ASM磁盘增加

BIDB ASM添加磁盘记录
使用 conn /as sysdba
SQL> alter diskgroup DG_DATA add disk '/dev/sdf';
alter diskgroup DG_DATA add disk '/dev/sdf'
*
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15260: permission denied on ASM disk group
使用 conn / as sysasm后正常
SQL> alter diskgroup DG_DATA add disk '/dev/sdf';
alter diskgroup DG_DATA add disk '/dev/sdf'
*
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15031: disk specification '/dev/sdf' matches no disks
ORA-15014: path '/dev/sdf' is not in the discovery set

更改 ASM_DISKSTRING参数:
alter system set asm_diskstring='/dev/diskgroup/','/dev/s*';
alter diskgroup DG_DATA add disk '/dev/sdf';
成功
继续添加磁盘时,提示异常:
SQL> alter diskgroup DG_DATA add disk '/dev/sdg';
alter diskgroup DG_DATA add disk '/dev/sdg'
*
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15075: disk(s) are not visible cluster-wide
该提示在于未在所有节点同时设置 /dev/sdg 的权限,在第二个节点chown后add成功
可参考:http://blog.csdn.net/xiangsir/article/details/8670967
SQL> alter diskgroup DG_DATA add disk '/dev/sdk' rebalance power 6;

Diskgroup altered.
