【ASM】Oracleasm命令

1、运行环境

• Linux：Centos 6.5
• Oracle：11.2.0.4.0

2、Oracleasm命令使用说明

[root@strong ~]# oracleasm
Usage: oracleasm [--exec-path=<exec_path>] <command> [ <args> ]
       oracleasm --exec-path
       oracleasm -h
       oracleasm -V

The basic oracleasm commands are:
    configure        Configure the Oracle Linux ASMLib driver
    init             Load and initialize the ASMLib driver
    exit             Stop the ASMLib driver
    scandisks        Scan the system for Oracle ASMLib disks
    status           Display the status of the Oracle ASMLib driver
    listdisks        List known Oracle ASMLib disks
    querydisk        Determine if a disk belongs to Oracle ASMlib
    createdisk       Allocate a device for Oracle ASMLib use
    deletedisk       Return a device to the operating system
    renamedisk       Change the label of an Oracle ASMlib disk
    update-driver    Download the latest ASMLib driver
[root@strong ~]# which oracleasm
/usr/sbin/oracleasm
[root@strong ~]# cd /etc/init.d/
[root@strong init.d]# ./oracleasm 
Usage: ./oracleasm {start|stop|restart|enable|disable|configure|createdisk|deletedisk|querydisk|listdisks|scandisks|status}
[root@strong init.d]# 

3、查看文件系统

[root@strong init.d]# fdisk -l |grep /dev/sd

4、查看asm的状态及磁盘信息

[root@strong init.d]# oracleasm status
Checking if ASM is loaded: yes
Checking if /dev/oracleasm is mounted: yes
[root@strong init.d]# oracleasm listdisks
DATADISK1
DATADISK2
FRADISK3
FRADISK4
[root@strong init.d]# 

5、查看ASM磁盘对应的物理磁盘

[root@strong init.d]# oracleasm querydisk datadisk1
Disk "DATADISK1" is a valid ASM disk
[root@strong init.d]# oracleasm querydisk -d datadisk1
Disk "DATADISK1" is a valid ASM disk on device [8,17]
[root@strong init.d]# ll -t /dev/sd*
brw-rw----. 1 root disk 8, 145 Dec 20 16:45 /dev/sdj1

[root@strong init.d]# oracleasm querydisk -d /dev/sdb1
Device "/dev/sdb1" is marked an ASM disk with the label "DATADISK1"
[root@strong init.d]# 

或者：

[root@strong init.d]# oracleasm querydisk -p datadisk1
Disk "DATADISK1" is a valid ASM disk
/dev/sdb1: LABEL="DATADISK1" TYPE="oracleasm"
