RAC迁移后恢复ocr、voting disk、spfile

有一套RAC的系统迁移，数据库采用裸设备，采用底层存储同步的方式，包括所有数据文件、ocr、votingdisk、spfile、控制文件、redo log等等。
首先搭建好待迁移的rac和数据库，备份ocr、voting disk、spfile，待底层裸设备全部同步过来后，恢复ocr、voting disk、spfile，直接起库即可。
停crs，备份ocr、voting disk、spfile：
[code]ocrcheck
crsctl query css votedisk
srvctl stop database -d hxcrm
./crsctl stop crs

dd if=/dev/rlv_crmdb2ocr1 of=/oracle/ocrbak/rlv_crmdb2ocr1.bak
dd if=/dev/rlv_crmdb2ocr2 of=/oracle/ocrbak/rlv_crmdb2ocr2.bak

dd if=/dev/rlv_crmdb2vote1 of=/oracle/votebak/rlv_crmdb2vote1.bak
dd if=/dev/rlv_crmdb2vote2 of=/oracle/votebak/rlv_crmdb2vote2.bak
dd if=/dev/rlv_crmdb2vote3 of=/oracle/votebak/rlv_crmdb2vote3.bak

dd if=/dev/rlv_crmdb2spfile of=/oracle/ocrbak/rlv_crmdb2spfile.bak[/code]
待存储同步完后，停crs，恢复ocr vote spfile
[code]srvctl stop database -d hxcrm

./crsctl stop crs

dd if=/oracle/ocrbak/rlv_crmdb2ocr1.bak of=/dev/rlv_crmdb2ocr1 bs=16m count=65
dd if=/oracle/ocrbak/rlv_crmdb2ocr2.bak of=/dev/rlv_crmdb2ocr2 bs=16m count=65

dd if=/oracle/ocrbak/rlv_crmdb2spfile.bak of=/dev/rlv_crmdb2spfile bs=16m count=65

dd if=/oracle/votebak/rlv_crmdb2vote1.bak of=/dev/rlv_crmdb2vote1 bs=16m count=65
dd if=/oracle/votebak/rlv_crmdb2vote2.bak of=/dev/rlv_crmdb2vote2 bs=16m count=65
dd if=/oracle/votebak/rlv_crmdb2vote3.bak of=/dev/rlv_crmdb2vote3 bs=16m count=65[/code]
