oracle11g ASMCMD-08103报错

出现这个报错有两种可能，一是ASM实例没有运行，二是环境变量ORACLE_SID没有设置成ASM实例。
请看下面例子：
[oracle@11grac1 ~]$ asmcmd
ASMCMD-08103: failed to connect to ASM; ASMCMD running in non-connected mode
ASMCMD> exit

ASM报错，查看一下当前环境变量ORACLE_SID的值:
[oracle@11grac1 ~]$ echo $ORACLE_SID
ora11g1

将ORACLE_SID的值设置为ASM实例
[oracle@11grac1 ~]$ export ORACLE_SID=+ASM1
[oracle@11grac1 ~]$ asmcmd
ASMCMD> lsdsk
