How do I mount a DVD in RHEL 5?

I am attempting to mount a the installation DVD for Red Hat Enterprise Linux 5 so that I can install an additional RPM.  The system was installed barebones (it's a server, so all install options were unchecked except base).  Every time I try and mount the DVD I get the error:

mount: No medium found

I have googled extensively, and can't find anything that works.

Troubleshooting steps taken:
1) DVD is good and drive hardware is good (it's the same ones I just used to install the OS)
2) Rebooting
3) Trying to mount as both udf or iso9660
4) Using various /dev points to try and mount from (cdrom, cdwriter, dvd, dvd-hda, hda)
5) Tried to mount in both /mnt/dvd and /media/dvd
6) Editing /etc/fstab to try and mount from there

Other notes: Drives are SAS, so hda isn't the harddrive.
#General syntax I'm using
mount -t iso9660 /dev/hda /media/dvd
#fstab line
/dev/hda /media/dvd iso9660 ro,noauto 0 0
#dmesg | grep hda output
ide0: BM-DMA at 0x0500-0x0507, BIOS settings: hda:DMA, hdb:pio
hda: ATAPI 24x DVD-ROM CD-R/RW drive, 1536kB Cache, UDMA(33)

try this
/dev/hda       /media/cdrom1   udf,iso9660 user,noauto,exec,utf8 0       0
if you are not root you should have "user" in /etc/fstab in order to mount
i mean you should enter this line into /etc/fstab
/dev/hda       /media/dvd   udf,iso9660 user,noauto,exec,utf8 0       0
and then
mount /media/dvd

What makes you sure that it is /dev/hda

try this from the command line

mount /dev/hda /nt

it should show a message that it will mount as read only

I had the same result

small student:
Please see the dmesg output from above.  Your command gives an error that the mount point does not exist.

So on a "I've tried everything else" hunch, I opened the drive, took the DVD out, put it back in, and closed the drive.  Ran mount and it worked fine, so I guess it was just the disk sitting funny in the drive.
