Problem in mount cd and dvd

[Nedved]

Dear all,

I am trying to mount one dvd on my Hp-UX B.11.11 rp3410 server. But the following error occured while mounting.


server@root# ioscan -FunC disk
scsi:wsio:T:T:F:31:188:0:disk:sdisk:0/0/2/0.0.0.0:5 128 2 50 0 0 0 0 7 40 158 19 0 0 0 0 :0:root.sba.lba.side_ba.side.tgt.sdisk:sdisk:CLAIMED:DEVICE:_NEC DVD+-RW ND-6650A:0
/dev/dsk/c0t0d0 /dev/rdsk/c0t0d0

server@root#mount /dev/dsk/c0t0d0 /cdrom
mount: /dev/dsk/c0t0d0 on /cdrom : Device busy
server@root#
server@root#fuser -ku /dev/dsk/c0t0d0
/dev/dsk/c0t0d0:

server@root#


Can some one help me how to solve this problem.

its probably some other process already lock the cdrom. Check from bdf if the cdrom already mounted. Look for SDROM mount points as well.

[Jeeshan]

do you have any SAN storage in this box?

which storage? EMC or HP?

This is my bdf output.

Any reason you didn't use fuser on /cdrom? Are you in that directory?
Sometimes you get that "Device busy" if the CD format isn't something that HP-UX will recognize.

Hi,

can you reboot your server?
That's the simpliest ...

Can you open/close the dvd tray?

Hello,

You can try
lsof /dev/dsk/c0t0d0
lsof /cdrom
If no process is present, it try this:

#rmsf -H 0/0/2/0.0.0.0
#ioscan -fn
#insf -eC disk
#mount /dev/dsk/c0t0d0 /cdrom

Hi,
It's better you can remove the /cdrom dir and then create a same and mount.
