RMAN SBT_TAPE备份无法被DISK通道识别

发表于 2024 年 7 月 14 日由惜分飞

经过测试确认rman SBT_TAPE通道备份的rman备份集无法被DISK通道(文件系统方式备份)方式恢复,关于rman的SBT_TAPE通道(带库方式备份)备份参考:模拟带库实现rman远程备份
发起SBT_TAPE通道备份备份

O/S-Error: (OS 23) 数据错误(循环冗余检查)—故障处理

发表于 2024 年 6 月 10 日由惜分飞

有客户由于磁盘坏道导致数据文件访问报ORA-27070 OSD-04016 O/S-Error等相关错误

rman 尝试读取88号文件

RMAN> backup datafile 88 format 'e:\rman\%d_%T_%I.%s%p';

检查系统日志,发现有报:设备 \Device\Harddisk0\DR0 有一个不正确的区块

到目前为止基本上可以判断是文件系统或者磁盘层面出现坏道导致该问题（磁盘坏道概率更大）,使用工具对损坏数据文件进行强制拷贝,提示少量扇区数据无法拷贝

通过dbv检查恢复出来文件效果

E:\check_db>DBV FILE=D:/XIFENFEI.ORA

运气不错，就一个数据库block异常,通过dba_extents查询坏块所属对象，运气不太好是一个表数据

SQL> SELECT OWNER, SEGMENT_NAME, SEGMENT_TYPE, TABLESPACE_NAME, A.PARTITION_NAME

  3   WHERE FILE_ID = &FILE_ID
  4     AND &BLOCK_ID BETWEEN BLOCK_ID AND BLOCK_ID + BLOCKS - 1;
输入 file_id 的值:  88
原值    3:  WHERE FILE_ID = &FILE_ID
新值    3:  WHERE FILE_ID = 88
输入 block_id 的值:  323055
原值    4:    AND &BLOCK_ID BETWEEN BLOCK_ID AND BLOCK_ID + BLOCKS - 1
新值    4:    AND 323055 BETWEEN BLOCK_ID AND BLOCK_ID + BLOCKS - 1

设置跳过坏块导出数据，然后重命名原表导入数据,完成本次恢复，以前有过类似恢复:
