LPAR or z/VM mode? Under z/VM, just keep using the old virtual DASD addresses on the new real addresses by updating the z/VM directory for the z/Linux guest and go. If you're in an LPAR, then you're in deep kimchee. Of course, if the person doing the I/O gen is "nice" and you're in an LPAR, he can use HCD to "map" the old device numbers to the new DASD for that one LPAR. But I'll bet he or she isn't that "nice". Oh, and you'd need to somehow copy the entire volume to the new addresses. I think that DFDSS, or FDR can do this. Again, if you're under z/VM, then no changes are need other than to the directory for the z/Linux guest. -- John McKown Senior Systems Programmer UICI Insurance Center Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its content is protected by law.
