Hi,

Execute the following

# lssf /dev/dsk/c6t2d0

What do you see any errors? Execute the following to re-install the special files.

# insf -e

Hope this helps. Regards.

Try mounting this with these steps.
mkdir /cdrom
mount -F cdfs /dev/dsk/cXtYdZ /cdrom

There must be a CD inserted in the device for this to work properly.

Good Luck.

If you try to mount certain types of CDROMs (there are several dozen different ways the 'standards. for CDROM filesystems can be used and the HP-UX cdfs code has not had a major rewrite for more than 10 years.

As mentioned, you may have to tell the mount command -F cdfs, and if that does not work, add the -r option as in:

mount -F cdfs -r /dev/dsk/c6t2d0 /cdrom

Note there may be format issues with the filenames, so add -o cdcase and see if that helps. HP-UX cannot read pure Joliet filesystems (common with PC CDROMs) and requires a helper set of programs to read RockRidge extensions or ECMA 168 CDs.

Hi,

Do a diskinfo on /dev/rdsk/c6t2d0 and see if it returns the type CD-ROM.

lssf /dev/dsk/c6t2d0 will give you the path and you can find if it is really a CD-ROM drive.

Also make sure you have a CD in there. Otherwise you will get no such device addresss.
