Oracle ASM配置教程：不依赖oracleasm的磁盘设置

用UDEV来创建ASM磁盘组
 /dev/sdd

  scsi_id --whitelisted --replace-whitespace --device=/dev/sdb
  scsi_id --whitelisted --replace-whitespace --device=/dev/sdc
  scsi_id --whitelisted --replace-whitespace --device=/dev/sdd
创建配置文件
/etc/udev/rules.d/99-oracle-asmdevices.rules

for i in b c d;
do
echo "KERNEL==\"sd*\", BUS==\"scsi\", PROGRAM==\"/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\", 
RESULT==\"`/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`\", 
NAME=\"asm-disk$i\", OWNER=\"grid\", GROUP=\"asmdba\", MODE=\"0660\""  
    >> /etc/udev/rules.d/99-oracle-asmdevices.rules
done

生效配置文件
/sbin/start_udev

使用vmware，需要在vmx文件中加入： disk.EnableUUID = "TRUE"，否则UUID出不来

绑定磁盘分区搞定：

[root@racdb1 ~]# partprobe --另外一个节点这样识别一下就看到/dev/asm-disk* 了
