You don't say whether you're running under VM or not, but if you are, there is a much easier way to accomplish this task. > We worked out a method to clone the system (for different purposes, > involving different DASD and networking hardware) > .

Much easier to control and if you're clever about it, you can change them all in one place for DR based on the system ID. You can link a completely different set of disks as long as you use the same virtual addresses that you put into the initramd. Wrt to network, use an internal DHCP server that responds only to specific MAC addresses, and assign a specific MAC address to each adapter when you define the virtual NIC (either in the CP directory or in the PROFILE EXEC). In those cases, no changes at all are necessary inside Linux (and if you use the PROFILE EXEC method, you can supply a parameter to PROFILE and get the same effect with much less effort -- eg, PROFILE without a parm is the normal setup, PROFILE TEST gives you a test setup, etc. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
