Sanjay, At the very least, the headers for the LUNs utilized by the "sanjay" database need to be cleared up (either via drop diskgroup OR dd OR as a last resort - force option in the create diskgroup while adding to the 2nd RAC environment) - basically anything which clears up the header status of those LUNs/Diskgroups. Once those diskgroups have been cleared up from the metadata of the "sanjay" database, it should be relatively less challenging. -Rajeev On Fri, May 15, 2009 at 1:59 PM, Sanjay Mishra <smishra_97@xxxxxxxxx> wrote: > Hi > > I want to have some insight from somebody who has done the following or has > face such situation. > 3.
