Installation Problems Redhat 7.1

["Thomas, Rick" <ThomasR tss3 orl lmco com>]

Trying to install RedHat 7.1
Problems with SCSI cdrom (open failed)
Error message reads;
Partition check
Sda: sda1 sda2 sda3 sda4
cdrom: opened failed
scsi cdrom error: host 0 channel 0 id3 lun 0 return code = 28000002


Tried installing disk on hard drive (copied okay, copied using cp -a
/cdrom/RedHat RedHat7.1)
Error message says
Device /dev/sda1 does not apear to contain Red Hat CDROM images

It appears that I have a bad image of RedHat 7.1or my cdrom drive may be
bad, I would appreciate any suggestions
