CX700 的Clone 卷组和现网数据库主机进行数据和业务的恢复，此时将实施现网数据库主机（XXX-dd01和XXX-dd02）挂接到主用存储 EMC CX700 的Clone卷组,此时数据库主机和存储架构如下图： 即：现网数据库主机（XXX_dd01和XXX_dd02）+EMC CX700，具体恢复实施步骤如下：在进行恢复时可以直接使用每个步骤的内容，进行恢复。1) 备份现网数据库cs_dd01和cs_dd02的vg信息命 令备注说明记录设备的minumber：在XXX_dd01： oracleXXX_dd01：:/oraclell /dev/*/group crw-r- 64 0x000000 /dev/vg00/group crw-rw-rw- 64 0x010000 /dev/vg_arch1/groupcrw-rw-rw- 64 0x030000

/dev/vg_arch2导出vg信息文件2) 停XXX_dd01和XXX_dd02 RAC3) 从主用存储EMC CX700 的stroage group中把XXX数据库所使用的LUN1-LUN7,LUN9-LUN10，从XXX_dd01和XXX_dd02移除4) 主用存储EMC CX700的Clone LUN, LUN 1001LUN 1007,LUN1009LUN1010 bind到XXX_dd01和XXX_dd02上。5) 通过ioscan找到EMC CX 700上bind Clone卷命 令备注说明在XXX_dd01：和XXX_dd02：上执行#iosacn fnC disk 在XXX_dd01：上检查mirror卷信息#insf e 安装硬件信息路径#powermt display dev=all #powermt config#powermt
