4、d01和XXX_dd02）+EMC CX3-40F，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，进行数据和业务恢复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_lock/group crw-rw-rw- 64
