell nothing happens ..

I think someting is really became screwed up after I applied the patch patch package. It worked before I installed it.

Hi again,

Try:
mount -F cdfs -o cdcase /dev/dsk/c1t2d0 /cdrom

From the output of the ioscan and bdf it seems that you never really mounted the CDROM. Check if you can open the tray. If yes then it is not mounted.

to mount a cd simply type

mount -r /dev/dsk/c1t2d0 /cdrom. Be sure though that the directory cdrom EXISTS in the root directory.

simply do an ls / and see if a directroy cdrom exists.
if not type mkdir /cdrom.

to unmount type umount /cdrom.

good luck stefan

Hi Lars,

where do you wait for if you say:
"Well if I try to mount the cdrom it doesn't work".
Are you back in the prompt after mount command without output? Then your command was succesful.
Or do you get any error message?

Hi,

If you want to mount a cdrom follwo these steps.

if you dont't have a cdrom directory create it by

mkdir /cdrom

Then follow these steps:
Follow these steps sequentially to mount a oracle cd

# nohup /usr/sbin/pfs_mountd &
# nohup /usr/sbin/pfsd &

/usr/sbin/pfs_mount -t rrip -x unix /dev/dsk/c1t2d0 /cdrom

For other CD's
mount -F cdfs -r -o cdcase /dev/dsk/c1t2d0 /cdrom

Goodluck,
-USA..
