A typical entry for a (directly connected) CDROM:
Code:
disk      0  0/0/2/0.0.0.0  sdisk      CLAIMED     DEVICE       TEAC    DV-28E-N

Thank you for the suggestion. I ran the command without -k and this was my result:
Code:
[root@hpux04: /dev/dsk]# ioscan -C disk -f -n

Hm, it appears to be the same.

In your example:
Code:
disk      0  0/0/2/0.0.0.0  sdisk      CLAIMED     DEVICE       TEAC    DV-28E-N

^ What about this output tells you it is a CDROM device? I am unsure of what all of the output information means.


EDIT: I think I understand what vbe mentioned earlier. The cdrom device was using the ucb scsi adaptor, so I ran the following command:
Code:
mount -F cdfs -o rr /dev/deviceFileSystem/Usb/MassStorage/dsk/disk@hp-1008+294=A60020000001 /cdrom

the cdrom mounted properly. I am not really sure why the cdrom device appeared under the usb scsi adaptor, when I searched online I did not see this as an example.

Thank you all for the help!
