This may sound like a stupid question, but do you have a CD in the CDROM drive?

You won't be able to mount it unless there is actually a CD in the drive.

Hi,
Just to make sure, are these your actions ?
mkdir /cdrom
mkdir /SD_CDROM
oscan -fnC disk
Class I H/W Path Driver S/W State H/W Type Description
======================================================================
disk 0 0/0/1/1.15.0 sdisk CLAIMED DEVICE SEAGATE ST318404LC
/dev/dsk/c1t15d0 /dev/rdsk/c1t15d0
disk 1 0/0/2/0.2.0 sdisk CLAIMED DEVICE TOSHIBA CD-ROM XM-5401TA
/dev/dsk/c2t2d0 /dev/rdsk/c2t2d0

ln /dev/dsk/c2t2d0 /dev/cdrom
mount /dev/cdrom /cdrom
# or mount /dev/dsk/c2t2d0 /cdrom if you didn't do the "ln"

If that's ok (and I suppose there is a CD in the drive) you could try the following (replace the hardwarepath with the one for your CD-Drive).
insf -e -H 0/0/2/0.2.0
insf: Installing special files for sdisk instance 1 address 0/0/2/0.2.0

Hope this helps,
Tom Geudens

Hi,

Make sure you are specifying the right device name ( Ensure ensure that you are not specfying device name of harddisk in your system by mistake)

Use "ioscan -kfnC disk" to see the CDROM list or "ioscan -kfnC disk | grep CD-ROM"

Hi,
#ls /dev/dsk
the last file will be of CD

#mount /dev/dsk/cxtxd0 /cdrom

Sometimes I use this trick:

If you have the default /SD_CDROM on your system, try to start swinstall. This program can detect and mount cdroms by itself.
Put in a HPUX-Core cd and if swinstall can detect the cd itself, then (while mount is actief) try to determine what device he actually mounted himself.

Good luck

Hi

i tried mounting the drive with no CD in it and I get message : /dev/dsk/c0t2d0 device busy

I tried putting a new blanks CD and got message

/dev/dsk/c0t2d0: I/O error

have you tried putting the CD into another server to see if you can read it ?

cheers
john.

One thing I didn't see mentioned.

Is the CD drive broken?

On my system I can ioscan 4 cdroms, but only 3 will mount. (All four have CDs in them.)

I know that the 4th is broken as I can't open it and mount returns a 'cd busy' message.
