Did you run zipl and mk_initrd?

I am still stuck. When I copy the volumes and then IPL from the new UCB It will only recognize the old volumes but I have changed everything in zipl.conf and fstab. One of my thoughts is that I need to change dasd_mod. During boot I get these messages: Starting udevd Creating devices Loading dasd_mod Loading dasd_eckd_mod *Activating DASDs: 0.0.e3ee:0* This tells me there is something I still need to change, however I do not know where to edit dasd_mod. I assumed it was in /etc/modprob.conf but it is not. How can I change this to activate the new DASD at UCB 0.0.4058 I have read Mark Posts response to this. But I do not know how to "update your parmfile" is this something different than zipl.conf and fstab? http://linuxvm.org/info/HOWTOs/dumprest.html On Mon, Jul 20, 2009 at 12:47 PM, Paul Meier <[email protected]> wrote: > Oh and we are not moving the LPAR but the DASD we are booting from. > > > On Mon, Jul 20, 2009 at 12:34 PM, Paul Meier <[email protected]> wrote: > >> Thanks for the heads up.
