You don't format SCSI disks, unless you're talking about putting a file system on it. -snip- > No configuration file for adapter 0.0.5000 I don't like this message, especially since in one of your other emails you showed that you did have a configuration file that you created in YaST. -snip- > I had to manually add a LUN 0 in order to see anything at all.

That's why you don't use names like /dev/sd?, you use the persistent names under /dev/disk/by-id/. I really recommend using the lszfcp and zfcp_san_disc tools included in s390-tools RPM. They can help you figure out what LUNs are available to you, and see if they correlate at all with what the SAN admins are telling you.
