Tim,

First, find the device file for you cd drive:

$ ioscan -kfnCdisk
Class I H/W Path Driver S/W State H/W Type Description
============================================================================
disk 0 8/0/19/0.5.0 sdisk CLAIMED DEVICE SEAGATE ST34520WS
/dev/dsk/c1t5d0 /dev/rdsk/c1t5d0
disk 1 8/0/19/0.6.0 sdisk CLAIMED DEVICE QUANTUM VIKING2-4WS
/dev/dsk/c1t6d0 /dev/rdsk/c1t6d0
disk 2 8/16/5.2.0 sdisk CLAIMED DEVICE TOSHIBA CD-ROM XM-5701TA
/dev/dsk/c2t2d0 /dev/rdsk/c2t2d0

Second, insert the disk and issue the mount command:

$ mount /dev/dsk/c2t2d0 /cdrom

(you need to be root)

Third, depending on what's on the cd, you should be able to just cp the files:

cp /cdrom/* /WhereYouWantitToGo

Hope this helps,
Pete

Hi Tim,

Depending on the CD format you may need mount options like:

mount -F cdfs -o cdcase /dev/dsk/cxtydz /mnt_point

You'll know if you need them if when you mount w/o them either
A) ALL filenames are uppercase & they shouldn't be
B) The filnames are "strange" - have trailing characters that don't look right

Rgds,
Jeff

To add to Pete's post:

When you do the copy you probably will want to add the '-Rp' to the cp command. So it would be:

# cp -Rp /cdrom/* /dir/to/copy/to

Hi Tim

Copying is simple like you do betwenn any directories but the key is the mounting. For this you need to knwo the device file for the cd , ioscan -fnC disk | grep CD or DVD to get teh device file .

Then mount using

mount -F cdfs -o cdcase /dev/dsk/cxtydz /cdrom

then use cp to copy from /cdrom to where you want to copy to .

to contuine for the next cd you need to umoun the first cd and then mount the second cd and repeat the cd process . Inc ase you are making copies for the CD , a better option would be to use the CD burner to amek copies.

Hi,

In addition to the above replies, since you have a 2-cd set,

1. Mount the first CD. Copy the contents as indicated above.
2. Unmount the cd. Make sure you are not in that directory.

umount /cdrom

3. Replace CD1 with CD 2. Mount it again. Copy the contents. Unmount and take it out.

If you don't unmount, you cannot chnage the CD.

well the ioscan confirms that my device file is c2ticgsva1:/stand> ioscan -kfnCdisk

but when I mount;

# mount /dev/dsk/c2t2d0 /cdrom
/dev/dsk/c2t2d0: unrecognized file system

I feel pretty dumb... (/cdrom exists)

You are trying to mount a hard disk drive. The device file you want is the one BELOW the line that contains "HP DVD-ROM".

Try that one and you will probably have better luck.

Tim Killinger — Thu, 26 Dec 2002 19:55:43 GMT

OK, so the device file is c3t2d0....

# ioscan -kfnCdisk

disk 5 0/4/0/0.8.0.110.0.0.1 sdisk CLAIMED DEVICE HP A6

mount now says:

# mount /dev/dsk/c3t2d0 /cdrom
mount: /dev/dsk/c3t2d0 on /cdrom : Device busy

and I don't have to umount to eject CD...

is it mounted to someone else? (don't think it can be)

Tim,

What's your $PWD? Are you in /cdrom, perhaps? If not, try fuser to see if someone else is.

What directory are you currently in?

If you happen to be in the /cdrom directory when you try to do a mount, you will get this error.

# pwd
/cdrom

If you do the above and it returns /cdrom, then do a:

# cd /

Then try doing your mount command.

If you want to see if it is already mounted do a:

# cd /cdrom

# ls

If it returns nothing, then chances are it is not already mounted.

Be sure to do a:

# cd /

to get out of the /cdrom directory before trying to do a mount command. Also, be sure to do the above before you try to

# umount /cdrom

to unmount the cd, or else you will get the same error.
