Hi,
I had tried kfed but not kfod. Still no joy the 5 missing disks don't show up.
> kfod asm_diskstring='/dev/oradsk/*' disks=all

Also, I trussed the rbal process while attempting to mount the disk group in another session.
See here. http://pastebin.com/pLnNNAin
Not much use though. Yes there are some errors like this
- stat("/dev/oradsk/ASMDA3", 0xFFFFFFFF7FFFCCC0) Err#2 ENOENT
Now we know that /dev/oradsk/ASMDA3 is indeed one of the missing disks as per the old alert log. But all that the truss proves is that the process can't read from these devices that it finds in the asm_diskstring. These could just have been devices that were just left behind by a sloppy administrator!

Fergal
