ORA-15130: diskgroup “string” is being dismounted

文档解释

ORA-15130: diskgroup “string” is being dismounted

Cause: The diskgroup is being dismounted by request or because an I/O error was encountered that could not be handled by taking the disks offline. A disk cannot be offlined whenever doing so could result in all copies of a redundant extent being unavailable.

Action: Repair the hardware problem and re-mount the diskgroup. Refer to the alert log to determine which disks have failed.

官方解释

常见案例

1. 当尝试使用ALTER DISKGROUP语句来卸下磁盘组时,可能会引发ORA-15130错误

2. 由于组成磁盘组的磁盘数量从2个变成了1个,可能会引发ORA-15130错误

一般处理方法及步骤

1.使用ALTER DISKGROUP或者DROP DISKGROUP命令来移除磁盘组,以避免ORA-15130错误。

2.检查是否有不可见或不可用的磁盘,以使数据库能正确连接到磁盘组上。

3.使用DBMS_ASH.FLUSH_ASH_NOW功能,及时更新数据库状态,同时检查磁盘组中的磁盘。

4.确保使用正确的ASM_DISKSTRING参数,避免出现之前的错误,这样可以确保磁盘组的连接状态正常。
