至此共享存储配置完成；

共享存储划分分区，因为存储是做的raid5，存储容量大约在40G左右，所以划分三个主分区，作为ASM磁盘组使用，另外划分若干扩展分区，使用作为安装OCR和spfile；这里只需要在一个节点上做就可以了，因为存储是共享的。 [root@rac1 ~]# fdisk /dev/sda

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel. Changes will remain in memory only, until you decide to write them. After that, of course, the previous content won't be recoverable.

The number of cylinders for this disk is set to 40959. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with:

1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK)

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

分区划分完成后，检查分区结果，两个节点分别做检查。 [root@rac1 ~]# fdisk -l

5、映射裸设备

映射裸设备，分别在两个节点上配置，在这里映射的是扩展分区，而不是主分区，主分区是用来做ASM磁盘组安装数据库的。 [root@rac1 ~]# vi /etc/sysconfig/rawdevices /dev/raw/raw1 /dev/sda5
