asm 儲存線上遷移

1，備份資料庫。
 
2.2 掃描磁碟
echo 1 > /sys/class/fc_host/host3/issue_lip
echo 1 > /sys/class/fc_host/host4/issue_lip
3，更改磁碟屬性
chown oracle:oinstall /dev/mapper/3PART*
4，備份ocr
./ocrconfig -manualbackup 
./ocrconfig -showbackup
5，新建asm磁碟組
create diskgroup SYSDG external redundancy disk '/dev/mapper/3PARVOT01','/dev/mapper/3PARVOT02','/dev/mapper/3PARVOT03'；
6，遷移votedisk
crsctl query css votedisk
crsctl replace votedisk +SYSDG
crsctl query css votedisk
7，遷移ocr
ocrcheck
ocrconfig -add +SYSDG
ocrconfig -delete +DATA
ocrcheck
8，遷移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，更換asm磁碟到新儲存
alter diskgroup DATA 
add disk
'/dev/mapper/3PARDATA01',
'/dev/mapper/3PARDATA02',
'/dev/mapper/3PARDATA03',
'/dev/mapper/3PARDATA04',
'/dev/mapper/3PARDATA05',  
drop disk
DATA_0000,DATA_0001,DATA_0002,DATA_003,DATA_0004 rebalance power 11;


alter diskgroup DATA02 
add disk
'/dev/mapper/3PARDATA06',
'/dev/mapper/3PARDATA07',
'/dev/mapper/3PARDATA08',
'/dev/mapper/3PARDATA09',
'/dev/mapper/3PARDATA10',
'/dev/mapper/3PARDATA11',
'/dev/mapper/3PARDATA12',  
drop disk
DATA_0005,DATA_0006,DATA_007,DATA_0008,DATA_0009,DATA_0010,DATA02_0006 rebalance power 11;




10,檢查叢集和資料庫狀態
crsctl stat res -t


11，新增新磁碟到磁碟組


alter diskgroup DATA02 add disk '/dev/mapper/3PARDATA13' rebalance power 10;
alter diskgroup DATA add disk '/dev/mapper/3PARDATA14' rebalance power 10;




12，檢查叢集狀態，啟動資料庫
檢查機器狀態
crsctl stat res -t
啟動資料庫
startup
