You mentioned that you added the device before extending your volume, but did you take any steps to ensure that the new dasd is found when the machine boots?

You can probably do all of that stuff in "maintenance mode". ------------------------------------------------------- Josh Heinze [EMAIL PROTECTED] Systems Administrator 773.834.8336 NSIT - DCS - Systems Engineering and Administration The University of Chicago security = 1/convenience On Thu, 17 Jun 2004 [EMAIL PROTECTED] wrote: > I have an existing Linux system (non-VM) running SuSE Enterprise Server 8 in > an LPAR using an IFL.
