适用于:

Oracle Database – 企业版- 版本10.2.0.1 到 12.1.0.1 [版本10.2到12.1]
本文档的信息适用于任何平台。

症状

1) 因为接下来的错误,不能安装ASM 磁盘组:
SQL> alter diskgroup bccrecovery mount;
alter diskgroup bccrecovery mount
*
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15040: diskgroup is incomplete
ORA-15042: ASM disk “1” is missing from group number “2”

2) ASM 报告块损坏:

原因

1) “/dev/emcpowerl” (BCCRECOVERY_0001)磁盘被OS卷重叠, 它显示了有关 “LVM2 001” 逻辑卷的OS 元数据(所有的ASM 元数据被清除):

2)““/dev/emcpowerl”磁盘用于创建下一条逻辑OS卷,当它已经指定到 ASM 磁盘组时。
3) 这种重叠损坏了”/dev/emcpowerl” (BCCRECOVERY_0001)磁盘。
解决方法
需要重建 BCCRECOVERY磁盘组,因为BCCRECOVERY 磁盘组,从备份复原的数据库文件被OS重叠, 换句话说,损坏发生在Oracle之外,自从OS卷在“/dev/emcpowerl”磁盘中重叠,它就不能修复。
