I have created long time back one ASM RAC setup and I created one diskgroup with some name say xyz. I think that instance is gone but the diskgroup was not dropped exclusively using command:

drop diskgroup xyz including contents;

Now that I have created a new setup and want to re utilize these disks, I am getting below error:

CREATE DISKGROUP XYZ EXTERNAL REDUNDANCY DISK ...

ORA-15003: diskgroup "xyz" already mounted in another lock name space

How can this diskgroup be removed? Any help is appreciated.

Check the diskgroup status in both instances. If it is showing mounted in both instances then:

  1. dismount the diskgroup in all the instance except one. For instance, if you have a 3 node RAC setup, then dismount the diskgroup in nodes 2 and 3.
  2. Drop the diskgroup from the 1st node.
