本文详细介绍了一次Oracle Real Application Clusters (RAC)及Automatic Storage Management (ASM)的迁移过程，包括数据库停机、磁盘扫描、磁盘组创建、OCR及votedisk迁移等关键步骤。

2.1停止数据库

shutdown immediate

2.2 扫描磁盘

echo 1 > /sys/class/fc_host/host3/issue_lip

echo 1 > /sys/class/fc_host/host4/issue_lip

3，更改磁盘属性

chown oracle:oinstall /dev/mapper/3PART*

4，备份ocr

./ocrconfig -manualbackup

./ocrconfig -showbackup

5，新建asm磁盘组

create diskgroup SYSDG normal redundancy disk '/dev/mapper/3PAR01VOTE01','/dev/mapper/3PAR01VOTE02','/dev/mapper/3PAR01VOTE03' attribute 'compatible.rdbms'='11.2.0.0', 'compatible.asm'='11.2.0.0';

create diskgroup SYSDG external redundancy disk '/dev/mapper/3PARVOT01','/dev/mapper/3PARVOT02','/dev/mapper/3PARVOT03'；

6，迁移votedisk

crsctl query css votedisk

crsctl replace votedisk +SYSDG

crsctl query css votedisk

7，迁移ocr

ocrcheck

ocrconfig -add +SYSDG

ocrconfig -delete +DATA

ocrcheck

8，迁移asmspfile

sqlplus / as sysasm

show parameter spfile

create pfile='/home/oracle/asmpfilebak.ora' from spfile;

create spfile='+SYSDG' from pfile='/home/oracle/asmpfilebak.ora'

9，更换asm磁盘到新存储

alter diskgroup DATA

add disk

'/dev/mapper/3PAR01DATA01',

'/dev/mapper/3PAR01DATA02',

'/dev/mapper/3PAR01DATA03',

'/dev/mapper/3PAR01DATA04',

'/dev/mapper/3PAR01DATA05'

drop disk

DATA_0000,DATA_0001,DATA_0002,DATA_003,DATA_0004 rebalance power 11;

alter diskgroup DATA02

add disk

'/dev/mapper/3PAR01DATA06',

'/dev/mapper/3PAR01DATA07',

'/dev/mapper/3PAR01DATA08',

'/dev/mapper/3PAR01DATA09',

'/dev/mapper/3PAR01DATA10',

'/dev/mapper/3PAR01DATA11',

'/dev/mapper/3PAR01DATA12'

drop disk

DATA_0005,DATA_0006,DATA_007,DATA_0008,DATA_0009,DATA_0010,DATA02_0006 rebalance power 11;

10,检查集群和数据库状态

crsctl stat res -t
