ORA-15411: Failure groups in disk group DATA have different number of disks.
客户磁盘组以前规划是normal模式,但是由于某种原因,其中一个存储掉线了,出现一下状态

因为磁盘空闲空间较大

想从data磁盘组中,删除部分盘,释放出来一些空间,结果报ORA-15411: Failure groups in disk group DATA have different number of disks.
SQL> alter diskgroup data drop disk DATA_0027,DATA_0026,DATA_0025,DATA_0024 rebalance power 10; alter diskgroup data drop disk DATA_0027,DATA_0026,DATA_0025,DATA_0024 rebalance power 10 * ERROR at line 1: ORA-15032: not all alterations performed ORA-15411: Failure groups in disk group DATA have different number of disks.
设置,删除磁盘成功_asm_disable_failgroup_size_checking和_asm_disable_dangerous_failgroup_checking
