Not running AIX at my shop but I guess the first question I would ask you is did you go through all the steps ( whatever they are on AIX ) to properly create a raw volume?

On hpux that would be vgcreate and lvcreate then change permissions on the raw partitions.

Looks to me as if this is an item that you should probably work with oracle support on. Received on Tue Nov 21 2006 - 10:55:02 CST
