ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15130: diskgroup "ARCH" is being dismounted
ORA-15066: offlining disk "ARCH_0001" in group "ARCH" may result in a data loss
ORA-15196: invalid ASM block header [kfr.c:8522] [endian_kfbh] [3] [10805] [0!= 1]
重啟時磁碟頭有問題，粗暴地解決的這個問題 。前提是磁碟組ARCH 內容可棄
ALTER DISKGROUP ARCH DROP DISK '/dev/asm-diskg' force;
DROP DISKGROUP ARCH FORCE
清一下磁碟頭資訊：
dd if=/dev/zero of=/dev/asm-diskg bs=8192 count=128000
su - grid
asmca 重新建立diskgorup ARCH
以下是學習筆記：
清除ASM磁碟資訊：
dd if=/dev/zero of=/dev/sdxx bs=8192 count=128000
alter diskgroup DATA dismount;
drop diskgroup DATA force including contents;
srvctl remove diskgroup -g DATA -f
create diskgroup data2 external redundancy disk '/dev/asm-diskd';
