6.2 配置asm卷

1) 创建共享ASM磁盘卷

Rac1上：

/etc/init.d/oracleasm configure

Defaultuserto ownthedriverinterface[]:oracle

Defaultgroupto ownthedriverinterface[]:dba

StartOracleASMlibrarydriveronboot(y/n) [n]:y

FixpermissionsofOracleASMdisksonboot(y/n) [y]:y

WritingOracleASMlibrarydriverconfiguration:[ OK ]

Loadingmodule"oracleasm":[ OK ]

MountingASMlibdriverfilesystem:[ OK ]

ScanningsystemforASMdisks:[ OK ]

Rac2上：

/etc/init.d/oracleasm configure

Defaultuserto ownthedriverinterface[]:oracle

Defaultgroupto ownthedriverinterface[]:dba

StartOracleASMlibrarydriveronboot(y/n) [n]:y

FixpermissionsofOracleASMdisksonboot(y/n) [y]:y

WritingOracleASMlibrarydriverconfiguration:[ OK ]

Loadingmodule"oracleasm":[ OK ]

MountingASMlibdriverfilesystem:[ OK ]

ScanningsystemforASMdisks:[ OK ]

Rac1上： -- 创建卷

/etc/init.d/oracleasm createdisk VOL1 /dev/sdd1

/etc/init.d/oracleasm createdisk VOL2 /dev/sde1

/etc/init.d/oracleasm scandisks -- 扫描ASM卷

/etc/init.d/oracleasm listdisks -- 显示ASM卷

能看到: VOL1 VOL2

Rac2上：

/etc/init.d/oracleasm scandisks -- 扫描ASM卷

/etc/init.d/oracleasm listdisks -- 显示ASM卷

能看到: VOL1 VOL2

6.3 oracleasm命令详解

./oracleasm configure

./oracleasm enable/disable #重启后是否自动启动asmlib

./oracleasm start/stop/restart #在吧重启系统的情况下，启动和关闭asmlib。

./oracleasm createdisk

./oracleasm deletedisk

./oracleasm querydisk /dev/sdb1

./oracleasm scandisks

./oracleasm listdisks
