mount cdrom problem

ANDRE David — Thu, 24 Jul 2003 07:53:58 GMT

hi,

i try to mount a cdrom on HpUX 11.11 with this command :

$mount -o ro /dev/dsk/c3t2d0 /cdrom
the cdrom is mounted but the file is not correct

ll /cdrom

Readme.html;1
...

All files have ";1" at the end
Which option can i use to have a good file? ( Readme.html )

If i use cdcase, there isn't ";1" but all files are lowercase. ( it's not good... )

Thanks.

hi,
you could try with pfs_mount, but it can cause a reboot when care is not taken.

If you wish, latest mount patches allow you to mounf pfs without the need for special demons.

PHKL_28025

It requires a reboot.

extract from notes:

PHKL_26520:
( SR:8606244607 CR:JAGae11092 )
PHKL_25760 introduced behavior that can result in problems
accessing files from mounted CDFS file systems, for example
CD and DVD media. The cdfs driver included in PHKL_25760
may show and match all file names as lower case characters.

Are you mounting CD from Oracle?
If yes, for hpux, you should follow the mounting instructions:

# nohup /usr/sbin/pfs_mounts &
# nohup /usr/sbin/pfsd &
# /usr/sbin/pfs_mount -t rrip -x unix /dev/dsk/c5t2d0 /SD_CDROM

if there is no /etc/pfs_fstab, create it as follows:
# cat /etc/pfs_fstab
/dev/dsk/c5t2d0 /SD_CDROM pfs-rrip xlat=unix 0 0

Hope it helps!

Hi,

If it is an Oracle cd it will have to be mounted using pfs_mount.

Also don't forget to unmount using pfs_umount

Hi,

option cdcase will eliminate ";1" and shows all files with lowercase - not good?
You can try RockRidge. But for the option rr you will need patches (HP UX 11):

PHKL_28060
PHKL_26450
PHCO_26449

I don't know if you cdrom is RockRidge-formatted. But there are no more possibilities

I had a thread with cdrom burning and reading:

Good luck

Hi again,

look here ("New patches will eliminate pfs_mount for CD-ROMs"):
http://www4.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000067424041

My patches were for 11.0, there you can find the same for 11.i

PHCO_25841
PHKL_26269
PHKL_28025

because pfs_mount could cause problems.

Volkmar

PFS is essentially obsolete due to problems and the recently added patches for RockRidge formats. After adding the above patches for your 11.11 system, use the -orr option to mount your CD. The UPPERCASE.EXT;1 format is standard ISO-9660 format for files. But the CDROM standard (aka, the Yellow book) defines additional directories that are used to translate the 8.3;version format into long filenames, etc. These 3 patches will now access the additional directories on the CD and display the desired filenames. NOTE: HP-supplied CDs (for HP-UX) are written in a proprietary (non-standard) format which is understood by the native CDFS code in HP-UX.

Hi,

The reason is the file type on the CD is not of UNIX.

When you user pfs_mount with the option -x unix it will translate to file type UNIX.

To user pfs_mount, you need the pfs_mountd and pfs running.

The do the following

# nohup /usr/sbin/pfs_mounts &
# nohup /usr/sbin/pfsd &
# /usr/sbin/pfs_mount -x unix /dev/dsk/c5t2d0 /cdrom

This will work.

I think that you meant

nohup pfs_mountd& instead of nohup pfs_mounts&

also do not forget the
/etc/pfs_fstab has to be built

example:

/dev/dsk/c3t2d0 /SD_CDROM pfs-rrip xlat=unix 0

Your device and mount point will vary, but the rest of the line will be the same.

Hello!

Try like this:
mount -o cdcase /dev/dsk/c3t2d0 /cdrom

hi,

i prefer to use my script which allows me to both mount and unmount my Oracle cds.

It uses pfs_mount.

hope this helps!
