CD-ROM Mounting Problem

[Mohammed Imran]

Massimo
I didn???t use pfs_mount
Din???t show in bdf

George
Doesn???t show up the cdrom in bdf

SEP
fuser -cu /mnt
No process seen
No process in open in the CD-ROM

Procura
# fuser -cu /dev/dsk/c0t0d0 (below is the output)
Could not find file system mounted at /dev/dsk/c0t0d0

Caesar
Tried diskinfo /dev/rdsk/c0t0d0 (and got the following output)
SCSI describe of dev/rdsk/c0t0d0:
Vendor: LITEON
Product id: CD-ROM LTN485S
Type: CD-ROM
Size: 0
Bytes per sector: 0

B. Selvaraj
No other process is running by ps -ef. .

2. Try whether the /dev/dsk/c0t0d0 is accessible. (diskinfo)
Yes it is
3. Try unmounting the same .
It is not mounted how can I unmount
4. If nothing works, I will go for a reboot :( though it is not a clean solution
Re-booted still the same.

Still waiting all the help.

Hi Mohammed,

http://forums.itrc.hp.com/cm/QuestionAnswer/1,,0x4319c1c1db31724e9b65751bfd05bd45,00.html

above is your previous question.

How about creating a new directory.

# mkdir /cdrom
# mount /dev/dsk/c0t0d0 /cdrom

Robert-Jan.

[George_Dodds]

What model system is this?

It could be a hardware issue with the cdrom,I know it's a pain but do you have a spare you could test with?

[George_Dodds]

Doh it's a B2000 aint it.

Try a new mount point as Robert has suggested.

It's a logshot but have you tried a different cd in the drive as well.

[H.Merijn Brand (procura]

Sorry - cut'n'paste error. the -c is to check for use of a mounted device

# fuser -u /dev/dsk/c0t0d0

and the suggestion of creating a new mountpoint sounds very good to me.

Enjoy, have FUN! H.Merijn

Hi Mohammed,

last option recreate the device files,

take a look at next link.

http://www4.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000069099078

# mv /dev/rdsk/c0t0d0 oldc0t0d0
# mv /dev/dsk/c0t0d0 oldc0t0d0
# insf -e

Hope it helps,

Robert-Jan.

[Mohammed Imran]

Rob,
NO luck same thing:
/dev/dsk/c0t0d0: Device busy.

[George_Dodds]

Does the drive read the cd when you put it in.

ie is the LED flashing when a cd is inserted?

[Mohammed Imran]

Geroge.
Yes please

[H.Merijn Brand (procura]

Does the LED *keep* flashing, or does it dim after a short while?

If it keeps flashing, your drive cannot cope with the CD inserted. Was it a rewritable?

Enjoy, have FUN! H.Merijn

[Mohammed Imran]

Procura,

Does the LED *keep* flashing (NO)
or does it dim after a short while? (YES)

it IS not a rewritable?

This is when you have to start looking at things that really shouldn't have anything to do with it e.g
automount, seriously mucked up fstab, NFS exports, scsi reserve on a CD if that is actually possible. Other people here can tell if these are really not possible but I'd start looking at the weird stuff!

This one is an interesting one but only if it's not a hardware problem :)

[Mohammed Imran]

Mark,
I m sure ther is no hardware problem.
Please give me solution to sort this problem.
thanks
