Removing a diskgroup from a corrupt ASM database
Date: Fri, 22 May 2009 11:53:19 -0700 (PDT)
I had a disk failure so that the databases (ASM and actual database) cannot see the disks. Therefore the diskgroup DATA is unmounted and cannot be remounted.
I'm ready to start over from scratch, I dropped the non-ASM database, but still have an ASM database that knows about an unmounted diskgroup. But I cannot drop it because it is unmounted and I cannot mount it because it is corrupt.
What do I do to free up this ASM instance to create a new diskgroup? I'd even drop the entire ASM database but I cannot delete it via DBCA. Short of uninstalling Oracle and reinstalling and creating everything new, what can I do? Received on Fri May 22 2009 - 13:53:19 CDT
