Hi, jason

Thanks for your reply.

Everything looks right (including ASM module check) before I restart the machine, but OUI can't find the candidate disks. In /tmp/install...log, I found error msg as below: INFO: Parsing KFOD-00305: asmlib initialization error [driver/agent not installed]

I searched "KFOD-00305" keyword in MOS and find nothing.

Then I restart both machine, everything looks exactly the same as before, but ... OUI found the candidate disks and everything moves on.

It's weird but who cares. :-) Cheers!
