Oracle10gRACASM存储迁移
使用VBOX模拟存储迁移的环境，OS：
RHEL5.9，DB：
Oracle10.2.0.4RACASM2Nodes。
ASM使用ExternRedundancy，不使用ASM的rebalance功能，ocr和votedisk存放在raw里。
迁移包括controlfile，datafile，tempfile，spfile，ocr，votedisk。
迁移前路径
ocr /dev/sdf1 /dev/raw/raw1, /dev/sdf2 /dev/raw/raw2
votedisk /dev/sdg1 /dev/raw/raw3, /dev/sdg2 /dev/raw/raw4, /dev/sdg3 /dev/raw/raw5
ASM +DATA /dev/sdb
ASM +FRA /dev/sdc
迁移后路径
ocr /dev/sdh1 /dev/raw/raw6, /dev/sdh2 /dev/raw/raw7
votedisk /dev/sdi1 /dev/raw/raw8, /dev/sdi2 /dev/raw/raw9, /dev/sdi3 /dev/raw/raw10
ASM +DATAFG /dev/sdd
ASM +FRADG /dev/sde
迁移votedisk和ocr
