このOracleのサポートでは /dev/mapper/..   AFD:* 、AFD管理対象ディスクを扱う場合は、asm_diskstringとしてを使用する代わりにを使用することを推奨しています。
次のようにasm_diskstringをafd:*のみに変更した後も、renamedgはdev/mapperをasm_diskstringとして選択します。

[grid@nctest ~]$ asmcmd dsget
parameter:AFD:*
profile:AFD:*

SQL> show parameter asm_diskstring

/dev/mapper asm_diskstring ソースDBが変更され、クローニング用に新しいバックアップが作成されたにもかかわらず、SCOは引き続きをピックアップします。
