Linux下檢視ASM對應磁碟組以及裝置名

在工作上有時候忘記ASM磁碟組所對應的ASM磁碟和裝置名，需要檢視時可以在ASM例項中使用以下命令：

SQL> select name,path from v$asm_disk_stat;

NAME       PATH
---------- --------------------------------------------------
THREE_0000 /dev/oracleasm/disks/VOL3
TWO_0000   /dev/oracleasm/disks/VOL2
ONE_0000   /dev/oracleasm/disks/VOL1

另外希望檢視對應的裝置名稱,可以利用如下命令檢視：

[root@rac1 ~]# /etc/init.d/oracleasm listdisks
VOL1
VOL2
VOL3

[root@rac1 ~]# /etc/init.d/oracleasm querydisk -p VOL1
Disk "VOL1" is a valid ASM disk
/dev/sdc1: LABEL="VOL1" TYPE="oracleasm" 
[root@rac1 ~]# /etc/init.d/oracleasm querydisk -p VOL2
Disk "VOL2" is a valid ASM disk
/dev/sdd1: LABEL="VOL2" TYPE="oracleasm" 
[root@rac1 ~]# /etc/init.d/oracleasm querydisk -p VOL3
Disk "VOL3" is a valid ASM disk
/dev/sde1: LABEL="VOL3" TYPE="oracleasm"
