一、查找voting disk 的4种方法
方法1：
[root@RAC1 ~]# crsctl query css votedisk ## STATE File Universal Id File Name Disk group -- ----- ----------------- --------- --------- 1. ONLINE 983f5a2d804d4f81bfddc68e5bcf6e65 (/dev/asm-diskc) [DATA] Located 1 voting disk(s). [root@RAC1 ~]#
方法2：
[grid@RAC1 ~]$ asmcmd dsget parameter:/dev/asm* profile:/dev/asm* [grid@RAC1 ~]$
方法3：
[grid@RAC1 ~]$ gpnptool get
Warning: some command line parameters were defaulted. Resulting command line:
/u01/11.2.0/grid/bin/gpnptool.bin get -o-

Success.
[grid@RAC1 ~]$
方法4：
[grid@RAC1 ~]$ kfed dev=/dev/asm-diskc op=READ | egrep "kfdhdb.vf|ausize" kfdhdb.ausize: 1048576 ; 0x0bc: 0x00100000 kfdhdb.vfstart: 192 ; 0x0ec: 0x000000c0 kfdhdb.vfend: 224 ; 0x0f0: 0x000000e0 [grid@RAC1 ~]$
这里可以看到au是1M，voting disk从AU 192开始，到AU 224结束，共32个AU ：
[grid@RAC1 ~]$ dd if=/dev/asm-diskc bs=1M skip=192 count=32 | od -c > /tmp/vote.out 32+0 records in 32+0 records out 33554432 bytes (34 MB) copied, 1.30292 seconds, 25.8 MB/s [grid@RAC1 ~]$
跳过了头上的192M，dump了后面的32M内容，也就是我们需要的VOTING DISK的32个AU的内容
二、查找ocr的方法
方法1：
[grid@RAC1 ~]$ cat /etc/oracle/ocr.loc ocrconfig_loc=+DATA local_only=FALSE [grid@RAC1 ~]$
方法2：
[grid@RAC1 ~]$ ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 3
Total space (kbytes) : 262120
Used space (kbytes) : 3056
Available space (kbytes) : 259064
ID : 1280092817
Device/File Name : +DATA
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 bypassed due to non-privileged user
[grid@RAC1 ~]$
方法3： ocrdump
方法4：
set lines 120
set pages 100
column name format a40 wra
column type format a10 tru
select af.group_number, af.file_number, aa.name, af.type, af.redundancy
from v$asm_file af, v$asm_alias aa
where aa.file_number = af.file_number and aa.group_number=af.group_number and af.type = 'OCRFILE' ;
SYS% racdb1> select af.group_number, af.file_number, aa.name, af.type, af.redundancy
2 from v$asm_file af, v$asm_alias aa
3 where aa.file_number = af.file_number and aa.group_number=af.group_number and af.type = 'OCRFILE' ;
GROUP_NUMBER FILE_NUMBER NAME TYPE REDUND
------------ ----------- ---------------------------------------- ---------- ------

这里看到ocr的文件号是255，可以根据文件号查询AU:
SQL> set lines 120
SQL> set pages 100
SQL> column name format a40 wra
SQL> column type format a10 tru
SQL> select af.group_number, af.file_number, aa.name, af.type, af.redundancy
