文档解释

ORA-15307: disk string not discoverable by CSS; diskgroup string has CSS voting files

Cause: An attempt was made to add a disk which cannot be discovered by Cluster Synchronization Services (CSS). CSS has voting files in the disk group and will not be able to use the new disk if CSS cannot discover the disks.

Action: Update the Automatic Storage Management (ASM) disk string in the Grid Plug and Play (GPnP) profile to include the specified disk and retry the operation. Alternatively, migrate the CSS voting files out of the diskgroup and retry the operation

ORA-15307 错误指出无法在 Cluster Synchronization Services(CSS) 中发现指定的磁盘,而且,某个磁盘组也具有 CSS 的投票文件,这是因为两个系统在注册过程中无法引导 CSS 来识别该磁盘组的位置。

官方解释

ORA-15307 被抛出,是因为 必需的 对象,不能在 CSS 中发现。在某些情形下,在应用程序节点中定义的磁盘组,可能在CSS节点中未定义或未发现,而磁盘文件还存在,在 CSS 节点中使用。

常见案例

在多节点 RAC 环境中运行时,由于磁盘组未在每个节点中注册,并且 CSS 不能识别磁盘组,因此将出现 ORA-15307 错误。

一般处理方法及步骤

1.使用 SRVCTL 查看磁盘组的状态;

2.将该磁盘组的注册信息复制到其他节点;

3.重启 CRS 服务;

4.使用 SRVCTL 重启磁盘组;

5.重新尝试操作该磁盘组。
