使用force扩容asm_diskgroup
来源：互联网 发布：linux解压命令rar 编辑：程序博客网 时间：2024/04/28 13:56
案例描述：
同事在rac上扩asm磁盘，由于没有修改hdisk的reserve_policy属性，导致另外一个节点看不到磁盘，而能看见磁盘的节点也无法使用节点。

加不进去，disk '/dev/rhdisk8' belongs to diskgroup "CALLDG"，但实际SELECT name, header_status, path FROM V$ASM_DISK ;看不到name。。。
这时使用force命令：
SQL> alter diskgroup CALLDG add disk '/dev/rhdisk8' force;
Diskgroup altered.
SQL> select TOTAL_MB from v$asm_diskgroup;
TOTAL_MB
----------
409600
成功了。。。
