Hi,

1. Open dvd drive
2. Insert a dvd
3. Close dvd drive
4. Mount dvd drive

When you put the dvd into the drive it should flash green (as it reads the dvd) and then display no light once the dvd is loaded.

As others have indicated before try the following:(samples are from one of my old pa-risc servers.)
root@serverx:/root> ioscan -funC disk
Class I H/W Path Driver S/W State H/W Type Description
==========================================================================
disk 0 0/0/3/0.0.0.0 sdisk CLAIMED DEVICE TEAC DV-28E-N
/dev/dsk/c0t0d0 /dev/rdsk/c0t0d0
disk 1 0/1/1/0.1.0 sdisk CLAIMED DEVICE HP 73.4GST373454LC
/dev/dsk/c2t1d0 /dev/rdsk/c2t1d0
disk 2 0/1/1/1.0.0 sdisk CLAIMED DEVICE HP 73.4GST373454LC
/dev/dsk/c3t0d0 /dev/rdsk/c3t0d0
root@serverx:/root> diskinfo /dev/rdsk/c0t0d0
SCSI describe of /dev/rdsk/c0t0d0:
vendor: TEAC
product id: DV-28E-N
type: CD-ROM
size: 0 Kbytes
bytes per sector: 0

When size = 0 kbytes it usually indicates there is no cd in drive. When one is successfully loaded:
root@serverx:/> diskinfo /dev/rdsk/c0t0d0
SCSI describe of /dev/rdsk/c0t0d0:
vendor: TEAC
product id: DV-28E-N
type: CD-ROM
size: 4090998 Kbytes
bytes per sector: 2048

If you input diskinfo -v /dev/rdsk/c0t0d0 it will display firmware version as well as other information.
If the dvd is bootable try:
root@serverx:/> mount -r /dev/dsk/c0t0d0 /cdrom
root@serverx:/> cd /cdrom
root@serverx:/cdrom>

You could also try:
mount -F cdfs /dev/dsk/c0t0d0 /cdrom
If still no go what is output of fuser (dvd directory)
strings /etc/lvmtab
cat /etc/fstab
ll /dvddirectory for owner:group permissions
example: drwxr-xr-x 2 root sys 96 Jan 3 2007 cdrom

Lastly are there any other hp-ux based servers you could try to duplicate your attempts with?

Lawrence,

Why don't u try or check out the following :-
Do a diskinfo on the specified device file and see if it is a DVD-ROM as well as check if the size of the disk is being shown to make sure that the drive is actually detecting ur disk.

Next thing is have you created the mount point?

Also do a diskinfo on /dev/rdsk/c0t0d0 cez typically that is the drive you would be concerned with.

If not, try mounting the DVD with persistent DSF if u r using v3 by doing an ioscan -m dsf.

Best of luck,
