八，分区，并使用udev来配置裸设备。
接下来启动，然后分区：
这里在每个磁盘上分别创建1个分区，且把磁盘所有空间都用于这1个主分区。
对共享磁盘分区时，只需要以root用户在任意节点上创建即可，不需要在每个节点上执行！
--------------------------------------------------------------------------------------------------
1.查看各节点磁盘的信息。
节点2上的磁盘分区信息除/dev/sda可能不同之外，其它共享磁盘分区信息应该完全同节点1。

[root@rac1 ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

until you decide to write them. After that, of course, the previous

4.查看各节点信息。
rac1节点
[root@rac1 ~]# ll /dev/sd*
[root@rac1 ~]# ll /dev/sd*
brw-r----- 1 root disk 8, 0 Mar 22 11:06 /dev/sda
brw-r----- 1 root disk 8, 1 Mar 22 11:08 /dev/sda1
brw-r----- 1 root disk 8, 2 Mar 22 11:08 /dev/sda2
brw-r----- 1 root disk 8, 3 Mar 22 11:06 /dev/sda3

brw-r----- 1 root disk 8, 65 Mar 22 11:16 /dev/sde1
这里查看配置裸设备需要的MAJOR和MINOR，如/dev/sdb1的ENV{MAJOR}=="8",ENV{MINOR}=="17"
查案rac2节点
[root@rac2 ~]# ll /dev/sd*
brw-r----- 1 root disk 8, 0 Mar 22 11:07 /dev/sda
brw-r----- 1 root disk 8, 1 Mar 22 11:11 /dev/sda1

brw-r----- 1 root disk 8, 3 Mar 22 11:07 /dev/sda3
brw-r----- 1 root disk 8, 16 Mar 22 11:07 /dev/sdb
brw-r----- 1 root disk 8, 32 Mar 22 11:07 /dev/sdc
brw-r----- 1 root disk 8, 48 Mar 22 11:07 /dev/sdd
brw-r----- 1 root disk 8, 64 Mar 22 11:07 /dev/sde

5.配置裸设备
上述操作需要在双节点执行！且确保在双节点均可以看到裸设备文件，以及oracle用户具有对裸设备的权限
