umount cdrom problems

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

Re: umount cdrom problems

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.

Re: umount cdrom problems

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

Re: umount cdrom problems

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

Re: umount cdrom problems

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.
