一、环境描述
rhel 6.6 + Oracle 11.2.0.4
存储更换，需要添加新盘，替换掉旧的存储盘，以下为测试步骤。

二、测试过程
[root@roidb1 ~]# cd /etc/udev
[root@roidb1 udev]# ls
makedev.d  rules.d  udev.conf
[root@roidb1 udev]# cd rules.d/
[root@roidb1 rules.d]# ls

##添加一块新盘
[root@roidb1 rules.d]# scsi_id --whitelisted --replace-whitespace --device=/dev/sdf

##修改配置文件

##重启udev服务，加载配置文件
[root@roidb1 rules.d]# start_udev

##查看asm磁盘

##使用sysasm添加磁盘
alter diskgroup datadg add disk '/dev/asm-diskf' ;

##加快平衡速度，power=0就是停止rebalance操作，不建议使用11
alter diskgroup datadg rebalance power 11;           

SQL> alter diskgroup datadg rebalance power 11;

Diskgroup altered.

alter diskgroup datadg drop disk 'DATADG_0000'; --按照name来删除

alter diskgroup datadg rebalance power 11;
