Just finished fresh 5.2 install with ML-06 on a pSeries 610 and now I'm
after installing some software from the cd-rom.

The device cd0 is showing available. I've tried to remove and add a
CDROM filesystem and I am still unable to mount the /cdrom fs.

Last week when I was working on this server I finished the installation
and as able to mount /cdrom all day long.

After this rebuild, it is not wanting to work. I see no errors in
errpt.

This is the error I'm getting when I mount /cdrom from the prompt:

mount: 0506-324 Cannot mount /dev/cd0 on /cdrom: A system call received
a parameter that is not valid.

When I try to mount through smitty:

mount: 0506-324 Cannot mount /dev/cd0 on /cdrom: The file system has
read permission
only.
