ASM磁盘配置（Oracle RAC 11g）
ASM磁盘配置
1、规划需要的共享磁盘个数及大小
注解：以上代码中，”d、e、f”代表加载的共享硬盘sdd~sdf。请根据实际情况修改。 硬盘必须是新硬盘（无分区，没有被格式化），否则Grid无法安装
2、配置ASM磁盘（创建文件99-oracle-asmdevices.rules）
运行下面命令创建配置文件99-oracle-asmdevices.rules
方式一：利用脚本的方式创建99-oracle-asmdevices.rules
[root@i-5ibi1e5j rules.d]# cat a.sh
#!/bin/bashecho "options=--whitelisted --replace-whitespace">/etc/scsi_id.config
i=1
id=''
for x in d e f
do
id=`scsi_id --whitelisted --replace-whitespace --device=/dev/sd$x`
echo "KERNEL==\"sd*\", SUBSYSTEM==\"block\", PROGRAM==\"/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\", RESULT==\"$id\", NAME=\"asm-disk$i\", OWNER=\"grid\", GROUP=\"asmadmin\", MODE=\"0660\"">>/etc/udev/rules.d/99-oracle-asmdevices.rules
let i++
done
3、启动udev
 |
4、检查udev是否正常配置
5、测试udev设备
[root@i-5ibi1e5j dev]# udevadm info --query=all --path=/sys/block/sdd
