I may know this one - we have seen it here in POK. If it's the same
issue it is always during a SLES install and
I'd compare the MVS LPARs "PROFILE.TCPIP"s to each other and see where they are
different for starters.
The fact that it worked several days ago may indicate that mvs configuration

files in your quest for success.
So
Error messages and/or a detailed description of how you know it "cannot find
the CD drive" would help us help you.
