hi,

This is a known problem.

Please refer to metalink note: 217319.1

Subject: Raw Device Validation Check When Using DBCA to Create a RAC Database



The problem could be any of:
The raw device is either not readable/writable at the location specified, you are attempting to use a certified shared filesystem (CFS, NFS, etc...), or you do not have user equivelance set up.

Possible solutions are provided there.

kind regards
