ASM中OCR存储文件疑问

Question

OS: READHAT 5.8
DB: 11.2.0.3
Status of Oracle Cluster Registry is as follows :
         Version                  :          3
         Total space (kbytes)     :     262120
         Used space (kbytes)      :       2908
         Available space (kbytes) :     259212
         ID                       :  917958684
         Device/File Name         :     +OCRDG
                                    Device/File integrity check succeeded
                                    Device/File not configured
                                    Device/File not configured
                                    Device/File not configured
                                    Device/File not configured
         Cluster registry integrity check succeeded
         Logical corruption check succeeded
[grid@rac1 ~]$ asmcmd -p
ASMCMD [+] > cd OCRDG
ASMCMD [+OCRDG] > ls

ASMCMD [+OCRDG] > ls

ASMCMD [+OCRDG] > cd rac*
ASMCMD [+OCRDG/rac-cluster] > ls

ASMCMD [+OCRDG/rac-cluster] > cd ocrfile
ASMCMD [+OCRDG/rac-cluster/ocrfile] > ls
REGISTRY.255.800015219
ASMCMD [+OCRDG/rac-cluster/ocrfile] > OCR存储在ASM中，使用ocrcheck，查找所在磁盘组，asmcmd 下进入磁盘组，未发现具体OCR文件，只有asm spfile
而在共享文件系统如ocfs下存储的OCR可以找到具体文件(如下）
[oracle@bfsty1 ~]$ ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          2
         Total space (kbytes)     :     262144
         Used space (kbytes)      :       3272
         Available space (kbytes) :     258872
         ID                       : 1699483969
         Device/File Name         : /ocfs_data1/crs/ocr.dbf
                                    Device/File integrity check succeeded
         Device/File Name         : /ocfs_data2/crs/ocr2.dbf
                                    Device/File integrity check succeeded
         Cluster registry integrity check succeeded是否在ASM中是无法找到具体文件的？
