1 在存储管理软件中为主机添加4T存储。
2 使用hot_add命令进行更新存储信息 。
存储信息如下
[root@gzrac01 ~]# upadmin

UltraPath CLI #1 >
3 使用fdisk命令对sds和sdt进行分盘
4使用oracleasm创建asm磁盘
[root@gzrac01 ~]# oracleasm createdisk data10 /dev/sds1
Writing disk header: done
Instantiating disk: done
[root@gzrac01 ~]# oracleasm createdisk data11 /dev/sds2
Writing disk header: done
Instantiating disk: done
[root@gzrac01 ~]# oracleasm createdisk data12 /dev/sdt1
Writing disk header: done
Instantiating disk: done
[root@gzrac01 ~]# oracleasm createdisk data13 /dev/sdt2
Writing disk header: done
Instantiating disk: done
oracleasm scandisks
oracleasm listdisks
5创建ASM磁盘组
一个插曲，之前创建的ASM磁盘组均为AU大小为4MB，但是创建脚本采用了默认的1M。切磁盘组添加了数据
create diskgroup dgdata6
external redundancy
disk '/dev/oracleasm/disks/DATA12','/dev/oracleasm/disks/DATA13';
create diskgroup dgdata5
external redundancy
disk '/dev/oracleasm/disks/DATA10','/dev/oracleasm/disks/DATA11';
[grid@gzrac02 ~]$ srvctl start diskgroup -diskgroup dgdata5
[grid@gzrac02 ~]$ srvctl start diskgroup -diskgroup dgdata6
ALTER TABLESPACE HPM1ADD DATAFILE '+DGDATA5' SIZE 30G autoextend off;
ALTER TABLESPACE HPM1ADD DATAFILE '+DGDATA5' SIZE 30G autoextend off;
ALTER TABLESPACE HPM1ADD DATAFILE '+DGDATA5' SIZE 30G autoextend off;
ALTER TABLESPACE HPM1 ADD DATAFILE '+DGDATA5' SIZE 30G autoextend off;
ALTER TABLESPACE HPM1ADD DATAFILE '+DGDATA5' SIZE 30G autoextend off;
6 查看数据库配置信息
[grid@gzrac02 ~]$ srvctl config database -d wyzxdb -a

7重建DISKGROUP6
节点2 dismount dgdata6；
节点1 drop diskgroup dgdata6；
create diskgroup dgdata6
external redundancy
disk '/dev/oracleasm/disks/DATA12','/dev/oracleasm/disks/DATA13' attribute 'compatible.asm'='19.0.0.0.0','compatible.rdbms'='10.1.0.0.0','AU_SIZE'='4M';
Diskgroup created.
8 将DGDATA5上面的文件迁移到DGDATA6;
#####388号数据文件原始位置。
