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
