I left out some stuff such as mknod etc because they are part of the process ( at least in hpux ) to do a vgcreate.

You can call into oracle support and ask to speak to the on duty manager that's responsible for your sr. Once they call back ( supposed to be in half an hour ) then you can try to get them to expedite it.

In the mean time I would look at all the steps that "should have been" done to setup the raw disk partitions.

Can you use dd command to look at the first 10 blocks? If so do they look like what you expect?

Oracle support has metalink notes on raw device setup and configuration for the various unix platforms and you might want to look at some of those notes. Received on Tue Nov 21 2006 - 14:57:14 CST
