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 I have create a new setup and want to re utilize these disks, i am getting below error


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

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

Why can't you drop it now? –  Andrew Brennan Mar 21 at 14:52
