Abdul,

If you don't have the original DDL stored anywhere for the diskgroup (we dump all our DDL to separate scripts each night), then I suggest checking the underlying physical disks / raw slices for a permissions issue and if they do exist on the server.

Sometimes the MOUNT error message tells you what its looking for. When you do an ALTER DISKGROUP <diskgroup name> MOUNT is there any indication what device isn't getting mounted?

Subject: Diskgroup Mapping in RAC

We have a diskgroup that won't mount due to a missing disk. Is there anyway to get a mapping of disks to diskgroups for unmounted diskgroups to find out which disk is missing? The v$asm_disk view onlys shows info for mounted diskgroups.

Oracle 10.2.0.3.0 RAC on Solaris 10.

Thanks,
Abdul
