本文介绍了如何使用Oracle ASM命令查询和管理磁盘。通过具体示例展示了如何列出所有ASM磁盘、查询特定磁盘信息及确认磁盘别名与实际系统磁盘之间的对应关系。

查看所有磁盘：

[root@node1 init.d]# ./oracleasm listdisks

查看磁盘信息：

[root@node1 init.d]# ./oracleasm querydisk OCRVOL1
Disk "OCRVOL1" is a valid ASM disk

查看别名对应的系统磁盘：

[root@node1 init.d]# ./oracleasm querydisk -v -p OCRVOL1
Disk "OCRVOL1" is a valid ASM disk
/dev/sde: LABEL="OCRVOL1" TYPE="oracleasm" 
/dev/sdo: LABEL="OCRVOL1" TYPE="oracleasm" 
/dev/mapper/ocrvote1: LABEL="OCRVOL1" TYPE="oracleasm" 

[root@node1 init.d]# ./oracleasm querydisk -v -p ASMDATA1
Disk "ASMDATA1" is a valid ASM disk
/dev/sdc: LABEL="ASMDATA1" TYPE="oracleasm" 
/dev/sdm: LABEL="ASMDATA1" TYPE="oracleasm" 
/dev/mapper/data01: LABEL="ASMDATA1" TYPE="oracleasm" 

[root@node1 init.d]# ./oracleasm querydisk -v -p ASMDATA2
Disk "ASMDATA2" is a valid ASM disk
/dev/sdb: LABEL="ASMDATA2" TYPE="oracleasm" 
/dev/sdl: LABEL="ASMDATA2" TYPE="oracleasm" 
/dev/mapper/data02: LABEL="ASMDATA2" TYPE="oracleasm" 

[root@node1 init.d]# ./oracleasm querydisk -v -p ASMDATA3
Disk "ASMDATA3" is a valid ASM disk
/dev/sdd: LABEL="ASMDATA3" TYPE="oracleasm" 
/dev/sdn: LABEL="ASMDATA3" TYPE="oracleasm" 
/dev/mapper/data03: LABEL="ASMDATA3" TYPE="oracleasm" 

[root@node1 init.d]# ./oracleasm querydisk -v -p ASMDATA4
Disk "ASMDATA4" does not exist or is not instantiated
[root@node1 init.d]# ./oracleasm querydisk -v -p ASMDATA6
Disk "ASMDATA6" is a valid ASM disk
/dev/sdf: LABEL="ASMDATA6" TYPE="oracleasm" 
/dev/sdp: LABEL="ASMDATA6" TYPE="oracleasm" 
/dev/mapper/mpathi: LABEL="ASMDATA6" TYPE="oracleasm" 
[root@node1 init.d]#
