8.在RAC各节点上添加共享存储硬盘。

添加共享磁盘。在RAC各个节点上，添加创建好的5GB共享磁盘RacDisk1.vmx和RacDisk2.vmx，设备节点选定为SCSI 1:0和SCSI 1:1，SCSI控制器选择“物理”。

创建磁盘分区：

在 rac1 上，以 root 用户身份执行

[root@rac1 ~]# fdisk /dev/sdb

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

Building a new DOS disklabel with disk identifier 0x775483c8.

Changes will remain in memory only, until you decide to write them.

After that, of course, the previous content won't be recoverable.

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

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to

         switch off the mode (command 'c') and change display units to

         sectors (command 'u').
