Dedicating volumes don't have any affect on whether there is an OS VTOC on it or not, it's how Linux was told to format them. If, during dasdfmt, CDL was specified (or taken as a default) there should indeed be an OS VTOC that would allow it to be varied online to z/OS. (It was kind of the whole point of creating the CDL format.) If they are CDL formatted and there is no VTOC, then you have a huge bug that needs to be dealt with. If they are LDL formatted and not CDL, then you need to change your procedure to format them. Mark Post
