Exadata下新建DiskGroup

Exadata下新建Asm Diskgroup 的步骤大致如下：

1.使用dcli -g /home/oracle/cell_group -l root cellcli -e list griddisk 命令找出active的griddisk

[root@dm01db01 ~]# dcli -g /home/oracle/cell_group -l root cellcli -e list griddisk

注意若没有符合要求的griddisk，你可以使用’cellcli -e drop griddisk’和’cellcli -e create griddisk’命令重建griddisk ，但是不要轻易drop DBFS_DG开头的griddisk

2.登陆ASM实例后create disk group

如果不知道CELL的IP，可以从下面的配置文件中找到

[root@dm01db02 ~]# cat /etc/oracle/cell/network-config/cellip.ora 
cell="192.168.64.131"
cell="192.168.64.132"
cell="192.168.64.133"

SQL> create diskgroup DATA_MAC normal  redundancy 
  2  DISK
  3  'o/192.168.64.131/RECO_DM01_CD_*_dm01cel01'
  4  ,'o/192.168.64.132/RECO_DM01_CD_*_dm01cel02'
  5  ,'o/192.168.64.133/RECO_DM01_CD_*_dm01cel03'
  6  attribute
  7  'AU_SIZE'='4M',
  8  'CELL.SMART_SCAN_CAPABLE'='TRUE',
  9  'compatible.rdbms'='11.2.0.2',
 10  'compatible.asm'='11.2.0.2'
 11  /

3. MOUNT 新建的DISKGROUP

ALTER DISKGROUP DATA_MAC mount ;

4.或使用crsctl start/stop resource ora.DATA_MAC.dg 控制该资源
