Dear Manuales,

1.identify the device name of the CDrom from ioscan -fnC disk

2. mount the CDrom using

#mount /dev/dsk/c3t3d0 /mnt

3. Now the CDROM is mounted on /mnt directoty and you access it like any ather filesystem.

You can check if the CDROM is mounted using
#mount command.

With Regards,
Siva.

Hi Manuales

which is your cd device file?

You can find it using ioscan cmd

ioscan -fnkC disk

Class I H/W Path Driver S/W State H/W Type Description
=========================================================================
disk 0 0/0/2/0.0.0.0 sdisk CLAIMED DEVICE TEAC DV-28E-C
/dev/dsk/c0t0d0 /dev/rdsk/c0t0d0
disk 1 0/1/1/0.0.0 sdisk CLAIMED DEVICE HP 36.4GMAS3367NC
/dev/dsk/c2t0d0 /dev/rdsk/c2t0d0
disk 2 0/1/1/0.1.0 sdisk CLAIMED DEVICE HP 36.4GMAS3367NC
/dev/dsk/c2t1d0 /dev/rdsk/c2t1d0

Is the first in my machine "TEAC DV-28E-C" and device is c0t0d0

exec mount command

mount -r -F cdfs /dev/dsk/c0t0d0 /cdrom

cd /cdrom to view file/dir on cdrom

Regards,

Note also, if it is an Oracle cd, or one that wants pfs - do the following:

It can be an Oracle CD-ROM, or a CD created on Windows, or whereever they used Rock Ridge extensions. Long names are truncated or show upper case only. Oracle tells you to use pfs_mount.

Do not use pfs_mount!. Install the Rock-Ridge extension patches instead and never worry about these problems. For HP-UX 11.00 you will need forget all about PFS and install PHKL_26448 (now superceded by PHKL_28060), PHCO_26449, and PHKL_26450 to have HP-UX recognize those file systems automatically on mount! For HP-UX 11.11 (11i) you need PHCO_25841, PHKL_26269, and PHKL_25760 (now superceded by PHKL_28025).

Installation of patches requires a reboot.

To mount a Rockridge CD (instead of using pfs_mount):

mount -F cdfs -o ro,rr,noauto /dev/cdrom /cdrom

To unmount:

umount /cdrom

To share out the cd over NFS:

exportfs -i -o ro,anon=0 /cdrom

On remote:

mount -F nfs sha1:/cdrom /zmnt

Note: client server does NOT need to have Rock Ridge patches installed to access the cdrom remotely.

Rgds...Geoff

Hi Manuales ,

1. Confirm the CD-ROM device file from ioscan -fnC disk output.

2. mount /dev/dsk/devicefile /mnt

3. cd /mnt

4. ls -l

Does this works for you.

hth,
Raj.

Hi,

The mount options will also defer depending upon the type of format in which the CD-media is written.

man pfs_mount from deails.

HTH,
Devender
