[Robert-Jan Goossens]

Hi,

# mkdir /cdrom

# mount /dev/dsk/c0t0d0 /cdrom
or
# mount -F cdfs /dev/dsk/c0t0d0 /cdrom

use
# umount /cdrom
to unmount the cdrom

Regards,
Robert-Jan

Shalom,

disk 0 0/0/3/0.0.0.0 sdisk CLAIMED DEVICE TEAC DV-28E-C

/dev/dsk/c0t0d0 /dev/rdsk/c0t0d0

Definitely it. Interesting brand of drive. This is the standard that came with the system?

If there is media you should be able to mount it using /dev/dsk/c0t0d0

Post error message please.

Well I can see it:

disk 0 0/0/3/0.0.0.0 sdisk CLAIMED DEVICE TEAC DV-28E-C
/dev/dsk/c0t0d0 /dev/rdsk/c0t0d0

Hello,
below is the error i get.

moon2:/#mount /dev/dsk/c0t0d0 /cdrom
mount: cannot access -specific mount command

[Torsten.]

This slime line IDE drive is standard for some server models.

What kind of CD you're trying to mount?

[Musa I. S.]

A DVD. I'm trying to install ignite-ux.

[Dennis Handly]

>#mount /dev/dsk/c0t0d0 /cdrom

Unless you already have an entry in /etc/fstab, you'll need to supply zillions of options to mount.
Why not use SAM to do this and leave an entry in fstab?

[Torsten.]

If this DVD is the install DVD, try

#mount -r /dev/dsk/c0t0d0 /cdrom

[Musa I. S.]

both mount -r and SAM gave me thesame error as before.

[Torsten.]

>> "mount: cannot access -specific mount command"

Are you root?

[Musa I. S.]

yes i am root

[Robert-Jan Goossens]

try these

# mount -F cdfs -o cdcase /dev/dsk/c0t0d0 /cdrom

# mount -o ro /dev/dsk/c0t0d0 /cdrom

[Musa I. S.]

Didn't work. I got the errors below



moon2:/#mount -F cdfs -o cdcase /dev/dsk/c0t0d0 /cdrom
mount: cdfs : Invalid argument
usage: mount [-l][-v|-p]
mount [-F FStype][-eQ] -a

moon2:/#mount -o ro /dev/dsk/c0t0d0 /cdrom
mount: cannot access -specific mount command

[Torsten.]

I think your "mount" is not the command - it's another script.

Try

# whereis mount
# whence mount

and post the results.

Try

/usr/sbin/mount -r /dev/dsk/c0t0d0 /cdrom

instead of only "mount".

[Musa I. S.]

I tried it, and it still didn't work.

moon2:/#whereis mount
mount: /usr/sbin/mount /sbin/mount /opt/VRTS/bin/mount /usr/share/man/man1m.Z/mo
unt.1m /usr/share/man/man2.Z/mount.2 /usr/share/man/man3.Z/mount.3n
moon2:/#whence mount
/usr/sbin/mount

moon2:/#/usr/sbin/mount /dev/dsk/c0t0d0 /cdrom

moon2:/#

>it still didn't work.

Have you tried using SAM?

[Musa I. S.]

SAM gave me the same error

[Anka · Accepted solution]

the problem was due to an error on the cdfs kernel module

check with:
#kcmodule -v cdfs

you may see the following:

"State unused (because of an error)"

If so, loading the cdfs kernel module should corrected the error in the kcmodule output, as well as the issue with mount

[Musa I. S.]

what should i do next?

moon2:/#kcmodule -v cdfs
Module cdfs (0.1.0)
Description CD File System
State unused (because of an error)
State at Next Boot auto (best state)
Capable auto static loaded unused
Depends On interface HPUX_11_23:1.0

[Anka]

Change the module to loaded:

command line:

#kcmodule -B cdfs=loaded

or do it with SAM, as you feel more comfortable...

[Musa I. S.]

Hurray!!!!!!!! DVD mounted. pls view output below. how do i make the change permanent?

moon2:/#kcmodule -B cdfs=loaded
WARNING: The currently running configuration is not configured to be used at next boot. So, the requested changes will be discarded

Module State Cause Notes

[Anka]

You can set it to static or auto.
See the kcmodule(1m) there is a short description of the different states.

[Musa I. S.]

Thank you so much.
