AIX上给ASM实例使用的磁盘，是LUN还是LV

LUN一般是存储上的概念，是逻辑单元号，常用作存储映射给主机的卷。

LV是逻辑卷，是UNIX *** 作系统的存储组织方式。

对于ASM实例在AIX中识别的是PV，即物理卷。

以下是我的安装文档，有些地方不太完善。

--oracle软件已经正确安装，具体安装步骤参考oracle安装文档：

--根据硬件配置对磁盘分区

fdisk /dev/sdb

--格式分区

mke2fs -j /dev/sdb1

mke2fs -j /dev/sdb2

mke2fs -j /dev/sdb3

mke2fs -j /dev/sdb5

--配置ocssd

以root用户运行$ORACLE_HOME/bin/localconfig

--安装oracleasm lib程序(程序可以从oracle网站上下载)

rpm -Uvh oracleasm-support-2.1.2-1.el4.i386.rpm

rpm -Uvh oracleasmlib-2.0.2-1.i386.rpm

rpm -Uvh oracleasm-2.6.9-42.EL-2.0.3-1.i686.rpm

rpm -Uvh oracleasm-2.6.9-42.ELhugemem-2.0.3-1.i686.rpm

rpm -Uvh oracleasm-2.6.9-42.ELsmp-2.0.3-1.i686.rpm

--创建asm磁盘

转载，仅供参考，祝你愉快，满意请采纳。

（1）添加磁盘。

（2）fdisk格式化。

（3）加载已更新的块设备分区表（在rac的两台机器上执行）(机器可以发现磁盘)

（4）授权。(使oracle用户和响应的组拥有权限)

（5）给磁盘组添加磁盘。（添加到asm磁盘组）

具体举例：

su - grid

sqlplus / as sysasm

alter diskgroup data add disk '/dev/mapper/data15p1'（你格式化后的磁盘）

（6）检查

su - grid

asmcmd

lsdg
