/dev/raw/raw3 MEMBER

CRSDG_0000 /dev/raw/raw1 MEMBER
18.手动加载DATADG磁盘报错
SQL> alter diskgroup DATADG mount;
Diskgroup altered.
SQL> select name,state from v$asm_diskgroup;

CRSDG MOUNTED

19.查看磁盘组磁盘头的状态,可以看到/dev/raw/raw3为member
SQL> select name,path,header_status from v$asm_disk;
NAME PATH HEADER_STATUS
-------------------------------------------------- -------------------------------------------------- ------------------------------
ARCH_0000 /dev/raw/raw2 MEMBER
DATADG_0000 /dev/raw/raw3 MEMBER
CRSDG_0000 /dev/raw/raw1 MEMBER
