Re: unable to mount DVDrom on HPUX

Do you see the DVD in the 'ioscan -fn -C disk' listing?

Can you try this: # mount -o rr /dev/dsk/c0t0d0 /cdrom

Re: unable to mount DVDrom on HPUX

Hi,

Firstly, try checking if OS identfies the FS on the CD.

# fstyp /dev/dsk/c0t0d0

If the OS is able to recognize the OS type, you could use the output with "-F" option in "mount" command.

If unable to mount with "-F" specified inspite of OS recognizing the FS type in fstyp command, the chances are that the Media could be bad. If fstyp displays unrecognised FS, then you are out of luck.

Try with following options, just in case

mount -o cdcase /dev/dsk/c0t0d0 /cdrom
or
mount -o rr /dev/dsk/c0t0d0 /cdrom
or
mount -o norr /dev/dsk/c0t0d0 /cdrom

For more details,
man mount_cdfs

Let your effort be such, the very words to define it, by a layman - would sound like a "POETRY" ;)

Hi ,

before need do some checking.

bdf
fuser -c /cdrom
pwd

step 1:- ioscan -fnC disk
<

Example :-
========
# ioscan -fnC disk
Class I H/W Path Driver S/W State H/W Type Description
====================================================================================
disk 0 0/0/2/1.0.16.0.0 sdisk CLAIMED DEVICE TEAC DV-28E-N
/dev/dsk/c0t0d0 /dev/rdsk/c0t0d0


step 2:- mkdir /DVD

step 3:- mount -D cfs

step 4:- insf -e

step 5 :- mount -F cdfs /dev/dsk/c0t0d0 /cdrom

Thanks,
Johnson

Re: unable to mount DVDrom on HPUX

senthil,
looks no luck, fstype gives unknown type,

# fstyp /dev/dsk/c0t0d0

unknown_fstyp (no matches)

what else could be done to make that fs up on dvdrom.
