 This is not a SCSI error, but an error with your ATAPI (=IDE) CDrom. As far 
as I can see your problem is either:
1) You are trying to mount an audio CD, which is impossible
2) The IDE cable on your CDrom is not connected correctly
3) The CD disk is bad
4) The CD player is bad

 The command should be umount /dev/sda5. Then again, you cannot unmount your / 
filesystem, since the system is running from that. You have been running fsck 
on a live filesystem. Not such a good idea. Didn't you get any warnings?
 If you want to fsck your / you could mark the filesystem as dirty, so it will 
be checked at boot. A *crude* way to do this is to sync the filesystem a 
couple of times and switch the computer off. This is best done from the 
command line and not from X. Make sure nothing is written to disk before the 
syncs and the power down. By the way, I am not responisble for any data loss 
that might occur due to this dirty trick :).
 Of course you can also fsck /dev/sda5 from a rescue system. Try booting from 
the installation CD. This is definitely a neater way to proceed.

 You didn't mention you edited your /etc/inittab. You could have just issued a 
init 1. I also don't understand why your inittab would be readonly, except 
maybe after the fsck on the live filesystem. Check file permissions, or try to 
edit the file from a rescue system. You could just try issueing a init 3 and 
see if your filesystem is now writable.

 This might be a SCSI/IDE problem. Can you boot from SCSI? Look at man 
lilo.conf and check for the parameters "disk=" and "bios=". You might have to 
enter an entry such as
disk=/dev/sda
bios=0x80
Or there might be something wrong with your disk geometry settings. Check your 
BIOS settings. Maybe the option "linear" in lilo.conf might help. And check 
that your /boot partition is below the 1024th cylinder (unless you use a 
recent lilo (not the one on RedHat 6.2).
 If things don't work out, be a little more specific about your system 
parameters (what kind of hd's/sd's, lilo.conf, SCSI adapter, etc.).
