ORA-15001: diskgroup “string” does not exist or is not mounted
Cause: An operation failed because the diskgroup specified does not exist or is not mounted by the current ASM instance.
Action: Verify that the diskgroup name used is valid, that the diskgroup exists, and that the diskgroup is mounted by the current ASM instance.
ORA-15001: diskgroup “string” does not exist or is not mounted 是oracle数据库中常见的错误,该错误表明指定的盘组不存在或未挂载。
ORA-15001: diskgroup “string” does not exist or is not mounted
Cause: An operation was attempted on a diskgroup that does not exist or is not mounted.
Action: Ensure that the specified diskgroup exists, then retry the operation.
1)当进行alter diskgroup操作时,此报错也可能发生。
2)使用create diskgroup操作创建在已经存在的磁盘上时,这个错误也可能发生。
3)在使用drop diskgroup操作删除磁盘组时,这个错误也可能发生。
1)确保指定的磁盘组实际存在,并且已经挂载,也就是磁盘组状态为mounted。
2)要查看磁盘组信息,可以使用sql语句:
select name,state from v$asm_diskgroup;
3)确保相应的文件系统正确,比如对于非ASM盘组,要确保块大小一致,此外,磁盘的扩展属性也需正确无误,最后确保磁盘上的读写权限正确。
4)如果上述步骤检查无误,则可以尝试重新挂载磁盘组。首先,使用drop diskgroup语句移除磁盘组,紧接着,使用create diskgroup或add diskgroup语句重新添加磁盘组。
5)重新添加磁盘组后,可以运行检查磁盘组状态的SQL语句确定磁盘组是否挂载成功。
