cannot mount or boot from cd

I am currently using BL460c blades on a C3000 enclosure. I am running Linux Redhat OS and i'm trying to install a Win Server 2003 which is supposed to boot from the CD.

However, the CD does not boot up during start up, and I can't seem to mount the CD in Linux. (I'm new to linux, so not sure I did it correctly also.)

I logged in as "root", and went to "system tools" -> terminal, and keyyed in :
mount -t iso9660 -o ro /dev/cdrom /cdrom
mount /dev/sud0 /cdrom

both doesn't work. Am I doing it correctly? How can I check if the CDrom has been connected to the blade?

Re: cannot mount or boot from cd

What was the output of mount commands you used?

Re: cannot mount or boot from cd


The output from each command i got is indicative with an arrow(->) as shown below:

mount -t iso9660 -o ro /dev/cdrom /cdrom
-> mount: mount point /cdrom does not exist

mount /dev/sud0 /cdrom
-> mount: you must specify the file system type.

Perhaps it means what it says. Did you try
"mkdir /cdrom"?

Re: cannot mount or boot from cd

What boots during startup, the hard drive? You might need to check the boot order and make sure CDROM is listed as 1st device

if the /cdrom directory doesn't exist, that's the error you will get from the mount command

RH should automount the CD, I think it mounts to a directory under /media

/dev/cdrom is usually a link to the actual device, if the rom drive wasn't connected during install the link may not be there

USB drives are usually seen as SCSI devices

I just checked on one of my c-class systems running SLES10. I used virtual media through iLO2 and mounted an .iso image, it showed up as /dev/sr0. This system was setup using a network install so there is no /dev/cdrom

so you might try

mount /dev/sr0 /mnt
then
ls /mnt

mount will try to determine the type so you generally don't need to use -t and it will mount a CD read only so you don't need the ro option

Re: cannot mount or boot from cd

From the first error it seems that the mountpoint is not present.

please created /cdrom directory using "mkdir /cdrom" as suggested.

Red hat tries to mount a CD in /mnt/cdrom, if you have an entry for /dev/cdrom (or whatever device) in /etc/fstab

try this command:

mount /mnt/cdrom

also check /etc/fstab the path may be different there.....Change accordingly.
