在虚拟机上添加共享磁盘后节点2的ASM实例无法加载到
在节点1用DBCA给ASM增加磁盘图形过程比较容易,新建了两个目录分别是ARCHLOG和BACKUP. 可不能装载节点2上面!
[oracle@node2bdump]$ export ORACLE_SID=+ASM2
[oracle@node2bdump]$ asmcmd
ASMCMD>ll
commands:
--------
cd
du
find
help
ls
lsct
lsdg
mkalias
mkdir
pwd

ASMCMD>ls
ARCHLOG/
BACKUP/

ASMCMD>cd DATA
ASMCMD>ls
MYRAC/
ASMCMD>cd ..
ASMCMD>cd ARCHLOG
无法进入该目录
