Could you please help me with how to identify the diskname as I am getting the below error "no such file or directory" when trying to fix the header corruption in one of the ASM disk -> I am trying to follow metalink note Fixing header corruption in 2nd AU using dd command in ASM ( Doc ID 2080471.1 )
