ASM 启动错误
ORA-15032: not all alterations performed
ORA-15063: ASM discovered an insufficient number of disks for diskgroup "groupdisk1"



select name,state from v$asm_diskgroup;
select GROUP_NUMBER,DISK_NUMBER,MOUNT_STATUS from v$asm_disk;

都没有数据。

asmtoolg 看到磁盘status candidate device，重新标记后 stamped asm device。

重新启动asm
select GROUP_NUMBER,DISK_NUMBER,MOUNT_STATUS from v$asm_disk; 有数据

select name,state from v$asm_diskgroup;还是没有数据
