data磁盘组mount报错ORA-15066
有个oracle rac环境,磁盘组data的冗余度是normal,在主(A)备(B)盘阵上各划分了两块盘,(A1,B1),(A2,B2)。现在的情况是B1,B2丢失,data磁盘组mount不上。
有什么办法可以强制mount吗?
SQL> alter diskgroup data mount force;
alter diskgroup data mount force
*
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15040: diskgroup is incomplete
ORA-15066: offlining disk "" may result in a data loss
ORA-15042: ASM disk "3" is missing from group number "3"
ORA-15042: ASM disk "1" is missing from group number "3"
1、ASM是什么版本?
2、这是真实情况 还是做测试? 刘大,你好
数据库版本是11.2.0.1,是测试环境。
data磁盘组有四个默认的failgroup组,主备存储各2个,现在备存储上的2个丢失,mount的话报错:
SQL> alter diskgroup data mount force;
alter diskgroup data mount force

ORA-15042: ASM disk "3" is missing from group number "3"
ORA-15042: ASM disk "1" is missing from group number "3" normal模式,坏掉两个,那当然mount不上了,数据库都损坏了,怎么可能强制mount

==> normal redundancy 只能损坏 一个failgroup
==> high redundancy 可以损坏 2个failgroup
==> normal redundancy + 4个failgroup 数据还是只存放2份, 这4个failgroup只能损坏其中一个,若损坏2个 那么是不能mount的
